In order to evaluate the effects of yeast starter on the quality and flavor profile of Longyan dry white wine, pure fermentation and sequential fermentation of selected Torulaspora delbrueckii and selected Saccharomyces cerevisiae (VL2, DELTA, X5) were performed in industrial-scale fermentation of this work. Compared with pure fermentation, sequential fermentation improved the fermentative aroma concentrations, especially the treatment of T. delbrueckii/DELTA increased the content of Et butyrate, Et caprylate and Et decanoate, which may be related to a strong citrus fruity aroma. Principal component anal. revealed a significant difference in aromatic feature of co-fermentation of T. delbrueckii/DELTA and T. delbrueckii/VL2 from their resp. pure fermentation These may be related to amino acid metabolism and further affected the formation of volatile compounds according to correlation anal. Overall, sequential fermentation using DELTA and T. delbrueckii strengthened the aroma characteristics and improved the complex of wines. It will provide a new strategy to regulate the flavor and improve the quality of Longyan dry white wine. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Reference of 112-14-1).

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. 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.Reference of 112-14-1

Frankincense is a fragrant resin produced by Boswellia species, and has been used for centuries as a perfume, medicine, and incense, and is an important cosmetic and therapeutic product today. A number of studies have been conducted on the resin essential oils, but many have used com. sources outside of the country of origin, leading to potential taxonomic confusion or misidentification. Individual Boswellia papyrifera resin samples were each obtained directly from 11 individual trees in Sudan, hydrodistd., the volatile phytochems. determined by gas chromatog. methods, and the chem. compositions subjected to cluster anal. All samples were very similar, with high levels of octyl acetate (49.5%-81.0%) and octanol (6.5%-13.7%), and varying levels of diterpenoids (6.6%-32.7%). The cluster anal. indicated 3 highly similar groups, defined by (1) relatively higher levels of octyl acetate (58.9%-81.0%), but with low levels of diterpenoids (6.6%-18.6%); (2) relatively lower levels of octyl acetate (49.5%-61.3%), but with a higher proportion of diterpenoids (19.0%-22.8%); and (3) with octyl acetate (51.6%) and diterpenoids (32.7%). This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products 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. 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.Related Products of 112-14-1

A New Protocol for Catalytic Reduction of Alkyl Chlorides Using an Iridium/Bis(benzimidazol-2′-yl)pyridine Catalyst and Triethylsilane was written by Fukuyama, Takahide;Hamada, Yuki;Ryu, Ilhyong. And the article was included in Synthesis in 2021.Application of 112-14-1 The following contents are mentioned in the article:

The reduction of alkyl/aryl chlorides RX (R = n-dodecyl, adamantan-1-yl, naphthalen-1-yl, etc.) using triethylsilane is investigated. Primary, secondary, tertiary, and benzylic C-Cl bonds were effectively converted into C-H bonds using [IrCl(cod)]₂/2,6-bis(benzimidazol-2-yl)pyridine catalyst system. This catalyst system is quite simple since the tridentate N-ligand can be easily prepared in one step from com. available reagents. 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 typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C 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.

Sn-catalyzed mild protocol was reported for ring expansion of peroxyoxindoles to afford a series of substituted 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives In this protocol, authors showed the in-situ conversion of tert-Bu peroxy compounds into peresters with the aid of external esters, which then underwent the ring-expansion process and the incipient carbocation was trapped with the alc. residue generated from the esters. The reaction was also demonstrated in a continuous flow process. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Name: Octyl acetate).

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.

This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Quality Control of Octyl acetate).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Quality Control of Octyl acetate

Amide/Iminium Zwitterionic Catalysts for (Trans)esterification: Application in Biodiesel Synthesis was written by Lam, Ying-Pong;Wang, Xinyan;Tan, Fei;Ng, Wing-Hin;Tse, Ying-Lung Steve;Yeung, Ying-Yeung. And the article was included in ACS Catalysis in 2019.Safety of Octyl acetate The following contents are mentioned in the article:

A class of zwitterionic organocatalysts based on an amide anion/iminium cation charge pair has been developed. The zwitterions are easily prepared by reacting aziridines with aminopyridines. They are catalytically applicable to transesterifications and dehydrative esterifications. Mechanistic studies reveal that the amide anion and iminium cation work synergistically in activating the reaction partners, with the iminium cationic moiety interacting with the carbonyl substrates through nonclassical hydrogen bonding. The reaction can be applied to large-scale synthesis of biodiesel under mild conditions. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Safety of Octyl acetate).

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. 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.Safety of Octyl acetate

Transition-State Expansion: A Quantitative Model for Counterion Effects in Ionic Reactions was written by Han, Junbin;Lu, Zhichao;Hammond, Gerald B.;Xu, Bo. And the article was included in iScience in 2020.Application of 112-14-1 The following contents are mentioned in the article:

Ionic reactions are the most common reactions used in chem. synthesis. In relatively low dielec. constant solvents (e.g., dichloromethane, toluene), ions usually exist as ion pairs. Despite the importance of counterions, a quant. description of how the paired ‘counterion’ affects the reaction kinetic is still elusive. We introduce a general and quant. model, namely transition-state expansion (TSE), that describes how the size of a counterion affects the transition-state structure and the kinetics of an ionic reaction. This model could rationalize the counterion effects in nucleophilic substitutions and gold-catalyzed enyne cycloisomerizations. 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. 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. 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.Application of 112-14-1

A second-generation m-phenolsulfonic acid-formaldehyde resin (PAFR II) catalyst was prepared by condensation polymerization of sodium m-phenolsulfonate and paraformaldehyde in an aqueous H₂SO₄ solution This reusable, robust acid resin catalyst was improved in both catalytic activity and stability, maintaining the characteristics of the previous generation catalyst (p-phenolsulfonic acid-formaldehyde resin). PAFR II was applied in the batchwise and continuous-flow direct esterification without water removal and provided higher product yields in continuous-flow esterification than any other com. ion-exchanged acid catalyst tested. 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 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. 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

Investigation of the Chain Transfer Agent Effect on the Polymerization of Vinylidene Fluoride was written by Stefanichen Monteiro, Igor;Mendez Ecoscia, Ana Carolina;McKenna, Timothy F. L.. And the article was included in Industrial & Engineering Chemistry Research in 2019.COA of Formula: C10H20O2 The following contents are mentioned in the article:

The effect of chain transfer agents (CTAs) Et acetate (EA), octyl acetate (OA), and iso-Pr alc. (IPA) on the rate of polymerization of vinylidene fluoride (VDF) in an emulsion polymerization and in solution polymerization in di-Me carbonate (DMC) initiated by tert-Bu peroxypivalate was investigated. Pressure profiles of the polymerizations were recorded. Solids content and rate of polymerization were calculated by gravimetry; size exclusion chromatog. was utilized to evaluate CTA activity, and the produced polymer microstructures were characterized by ¹H and ¹⁹F NMR spectroscopies. It is proposed that the observed reduction in polymerization rate in both systems is due to degradative chain transfer reactions. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1COA of Formula: C10H20O2).
