The red imported fire ant is one of the worlds most devastating invasive species, adversely affecting humans, wildlife, crops, and livestock. To control infestations, chem. pesticides are deployed extensively around the world. However, their extensive use has led to neg. effects on the environment and human health. Essential oils, which are safe and ecofriendly, can potentially be used as alternatives to chem. pesticides. In this study, grapefruit essential oils were used as fumigant agents to control red imported fire ants. The crude grapefruit oil (GO1) contained 28 compounds, and the concentrated grapefruit oil (GO2), which was refined from GO1 by vacuum distillation, contained 20 compounds D-Limonene was the dominant constituent in both GO1 (70.1%) and GO2 (73.96%), and other important constituents included 尾-pinene, 伪-pinene, 尾-phellandrene, octanal, d-carvone, 伪-terpineol, and linalool. Both the essential oils and their individual constituents (伪-pinene, 伪-terpineol, 尾-phellandrene, octanal, and d-carvone) showed strong lethal fumigant effects against workers. Workers were more susceptible to GO2 than GO1, and octanal was more toxic to workers as compared with the other four constituents. When antennas of workers were treated with the two oils or the five constituents, their walking and gripping abilities were significantly suppressed, and there was an obvious bending or breaking phenomenon on the sensilla of the antennas. Fumigant activity by grapefruit essential oils and their main compounds were associated with their effects on the walking and gripping behavior of workers, and this confirmed that grapefruit essential oil is a promising, ecofriendly, and safe fumigant for the control of red imported fire ants. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Synthetic Route of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Synthetic Route of C10H20O2

Removal of citric acid from water by tributyl amine in octyl acetate: equilibrium and optimization by central composite design was written by Evlik, Tais;Asci, Yavuz Selim;Baylan, Nilay;Cehreli, Suheyla. And the article was included in Desalination and Water Treatment in 2020.Application of 112-14-1 The following contents are mentioned in the article:

Citric acid is one of the most important natural organic acid and extensively used in pharmaceuticals, foods, beverages, personal care products and mainly manufactured in the form of aqueous solutions by fermentation processes. In this study, the removal of citric acid from aqueous solutions was investigated by reactive extraction using an extractant namely tributylamine (TBA) in octyl acetate. The effects of different parameters on the removal such as initial extractant (TBA) concentration in octyl acetate (0-1.2 mol L-1), initial citric acid concentration (0.26-0.78 mol L-1) and, organic: aqueous phase ratio (0.2-1.0 volume/volume) were examined In order to evaluate the performance of reactive extraction operation, extraction efficiencies (E%), distribution coefficients (D) and loading factors (Z) were calculated by using the exptl. data. Furthermore, an optimization work was carried out for the reactive extraction process of citric acid. Response surface methodol. was used to optimize the effect of input variables on the reactive extraction In the variables examined, it was determined that the initial TBA concentration in the organic phase was the most effective parameter for the removal of citric acid from aqueous solutions The optimum extraction conditions were found to be initial TBA concentration in the organic phase of 1.2 mol L-1, the initial citric acid concentration of 0.26 mol L-1 and organic: aqueous phase ratio of 1.0 (volume/volume), resp. Under these optimum conditions, the predicted and exptl. extraction efficiencies were obtained as 86.31% and 82.44%, resp. The correlation coefficient values (R2 and adjusted R2 > 0.9) denoted that the obtained model equation represents the exptl. data adequately. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Application of 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Metabolic, organoleptic and transcriptomic impact of Saccharomyces cerevisiae genes involved in the biosynthesis of linear and substituted esters was written by Marullo, Philippe;Trujillo, Marine;Viannais, Remy;Hercman, Lucas;Guillaumie, Sabine;Colonna-Ceccaldi, Benoit;Albertin, Warren;Barbe, Jean-Christophe. And the article was included in International Journal of Molecular Sciences in 2021.Computed Properties of C10H20O2 The following contents are mentioned in the article:

