Effect of high hydrostatic pressure and heat sterilization on volatile components in peach juice was written by Xu, Zenghui;Jia, Jianhui;Lu, Xiaolian;Peng, Yijiao;Tian, Xu;Guo, Hong. And the article was included in Shipin Kexue (Beijing, China) in 2012.Formula: C15H22O2 The following contents are mentioned in the article:

In this paper, the effect of high hydrostatic pressure (HHP) and heat sterilization treatments on volatile components in peach juice was investigated. The major volatile components in untreated peach juice were acetic acid, 1-pentanol, 3-methylmethoxy-2-Pr acetate and benzaldehyde. The esters exhibited an increase after HHP treatment, which were acetyl Bu ester and di-Bu phthalate with the content increase by 516.67% and 40.91%, benzaldehyde and nonanal with the content increase by 219.78% and 130.55%. Meanwhile, HHP treatment revealed the occurrence of new compounds such as 3,4-dimethyl-2-hexanone and di-Et phthalate and an obvious loss of alcs. Heat sterilization led to dramatic change of volatile components in peach juice, which exhibited the content decrease of acetyl Bu ester, and complete loss of 1-methoxy-2-Pr acetate, acetic acid, 3-methyl-pentanol and benzyl methanol. However, the increased 2-decen-1-ol (oil flavor) damaged the flavor of peach juice. All of these results indicated that HHP could retain better flavor of peach juice than heat sterilization. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Formula: C15H22O2).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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. 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. Formula: C15H22O2

Corrosion inhibition of carbon steel in HCl solution by aqueous brown onion peel extract was written by Ferreira, K. C. R.;Cordeiro, R. F. B.;Nunes, J. C.;Orofino, H.;Magalhaes, M.;Torres, A. G.;D’Elia, E.. And the article was included in International Journal of Electrochemical Science in 2016.SDS of cas: 5444-75-7 The following contents are mentioned in the article:

The effect of aqueous brown onion peel extract on the corrosion process of carbon steel in 1 mol L-1 HCl was examined The electrochem. results, including the displacement of the corrosion potential and the inhibitory action in both anodic and cathodic polarization curves showed that the examined extract acted as mixed-type inhibitor. The results of the electrochem. impedance measurements showed that the Rct values increased in the presence of inhibitor reaching 94% of inhibition efficiency in the presence of 300 mg L-1 of the extract The inhibition efficiency of C-steel in 1 mol L-1 HCl increased as the temperature increased and the apparent activation energy (Ea) of C-steel dissolution decreased in the presence of the extract, which suggest a strong chemisorptive bond between the components present in the onion extract and the metal surface. The extract anal. showed few volatile compounds with 3(2H)-Furanone, 2-hexyl-5-methyl- as the major volatile compound and a nitrogenous base (5-octadecyl-pyrimidine-2,4,6-trione) which may play an important role in the inhibition process. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7SDS of cas: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.SDS of cas: 5444-75-7

Striking changes in volatile profiles at sub-zero temperatures during over-ripening of ‘Beibinghong’ grapes in Northeastern China was written by Lan, Yi-Bin;Qian, Xu;Yang, Zhong-Jun;Xiang, Xiao-Feng;Yang, Wei-Xi;Liu, Tao;Zhu, Bao-Qing;Pan, Qiu-Hong;Duan, Chang-Qing. And the article was included in Food Chemistry in 2016.SDS of cas: 5444-75-7 The following contents are mentioned in the article:

The evolution of free and glycosidically bound volatile compounds in ‘Beibinghong’ (Vitis vinifera × Vitis amurensis) grape berries throughout on-vine over-ripening and freezing processes was studied in two vintages. The aroma profiles of ‘Beibinghong’ icewine berries were characterized by C6 compounds, higher alcs. and terpenoids in free fractions and carbonyl compounds, higher alcs., C6 alcs. and terpenoids in bound fractions. With regard to free volatile compounds, there was a decrease in the concentration of C6 compounds, terpenols and norisoprenoids and an increase of terpene oxides during over-ripening process. A striking alteration of volatile profile occurred at sub-zero temperatures, particularly for the free fractions such as C6 alcs., higher alcs. and oxidative terpene derivatives These changes were attributed to a series of reactions (biotransformation, oxidation and anaerobic metabolism) induced by water loss and especially freeze-thaw cycles. PCA revealed temperature and rainfall affected the accumulation of volatile compounds during over-ripening processes. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7SDS of cas: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics.

