Carbon capture, utilization and sequestration technol. is effective for carbon emissions reduction The development of new absorbent seems to be one of the core components of carbon capture technol. In this paper, three esters, Me heptanoate, Et hexanoate and Me benzoate, were selected to determine CO₂ solubilities at different temperatures ranging from 293.15 to 333.15 K, and pressures up to 1.2 MPa, using the isothermal synthesis method. The results showed that the absorbent with the straight-chain alkyl group was more effective for improving CO₂ absorption capacity than the benzene group. Et hexanoate showed slightly higher CO₂ solubilities than its isomer Me heptanoate. In addition, Henry’s constant and thermodn. properties such as solution enthalpy, solution entropy, solution Gibbs energy and solution heat capacity, were determined based on the measured data since the above properties are essential for designing an absorption process. Et hexanoate is superior to the other two selected absorbents, common solvents, com. absorbents, some phys. absorbents, some polymeric absorbents and some ionic liquids, which indicates that it has potential value for CO₂ capture technol. However, further studies will be necessary to assess the reliability of its industrial application. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Computed Properties of C8H16O2).

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. 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.Computed Properties of C8H16O2

Application of lactic acid bacteria for improving the quality of reduced-salt dry fermented sausage: Texture, color, and flavor profiles was written by Hu, Yingying;Li, Yongjie;Li, Xiang-ao;Zhang, Hongwei;Chen, Qian;Kong, Baohua. And the article was included in LWT–Food Science and Technology in 2022.Application In Synthesis of Methyl heptanoate The following contents are mentioned in the article:

The traditional dry sausage is highly appreciated in China because of its unique quality characteristics, but it contains high salt content. Hence, this study aimed to evaluate the effects of lactic acid bacteria (LAB) comprising Lactobacillus sakei (LS), Lactobacillus curvatus (LC), Lactobacillus plantarum (LP), and Weissella hellenica (WH) on the quality attributes of the reduced-salt dry fermented sausages. The results indicated that the LP sausage showed higher (P < 0.05) shear force value compared to the other sausages, while the LP, LC, and WH sausages had higher (P < 0.05) lightness values than the control sausages. Seventy-six volatile compounds were detected, and nine compounds were identified as the key differential volatile compounds among the sausages based on partial least squares discriminant anal. Clustering anal. of electronic nose results corresponded well to the volatile compound results. The sensory evaluation confirmed that the inoculation with LC and LP had a pos. impact on the aroma, color, and hardness attributes of the reduced-salt sausages. Besides, partial least squares regression anal. further indicated that L. curvatus and L. plantarum could be used as the potential starter cultures to manufacture reduced-salt dry fermented sausage having improved texture, color, and flavor. 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. 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.Application In Synthesis of Methyl heptanoate

Proton affinities and ion enthalpies was written by Holmes, John L.;van Huizen, Nick A.;Burgers, Peter C.. And the article was included in European Journal of Mass Spectrometry in 2017.SDS of cas: 106-73-0 The following contents are mentioned in the article:

Proton affinities of a number of alkyl acetates (CH₃-C(=O)-OR) and of Me alkanoates (R-C(=O)-OCH₃, R=H, alkyl) have been assembled from the literature or measured using the kinetic method. It was observed that the proton affinities for the isomeric species CH₃-C(=O)-OR and R-C(=O)-OCH₃ are almost identical, an unexpected result as the charge in these protonated ester mols. is largely at the keto carbon atom and so this site should be more sensitive to alkyl substitution. Anal. of the data, including those from lone pair ionisation and core-electron ionisation experiments available from the literature, indicate that after protonation, extensive charge relaxation (or polarisation) takes place (as is also the case, according to the literature, after core-electron ionisation). By contrast, after lone pair ionisation, which results in radical cations, such relaxation processes are relatively less extensive. As a consequence, changes in ion enthalpies of these protonated mols. follow more closely the changes in neutral enthalpies, compared with changes in enthalpies of the corresponding radical cations, formed by electron detachment. Preliminary analyses of published energetic data indicate that the above finding for organic esters may well be another example of a more general phenomenon. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0SDS of cas: 106-73-0).

Methyl heptanoate (cas: 106-73-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics.