Esters constitute a broad family of volatile compounds impacting the organoleptic properties of many beverages, including wine and beer. They can be classified according to their chem. structure. Higher alc. acetates differ from fatty acid Et esters, whereas a third group, substituted Et esters, contributes to the fruitiness of red wines. Derived from yeast metabolism, the biosynthesis of higher alc. acetates and fatty acid Et esters has been widely investigated at the enzymic and genetic levels. As previously reported, two pairs of esterases, resp. encoded by the paralogue genes ATF1 and ATF2, and EEB1 and EHT1, are mostly involved in the biosynthesis of higher alc. acetates and fatty acid Et esters. These esterases have a moderate effect on the biosynthesis of substituted Et esters, which depend on mono-acyl lipases encoded by MGL2 and YJU3. The functional characterization of such genes helps to improve our understanding of substituted ester metabolism in the context of wine alc. fermentation In order to evaluate the overall sensorial impact of esters, we attempted to produce young red wines without esters by generating a multiple esterase-free strain (未atf1, 未atf2, 未eeb1, and 未eht1). Surprisingly, it was not possible to obtain the deletion of MGL2 in the 未atf1/未atf2/未eeb1/未eht1 background, highlighting unsuspected genetic incompatibilities between ATF1 and MGL2. A preliminary RNA-seq anal. depicted the overall effect of the 未atf1/未atf2/未eeb1/未eht1 genotype that triggers the expression shift of 1124 genes involved in nitrogen and lipid metabolism, but also chromatin organization and histone acetylation. These findings reveal unsuspected regulatory roles of ester metabolism in genome expression for the first time. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Computed Properties of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Computed Properties of C10H20O2

Interfacial Catalysis in Biphasic Carboxylic Acid Esterification with a Nickel-Based Metallosurfactant was written by Toth, Andreas;Schnedl, Silke;Painer, Daniela;Siebenhofer, Matthaeus;Lux, Susanne. And the article was included in ACS Sustainable Chemistry & Engineering in 2019.Related Products of 112-14-1 The following contents are mentioned in the article:

A metallosurfactant catalyst was developed to address the requirements for the utilization of low-mol.-weight carboxylic acids from dilute effluents. The catalyst Ni(DBSA)₂ combines transition-metal catalysis of nickel ions and surfactant catalysis of 4-dodecylbenzenesulfonic acid (4-DBSA). Requirements for the metallosurfactant catalyst are low water solubility, high catalytic activity in biphasic esterification, and self-assembling properties at the interface. Ni(DBSA)₂ was tested for applicability in the interfacial catalysis of esterification of dilute acetic acid with the solvent 1-octanol and resulted in an octyl acetate yield of 31.3%. Under identical reaction conditions, Ni(DBSA)₂ performed better than sulfuric acid with a yield of 1.7%. The limited catalytic performance of sulfuric acid is caused by the presence of sulfuric acid mainly in the aqueous phase. In contrast, Ni(DBSA)₂ is dissolved in the solvent and assembles at the aqueous/solvent interface where the reaction takes place. Addnl., the metallosurfactant lowers the interfacial tension between 1-octanol and deionized water by up to 75%, thus enhancing mass transfer. Compared to catalysis with 4-DBSA in emulsion, the catalytic performance of Ni(DBSA)₂ dropped by 62%, but this drawback is compensated by the complete suppression of emulsification. With Ni(DBSA)₂, the development of a catalyst was achieved, which self-enhances its catalytic performance in the interfacial catalysis through increased mass transfer area due to its surfactant properties. A nickel-based metallosurfactant is used to enhance the valorization of low-mol.-weight carboxylic acids from aqueous biobased effluents. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 112-14-1).

