And the article was included in Inzynieria Chemiczna i Procesowa in 2002.Safety of 2-Ethylhexyl benzoate The following contents are mentioned in the article:

The kinetics anal. of the esterification of benzoic acid with n-octyl and isooctyl alcs. in the presence of phosphotungstic acid as a catalyst, in an exptl. isothermal semibatch reactor was studied. The reaction appears to be of the first order with respect to benzoic acid and does not depend on the concentration of octyl alcs. The kinetic parameters were determined This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Safety of 2-Ethylhexyl benzoate).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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 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.

Modifications of Kyoho grape berry quality under long-term NaCl treatment was written by Li, Xiao-Ling;Wang, Chun-Rong;Li, Xiao-Yang;Yao, Yu-Xin;Hao, Yu-Jin. And the article was included in Food Chemistry in 2013.Electric Literature of C15H22O2 The following contents are mentioned in the article:

Different concentrations of a sodium chloride spray were applied to the grapevine cultivar Kyoho to determine the effects of salinity on berry quality. The fruit’s fresh weight, relative water content, hardness and titratable acid were gradually enhanced with increased salt concentrations Anthocyanin and soluble solids increased after treatment with moderate salinity (20 and 60 mM); however, the results were reversed under high salinity (100 and 150 mM). The soluble sugars glucose, fructose and sucrose increased after treatment with moderate salinity, whereas glucose and fructose declined under high salinity. For the six organic acids tested, their total levels were elevated by salinity, which increased the production of tartaric and malic acids. The aroma of the berry was extremely sensitive to salinity and showed a considerable decline in abundance and variety at 20 mM NaCl. In summary, moderate salinity enhanced the overall berry quality, but decreased the aroma quality, whereas high salinity decreased the berry quality. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Electric Literature of C15H22O2).

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. 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.Electric Literature of C15H22O2

Infant Exposure to Emissions of Volatile Organic Compounds from Crib Mattresses was written by Boor, Brandon E.;Jarnstrom, Helena;Novoselac, Atila;Xu, Ying. And the article was included in Environmental Science & Technology in 2014.HPLC of Formula: 5444-75-7 The following contents are mentioned in the article:

Infants spend most of their time sleeping and are likely to be exposed to elevated concentrations of chems. released from crib mattresses. Small-scale chamber experiments were conducted to determine area-specific emission rates (SER) of volatile organic compounds (VOC in 20 new and used crib mattresses). All mattress samples emitted VOC; mean values of total VOC (TVOC) SER were 56 μg/m²-h at 23° and 139 μg/m²h at 36°. TVOC SER were greater for new vs. used mattresses and were affected by type of foam material and a mattress cover layer. A variety of VOC were identified; polyurethane foam released a greater diversity of VOC than polyester foam. Large-scale chamber experiments were conducted with an infant thermal manikin. Sampled TVOC concentrations in the breathing zone and interior pore air of crib mattress foam were greater than bulk room air by factors of 1.8-2.4 and 7.5-21, resp. Results suggested crib mattresses are an important VOC source, and infant VOC exposure is possibly elevated in sleep micro-environments. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7HPLC of Formula: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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 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.HPLC of Formula: 5444-75-7

Recommended Correlations for the Surface Tension of Aromatic, Polyfunctional, and Glyceride Esters was written by Mulero, A.;Cachadina, I.;Vegas, A.. And the article was included in Journal of Physical and Chemical Reference Data in 2022.COA of Formula: C15H22O2 The following contents are mentioned in the article:

Surface tension values for 79 esters, including aromatics, polyfunctional, and glycerides, have been compiled from databases, books, and papers in the literature. The data have been carefully screened, and finally, 1517 values were selected. Each fluid dataset has been fitted with the Guggenheim-Katayama correlation with two or four adjustable parameters. Recommended correlations are proposed for each ester, providing mean absolute deviations below 0.50 mN/m for 77 of them, mean absolute percentage deviations below 1.7% for 76 of them, and percentage deviations below 10%, except for four data out of the 59 selected for tricaprylin. The highest deviations found are due to the disagreement between the data obtained from different sources and not to an inadequate math. form of the correlation model. These correlations are added to the collection of those previously proposed for different fluids, including common substances, alcs., refrigerants, organic acids, n-alkanes, and 80 other esters.

And the article was included in CyTA–Journal of Food in 2015.Recommanded Product: 5444-75-7 The following contents are mentioned in the article:

The profile of volatiles in squids was characterized using simultaneous distillation-extraction coupled with comprehensive two-dimensional gas chromatog. (GC) and Time-of-Flight mass spectrometry (GC×GC-TOFMS). GC×GC-TOFMS improved the resolution and separation efficiency of the compounds; it not only separated the 52 compounds that co-elute in conventional GC-MS, but also allowed the identification of compounds that were not previously detected (e.g. 2-Octanol). The total contents of volatiles detected by GC×GC-TOFM were about 2.5-fold higher than those analyzed by GC-MS. Among 184 volatiles identified by GC×GC-TOFMS, 119 compounds were reported for the first time in squids, compared with the GC-MS data available in the literature. These volatile classes included aromatic hydrocarbons (39), aliphatic hydrocarbons (22), esters (21), aldehydes (20), alcs. (19), sulfo compounds (18), nitrogenous compounds (17), ketones (14), acids (6), furans (5) and phenols (3).

Overheat diagnosis of power cable based on gas sensors: Device/material exploration was written by Liu, Yang;Geyik, Ugur;Kobald, Arne;Yang, Aijun;Wang, Xiaohua;Weimar, Udo;Rong, Mingzhe;Barsan, N.. And the article was included in Sensors and Actuators, B: Chemical in 2022.Synthetic Route of C15H22O2 The following contents are mentioned in the article:

A review. Monitoring the gas composition around power cables using gas sensors is a promising method for detecting their overheating. In this paper we screened the sensing performance in dry and humid conditions of a variety of com. and homemade sensors. The target gases were 2-Ethylhexanol (2-EH), Dioctyl terephthalate (DOTP), and Benzene; they are the main gases evaporated from overheated polyvinyl chloride (PVC), which is the material of choice for the external insulation of power cables. We found that the tested sensors show different sensing performances to the three target gases, generally with a fast response and slow recovery, the latter especially for 2-EH and DOTP. We also found that the responses to DOTP and 2-EH are correlated and, generally, larger than the ones to benzene. We also showed that by combining the sensors into a sensor array and applying PCA it is possible to distinguish between 2-EH and DOTP, on the one hand, and benzene, on the other hand. However, a more refined pattern recognition method is needed to distinguish between 2-EH and DOTP. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Synthetic Route of C15H22O2).