A novel column modification approach for capillary gas chromatography: combination with a triptycene-based stationary phase achieves high separation performance and inertness was written by He, Yongrui;Qi, Meiling. And the article was included in New Journal of Chemistry in 2021.Application In Synthesis of Methyl heptanoate The following contents are mentioned in the article:

This work presents a novel strategy for the construction of a capillary column with high resolving performance and inertness for gas chromatog. (GC) anal. by combining the proposed surface modification with a selective stationary phase. Through the modified biphasic sol-gel reaction inside a capillary GC column, porous modification was made on the capillary surface (PM capillary) prior to coating with a stationary phase. Herein, we designed and synthesized a new triptycene-based stationary phase (TPPG) for the study. Using the proposed strategy, the PM-TPPG column was fabricated with a column efficiency of 4950 plates per m determined by n-dodecane at 120°C and then investigated for its separation performance, inertness, repeatability, loadability and thermal stability. As demonstrated, the PM-TPPG column showed distinct advantages in these aspects over two reference columns (TPPG column and com. PEG column). Particularly, the PM-TPPG column well resolved all the components in the Grob mixture and exhibited distinctly improved peak shapes for carboxylic acids and heterocyclic bases. Moreover, it exhibited excellent repeatability and reproducibility and higher column loadability than the two reference columns. Its applications to purity monitoring of chem. products demonstrate its good potential for practical GC anal.

Among condiments, paprika is one of the most important ones used both for flavouring and improving other sensorial properties of foods. Because of their agricultural origin, spices are often naturally contaminated with various bacteria due to poor sanitation during growth, harvest, drying, and storage. In this study different decontamination methods were compared regarding microbial decontamination efficacy and maintaining the biochem., aroma and color properties. Irradiation and steaming, were found to be highly effective for microbial decontamination of spice paprika powders. Only slight changes were detected due to the decontamination treatment for bioactive component content, however significant changes were observed in the levels of volatile aroma compounds Alternative decontamination methods, such as microwave heating alone and combined with re-wetting and intensive mixing, or radio-frequency heat treatment alone were also performed to evaluate the effect of these treatments. These methods were found to be less effective in the reduction of the mesophilic aerobic total bacterial counts, while the levels of molds were significantly reduced, if the samples were held for 10 min at the given incubation temperatures The treatments did not significantly affect chem. compositional parameters, but sample color was appeared adversely affected.

Flavor differences between commercial and traditional soybean paste was written by Zhang, Xiao;Wei, Jianping;Zhao, Shiyu;Jia, Hang;Guo, Chunfeng;Wang, Zhouli;Gao, Zhenpeng;Yue, Tianli;Yuan, Yahong. And the article was included in LWT–Food Science and Technology in 2021.SDS of cas: 106-73-0 The following contents are mentioned in the article:

Fermented soybean paste is becoming popular worldwide due to its umami taste and characteristic aroma. To elucidate the relationships between the odorants and the flavor differences of com. soybean paste (CSP) and traditional soybean paste (TSP), 49 samples (13 CSP, 36 TSP) were collected and evaluated in this research. The aroma-active compounds of CSP and TSP samples were analyzed by electronic nose, gas chromatog.-olfactometry-mass spectrometry combined with aroma extract dilution anal., and the key aroma compounds were identified by calculation of the detection rates and odor activity values. Following characterization, 23 and 19 odorants were identified as key aroma compounds contributing to flavor differences in CSP and TSP samples, resp. Significant differences were observed for the acids, alcs., aldehydes, terpenes, and sulfur-containing compounds The results showed that the flavor differences of the samples were more resulted from the concentrations of the key aroma compounds rather than their compositions and those differences mainly came from the long maturation period of TSP samples and heating process of CSP samples. Further, orthogonal partial least squares discrimination anal. revealed that the key aroma compounds identified in this research could explain the flavor differences of com. and traditional soybean pastes. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0SDS of cas: 106-73-0).

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

BACKGROUND : Borojoa sorbilis (Ducke) is an Amazonian species with edible fruits that are widely consumed by the local population, but little studied and not yet economically explored. Thus the aim of this study was to describe the chem. composition, volatile compounds, nutritional aspects and antioxidant activity of the fruit pulp and peel of B. sorbilis. RESULTS : Headspace solid-phase microextraction, using polydimethylsiloxane-divinylbenzene (PDMS-DVB) fiber, resulted in the identification of 59 substances in the pulp and peel of B. sorbilis fruits after anal. of the chromatograms obtained by gas chromatog.-mass spectrometry using polar and nonpolar columns. Esters were the most abundant. Moisture, lipids, protein, dietary fiber, ash, carbohydrate, total energy value, titratable acid, soluble solids and pH were measured. Protein amount, fat content and antioxidant activity were low in both pulp and peel. Carbohydrate content was 179.2 and 134.9 g kg^-1 in pulp and peel, resp. CONCLUSION : This is the first report on the chem. characteristics, flavor and nutritional aspects of B. sorbilis fruit, which is essential to its economic exploitation. The high energy value associated with the carbohydrate content, plus the low fat content, contribute to a possible use of B. sorbilis fruits as a food supplement. © 2018 Society of Chem. Industry.