Inoculation of grape musts with single strains of Saccharomyces cerevisiae yeast reduces the diversity of chemical profiles of wines was written by Philipp, Christian;Bagheri, Bahareh;Horacek, Micha;Eder, Phillip;Bauer, Florian Franz;Setati, Mathabatha Evodia. And the article was included in PLoS One in 2021.Recommanded Product: 112-14-1 The following contents are mentioned in the article:

Anecdotal evidence suggests that spontaneous alc. fermentation of grape juice is becoming a more popular option in global wine production Wines produced from the same grape juice by inoculation or spontaneous fermentation usually present distinct chem. and sensorial profiles. Inoculation has been associated with more similar end-products, a loss of typicity, and lower aroma complexity, and it has been suggested that this may be linked to suppression of the local or regional wine microbial ecosystems responsible for spontaneous fermentations However, whether inoculated fermentations of different juices from different regions really end up with a narrower, less diverse chem. profile than those of spontaneously fermented juices has never been properly investigated. To address this question, we used grape juice from three different varieties, Gruuner Veltliner (white), Zweigelt (red), and Pinot noir (red), originating from different regions in Austria to compare spontaneous and single active dry yeast strains inoculated fermentations of the same grape samples. The chem. anal. covered primary metabolites such as glycerol, ethanol and organic acids, and volatile secondary metabolites, including more than 40 major and minor esters, as well as higher alcs. and volatile fatty acids, allowing an in depth statistical evaluation of differences between fermentation strategies. The fungal (mainly yeast) communities throughout fermentations were monitored using automated ribosomal intergenic spacer anal. The data provide evidence that inoculation with single active dry yeast strains limits the diversity of the chem. fingerprints. The fungal community profiles clearly show that inoculation had an effect on fermentation dynamics and resulted in chem. less diverse wines. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Recommanded Product: 112-14-1).

On-Line Coupling of Simultaneous Distillation-Extraction Using the Likens-Nickerson Apparatus with Gas Chromatography was written by Liao, Pei-Han;Yang, Hui-Hsien;Wu, Pei-Chi;Abu Bakar, Noor Hidayat;Urban, Pawel L.. And the article was included in Analytical Chemistry (Washington, DC, United States) in 2020.COA of Formula: C10H20O2 The following contents are mentioned in the article:

Simultaneous distillation-extraction (SDE) using the Likens-Nickerson apparatus is a convenient technique used to isolate volatile organic compounds (VOCs) from complex liquid matrixes. The technique combines steam distillation with solvent extraction While anal. extractions are normally followed by off-line separation/detection, it is advantageous to couple extractions online with separation and detection systems that are employed in the same anal. workflow. Here, we have coupled the Likens-Nickerson apparatus online with a gas chromatograph hyphenated with a mass spectrometer. For that purpose, we have devised an automated liquid transfer setup comprising a peristaltic pump, control unit, customized transfer vial with a drain port, and an autosampler arm to deliver liquid extract aliquots at defined time points. The online SDE-GC/MS system enables one to record real-time extraction profiles. These profiles reveal extraction kinetics of various VOCs present in the extracted samples. The data sets were fitted with the first order kinetic equation to obtain numeric values characterizing the extraction process (rate constants ranging from 0.21 to 0.01 min^-1 for the Et esters from C₆ to C₁₉). A comparison of online and off-line results reveals that the online system is more dependable, while the off-line anal. leads to artifacts. To demonstrate the operation of the online SDE-GC/MS system, we performed analyses of selected real samples (beer). The real-time data sets revealed extraction kinetics for VOCs present in these samples. The devised extraction-anal. system allows the analysts to make an evidence-based decision on the extraction time for different groups of analytes in order to maximize extraction yield and minimize analyte losses. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C10H20O2

Essential oils and volatile emission of eight South African species of Helichrysum grown in uniform environmental conditions was written by Najar, B.;Cervelli, C.;Ferri, B.;Cioni, P. L.;Pistelli, L.. And the article was included in South African Journal of Botany in 2019.COA of Formula: C10H20O2 The following contents are mentioned in the article:

This paper reported for the first time the aroma profile and essential oil composition of eight species of Helichrysum endemic in South Africa but grown in Italy (CREA-Sanremo collection). The volatiles of all the studied Helichrysum were dominated by monoterpene hydrocarbons, except for H. basalticum, where sesquiterpene hydrocarbons was the main class of compounds with 尾-caryophyllene (13.7%) and 伪-guaiene (11.9%) as major components.Despite the great diversity of compounds obtained in the volatile emission (more than 130), only four compounds were responsible for at least 34% of the identified fraction. These compounds were: sabinene (16.0%), 尾-caryophyllene and 伪-guaiene in H. basalticum; sabinene (57.7%) in H. foetidum; (Z)-尾-ocimene (34.6%), tricyclene (16.2%) and myrcene (10.0%) in H. incanatum; myrcene (29.3%), tricyclene (21.5%) and limonene in H. indicum; tricyclene (32.1%) and (E)-3-hexanol acetate (20.1%) in H. montanum; limonene (10.3%), sabinene (8.9%), 1-decene (7.6%) and 1-hexanol (7.0%) in H. mutabile; 伪- and 尾-pinene in H. patulum (27.6% and 44.9%, resp.) and 伪-pinene (36.3%) and 伪-fanchene(15.6%) in H. setosum.The EOs composition of these species was also different from each other with sesquiterpene compounds as the prevalent class. Valerianol (16.3%, os, in H. basalticum), ledol (16.3%, os, in H. foetidum), 尾-caryophyllene (11.0% and 13.4%, sh, in H. indicum and H. patulum, resp.), viridiflorol (18.3%, os, in H. montanum) and valerianol (30.1%, os in H. setosum) were found to be the main constituents. It is worthy to highlighting that the H. incarnatum EO showed a similar behavior to that of the spontaneous emission with a predominance of monoterpene hydrocarbons (60.7% in EO vs 81.4% in VOC), both represented by (Z)-尾-ocimene as main constituent. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).

Fingerprinting the volatile profile of traditional tobacco and e-cigarettes: A comparative study was written by Berenguer, Cristina;Pereira, Jorge A. M.;Camara, Jose S.. And the article was included in Microchemical Journal in 2021.HPLC of Formula: 112-14-1 The following contents are mentioned in the article:

Electronic cigarettes (e-cigarettes) have become popular alternatives to traditional tobacco. Despite this, a comprehensive evaluation of their long-term effects and safety for the consumers and the environment is missing. To contribute to filling this gap, headspace solid-phase microextraction combined with gas chromatog.-mass spectrometry (HS-SPME/GC-MS) was employed to establish and compare the volatile fingerprints of traditional tobacco and e-cigarettes. The anal. of traditional tobacco included two popular brands and different parts of the cigarette (solid tobacco, cigarette smoke, cigarette paper and filter). Regarding the e-cigarettes, two e-liquids, with and without nicotine, their main constituents (e-bases) and corresponding vapors, obtained under default vaping (power) conditions, were analyzed. A total of 80 volatile organic compounds (VOCs) were identified in traditional tobacco, of which 14 carbonyl compounds, 9 benzene derivatives, 9 Et esters and 9 hydrocarbons. Slight differences in the volatile profile of cigarette paper and filter between the two brands were also detected, showing that exogenous components of tobacco influence the flavor and harmfulness perceived by the smokers. In turn, 92 VOCs were identified in e-cigarettes, including 31 Et esters, 18 alcs. and 10 hydrocarbons. No VOCs with potentially toxic or harmful effects were identified in the vapor of Do It Yourself (DIY) liquids and Premium samples. Therefore, taking into consideration the volatile compositions obtained for smoking and vaping procedures under normal conditions of operation and using certified e-liquid mixtures, the e-cigarettes analyzed seemed to constitute a valid and less harmful alternative to traditional tobacco for smokers, second-hand smokers and the environment. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1HPLC of Formula: 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 112-14-1

