In this research, co-pyrolysis of sugarcane bagasse and rubber seed oil using zeolite-Y as catalyst was carried out, with the main purpose to study the effect of raw material compositions on chem. composition of liquid fuel produced. For this purpose, the mixture of sugarcane bagasse and rubber seed oil with different mass ratios of bagasse to oil of 1 : 1; 1: 2; 1: 3: and 1: 4 was subjected to pyrolysis at 450° C in the presence of zeolite-Y as catalyst, and the liquid fuels were analyzed by GC-MS. The results show that liquid fuel contains hydrocarbons as main components, with several addnl. components include alcs., esters, ketones, aldehydes, and acids. The liquid fuel produced from the raw material with the ratio of 1 : 3 was found to contain hydrocarbon with the highest relative percentage (87.91%), and consists of gasoline fraction (42.60%), kerosene fraction (43.59%), and residual fraction (1.72%). This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Synthetic Route of C8H16O2).

A novel calix[4]resorcinarene-based ionic liquid (C4RA-2IL) was synthesized, structurally characterized, and statically coated on capillary column as stationary phase for capillary gas chromatog. (GC). The column efficiency of the C4RA-2IL column is 3345 plates m^-1, which are determined by n-dodecane at 120°C. Based on its McReynolds constants, the C4RA-2IL column showed moderate polarity. Particularly, the C4RA-2IL column show high separation performance for a wide range of analytes and some difficult separation of meta/para-isomers. Moreover, it exhibited excellent selectivity for critical aromatic isomers of chloroaniline, bromaniline, iodoaniline, toluidine and xylidine isomers and shows advantageous separation capability over the com. polysiloxane stationary phase. This work presents a promising future of calixarene-based ionic liquid as a new type of stationary phase in GC separations This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Application In Synthesis of Methyl heptanoate).

Methyl heptanoate (cas: 106-73-0) 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. 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.

Methyl heptanoate (cas: 106-73-0) 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. Polyesters are important plastics, with monomers linked by ester moieties. 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.Product Details of 106-73-0

And the article was included in Thermochimica Acta in 2020.Computed Properties of C8H16O2 The following contents are mentioned in the article:

The additive scheme for calculating the solvation enthalpies of aliphatic compounds has been developed for linear mono- and dimethyl-esters. Ester group contribution to the enthalpy of solvation in n-heptane was obtained. Accuracy of the proposed approach for determination of solvation enthalpies of linear mono- and dimethyl-esters was tested by comparison with exptl. solvation enthalpies. In most cases, deviations do not exceed 1 kJ·mol^-1. It was found that the dependence of the solution enthalpies of mono- and dimethyl-esters on the number of carbon atoms in the mol. can be fitted by power function. This dependence and a group-additivity scheme for solvation enthalpy were used for estimation of the enthalpies of phase transitions of mono- and dimethyl-esters. Evaluated values of sublimation, vaporization, and fusion enthalpies at 298.15 K are in good agreement with exptl. data obtained by conventional methods.

Alkylglycerols (AKGs) are bioactive natural compounds that vary by alkyl chain length and degree of unsaturation, and their absolute configuration is 2S. Three AKGs were synthesized in enantiomerically pure form, and were characterized for the 1st time together with 12 other known and naturally occurring AKGs. Their structures were established using ¹H and ¹³C APT NMR with 2D-NMR, ESI-MS, or HRESI-MS and optical rotation data, and they were tested for their antibacterial and antibiofilm activities. Some AKGs showed activity against 5 clin. isolates and Pseudomonas aeruginosa ATCC 15442, with MIC values in the range of 15-125μg/mL. In addition, at half of the MIC, most of the AKGs reduced Staphylococcus aureus biofilm formation in the range of 23-99% and P. aeruginosa ATCC 15442 biofilm formation in the range of 14-64%. The antibiofilm activity of the AKGs assessed in this work had not previously been studied.

The aim of this study was to use gas chromatog.-mass spectrometry (GC-MS) and APCI-MS techniques to detect adulteration in honey. The key volatile compounds in the headspace of the adulterated honey were marked by GC-MS and their representative fragment ions were utilized in scanning honey samples using the real-time APCI-MS system. The PLS models validated using independent data sets resulted in coefficient of the determination (Rp2) of 0.97 and 0.96 and root mean square error in prediction (RMSEP) of 2.62 and 2.45 for the GC-MS and APCI-MS data sets resp. The most efficient volatiles from GC-MS anal. and their corresponding fragment ions m/z from APCI-MS data anal. were then identified and used to develop new PLS models to predict the level of adulteration. The best PLS model gave Rp2 of 0.95 and RMEP of 2.60% in the independent validation set indicating that the model was very accurate in predicting the level of adulteration.

Evaluation of flavor characteristics of bacon smoked with different woodchips by HS-SPME-GC-MS combined with an electronic tongue and electronic nose was written by Du, Hongzhen;Chen, Qian;Liu, Qian;Wang, Yan;Kong, Baohua. And the article was included in Meat Science in 2021.Quality Control of Methyl heptanoate The following contents are mentioned in the article:

This study investigated the effects of different woodchip types (beech, oak, pear, and apple) on the volatile compounds and sensory characteristics of smoked bacon. The volatile compounds were influenced by woodchip types and the total content of ketones and phenols in pear-smoked bacon were higher than in bacon smoked with other woodchips (P < 0.05). The E-tongue combined with E-nose can effectively distinguish the difference in the flavor of bacon smoked with different woodchip types by the signal intensities. Sensory anal. showed that smoking increased bacon′s redness, saltiness, and smoky flavor compared with the control (unsmoked bacon) (P < 0.05) and it had little impact on off-odor (P > 0.05). Correlation anal. showed that the E-nose and E-tongue data were highly correlated with contents of alcs., aldehydes, and ketones. This study revealed that the different smoked materials greatly influenced the flavor and sensory properties of bacon. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Quality Control of Methyl heptanoate).

Methyl heptanoate (cas: 106-73-0) 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. 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.Quality Control of Methyl heptanoate

Observing the On-Site Generation of Excitons and Charges by Low-Temperature Spectroscopy was written by Dou, Fei;Fei, Zhuping;Buchaca-Domingo, Ester;Brosseau, Colin-Nadeau;Leonelli, Richard;Heeney, Martin;Zhang, Xinping. And the article was included in ACS Applied Materials & Interfaces.Reference of 106-73-0 The following contents are mentioned in the article:

Understanding the relation between phase morphol. and phys. processes in polymer blends is the key to the fabrication of reproducible and reliable polymer optoelectronic devices. In this work, taking the advantage of low-temperature spectroscopy, we have observed the on-site generation of excitons and long-lived charges in different phase morphol. polymer/fullerene blends. Probing at 10K, the photo-generated species are localized to where they are generated. We found that the generation of excitons and long-lived charges is highly influenced by the local mol. phase morphol. We further demonstrated that although the influence of phase morphol. is localized to the place that excitons and long-lived charges are generated, this influence can persist over sub-millisecond timescales. Thus, we believe that the fate of excitons and long-lived charges is determined by the location at which they are generated, which can in turn be controlled precisely by mol. phase morphol. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Reference of 106-73-0).