The volatile compounds found in melons (Cucumis melo L.) obtained from three cultivars [Jiashi (JS), Xizhoumi17 (XZM) and Minqin (MQ)] were comprehensively analyzed by gas chromatog.-olfactometry (GC-O), gas chromatog.-mass spectrometry (GC-MS), and GC-flame photometric detection (GC-FPD). The result showed that 46, 45 and 69 volatile compounds were detected in XZM, JS and MQ samples by GC-MS, resp. Besides, 6, 8 and 9 sulfur compounds were detected by GC-FPD, resp. Di-Me sulfide, 1-propanethiol, 3-mercapto-3methylbutanol, 3-methyl-2-buten-1-thiol were detected for the first time in melon. 25 key aroma compounds were identified in MQ muskmelon by omission tests, among which (Z)-6-nonenal, (Z)-6-nonen-1-ol, 3-methylbutanal, 2-methylbutyl acetate, hexanal and Me thioacetate were particularly important. The interaction between three aroma compounds containing nine-carbon straight-chain structure and five thioesters in MQ muskmelon was studied by comparing their olfactory threshold and OAV values. Among the 18 binary mixtures, 8 mixtures showed a synergistic effect, 2 mixtures presented an additive effect, 2 mixtures showed no interaction, 6 mixtures exhibited a masking effect. There is a synergistic effect between (Z)-6-nonenal, (Z)-6-nonen-1-ol and (E, Z)-3,6-nonadien-1-ol, the aroma intensity of the mixture can be predicted by modified vector model.

Me ester is the main component of biodiesel, which plays a crucial role in constructing chem. kinetic models for the combustion. The carbon chain length and the degree of unsaturation have a significant influence on the mol. properties and reactivity of Me esters. In this study, to explore the difference in chain length and reactive sites of Me esters, the quantum chem. approach is used to examine the chem. reaction sites of Me butyrate, Me crotonate, Me heptanoate, and Me enanthate. Based on d. functional theory, the structure of the four Me ester mols. is optimized under the M06-2X method, and the global reactivity (including mol. electrostatic surface potential, frontier MO) and local reactivity (including Fukui function, charge, and natural bond orbital) are analyzed. At the same time, the visualization results are also obtained. The results show that the reactive sites of saturated Me ester occur in the structure of the ester group, and the reactive sites of Me crotonate occur on the ester group and the double bond. Further, the reactivity of Me crotonate is stronger than that of the three saturated Me esters. As the carbon chain grows, the reactivity of saturated Me esters gradually increases. Overall, the results provide a theor. basis for revealing the different structural properties of Me esters and subsequent chem. kinetic calculations This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Recommanded Product: Methyl heptanoate).

In present study, surface light scattering (SLS) was used for the simultaneous determination of liquid surface tension and kinematic viscosity of twelve fatty acid esters, including six Me esters (FAMEs) and six Et esters (FAEEs). The SLS apparatus was firstly checked with a reference fluid n-dodecane, and a good agreement of our data from SLS with those from literatures could be found. By utilizing this apparatus, both properties were investigated in the temperature ranges between (298 and 448) K for all substances with an exception of Me myristate and Et myristate covering the temperatures between (323 and 448) K due to their high m.ps. Addnl., the liquid d. and refractive index were determined by an Anton Paar U-tube densimeter between (293 and 453) K and a refractometer from (278 to 358) K, resp. The surface tension and viscosity data obtained from the SLS experiment were fitted to the van der Waals type and the reciprocal temperature-dependent polynomial equations, resp. The quadric and linear functions were adopted to correlate the d. and refractive index data, resp. This work improves the data situation for these fatty acid esters especially at elevated temperatures and provides necessary data and models for the crucial thermophys. properties in connection with the design and optimization of the injection system of an internal combustion engine (ICE).