Bioderivatization as a concept for renewable production of chemicals that are toxic or poorly soluble in the liquid phase was written by Sattayawat, Pachara;Yunus, Ian Sofian;Jones, Patrik R.. And the article was included in Proceedings of the National Academy of Sciences of the United States of America in 2020.HPLC of Formula: 112-14-1 The following contents are mentioned in the article:

Bio-based production technologies may complement or replace petroleum-based production of chems., but they face a number of tech. challenges, including product toxicity and/or water insolubility Plants and microorganisms naturally biosynthesize chems. that often are converted into derivatives with reduced toxicity or enhanced solubility Inspired by this principle, we propose a bioderivatization strategy for biotechnol. chems. production, defined as purposeful biochem. derivatization of intended target mols. As proof of principle, the effects of hydrophobic (e.g., esterification) and hydrophilic (e.g., glycosylation) bioderivatization strategies on the biosynthesis of a relatively toxic and poorly soluble chem., 1-octanol, were evaluated in Escherichia coli and Synechocystis sp. PCC 6803. The 1-octanol pathway was first optimized to reach product titers at which the host displayed symptoms of toxicity. Solvent overlay used to capture volatile products partially masked product toxicity. Regardless of whether solvent overlay was used, most strains with bioderivatization had a higher molar product titer and product yield, as well as improved cellular growth and glucose consumption, compared with strains without bioderivatization. The pos. effect on bioprodn. was observed with both the hydrophobic and hydrophilic strategies. Interestingly, in several combinations of genotype/induction strength, bioderivatization had a pos. effect on productivity without any apparent effect on growth. We attribute this to enhanced product solubility in the aqueous or solvent fraction of the bioreactor liquid phase (depending on the derivative and medium used), with consequent enhanced product removal. Overall, under most conditions, a benefit of bioprodn. was observed, and the bioderivatization strategy could be considered for other similar chems. as well. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1HPLC of Formula: 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids.

Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.HPLC of Formula: 112-14-1

On sample preparation methods for fermented beverage VOCs profiling by GCxGC-TOFMS was written by Zhang, Penghan;Carlin, Silvia;Lotti, Cesare;Mattivi, Fulvio;Vrhovsek, Urska. And the article was included in Metabolomics in 2020.COA of Formula: C10H20O2 The following contents are mentioned in the article:

Aromas and tastes have crucial influences on the quality of fermented beverages. The determination of aromatic compounds requires global non-targeted profiling of the volatile organic compounds (VOCs) in the beverages. However, exptl. VOC profiling result depends on the chosen VOC collection method. This study aims to observe the impact of using different sample preparation techniques [dynamic headspace (DHS), vortex-assisted liquid-liquid microextraction (VALLME), multiple stir bar sorptive extraction (mSBSE), solid phase extraction (SPE), and solid phase micro-extraction (SPME)] to figure out the most suitable sample preparation protocol for profiling the VOCs from fermented beverages. Five common sample preparation methods were studied with beer, cider, red wine, and white wine samples. After the sample preparation, collected VOCs were analyzed by two-dimensional gas chromatog. coupled with time of flight mass spectrometry (GCxGC-TOFMS). GCxGC oven parameters can be optimized with the Box-Behnken surface response model and response measure on peak dispersion. Due to the unavoidable column and detector saturation during metabolomic anal., errors may happen during mass spectrum construction. Profiling results obtained with different sample preparation methods show considerable variance. Common findings occupy a small fraction of total annotated VOCs. For known fermentative aromas, best coverage can be reached by using SPME together with SPE for beer, and VALLME for wine and cider. GCxGC-TOFMS is a promising tool for non-targeted profiling on VOCs from fermented beverages. However, a proper data processing protocol is lacking for metabolomic anal. Each sample preparation method has a specific profiling spectrum on VOC profiling. The coverage of the VOC metabolome can be improved by combining complementary methods. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).