Film-forming aid selection to optimize performance and minimize volatile organic content was written by Strepka, Arron M.;Arendt, William D.;Joshi, Makarand. And the article was included in Proceedings of the International Waterborne, High-Solids, and Powder Coatings Symposium in 2007.Application of 5444-75-7 The following contents are mentioned in the article:

Solvents and highly volatile coalescing aids have traditionally been utilized in waterborne coatings applications to assist in the formation of a continuous film. These materials behave like temporary plasticizers. They soften the polymer long enough to allow coalescence and later evaporate from the coating, leaving behind a durable film. While these materials are effective as film formers, they also contribute significantly to the volatile organic content (VOC) of the coating formulation. More permanent film formation aids are significantly less volatile and can be utilized to promote coalescence. The purpose of this paper is to demonstrate the benefits of incorporating less volatile film-forming aids to lower total formulary VOC. Traditional and new film-formation aid technologies have been evaluated in architectural and industrial waterborne coating formulations to demonstrate advantages. Volatility, low temperature coalescence, freeze thaw stability, blocking resistance, hardness, application and other coating properties are utilized to demonstrate the advantages of this strategy. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Application of 5444-75-7).

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

The esterification of benzoic acid with n-hexanol, n-octanol, 2-ethylhexanol and n-decanol was investigated in detail. An anal. of the reaction kinetics of esterification in the presence of different com. available chem. catalysts was carried out. The effects of catalyst type and loading on the reaction rate were studied. Although the considered reaction is bimol., it showed a first-order behavior, and a linear dependence with respect to the catalyst concentration was observed Hence, a new approach is presented to describe the reaction kinetics accurately over a wide range. The application of biotechnol. synthesis applying different enzymes as catalysts offers an interesting alternative besides chem. synthesis. Especially an esterase from Bacillus subtilis immobilized on Sepabeads EC-EP showed high stability and was applied for 2 days in the synthesis of hexyl benzoate. Nevertheless, the chem. reaction route remains superior with respect to the catalyst activities under the applied conditions, which were 25 kU/g for the chem. reaction and 0.7 kU/g for the best enzymic conversion.

Biodestruction of Phthalic Acid Esters by White Rot Fungi was written by Savinova, O. S.;Shabaev, A. V.;Glazunova, O. A.;Eremin, S. A.;Fedorova, T. V.. And the article was included in Applied Biochemistry and Microbiology in 2022.Reference of 5444-75-7 The following contents are mentioned in the article:

The ability of white rot fungi from different ecophysiol. groups (primary wood-destroying saprotroph Trametes hirsuta, secondary wood-destroying saprotroph Steccherinum ochraceum, litter saprotroph Crucibulum laeve, and humic saprotroph Agrocybe praecox) to degrade phthalic acid esters (PAEs) was studied. It was shown that diethylhexyl phthalate (DEHP) with longer and branched hydrocarbon chains was more rapidly biodegraded by wood-destroying saprotrophs such as T. hirsuta and S. ochraceum, with an efficiency of more than 99%. Di-Bu phthalate (DBP), which is less hydrophobic with shorter hydrocarbon units, was most efficiently transformed by the litter saprotroph C. laeve (up to 96.5%). Di-Et phthalate (DEP) proved to be the most toxic to all fungi. T. hirsuta showed the greatest resistance to elevated DEP concentrations in the medium. It has been shown that fungi destroy PAEs with the formation of various metabolites, depending on the composition of the multienzyme complex of the fungus. Among the secondary metabolites, ionol, an antioxidant formed by fungi when PAEs is added to the medium, was found. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Reference of 5444-75-7).
