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, 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.Product Details of 5444-75-7

High-Resolution 13C NMR Study of Liquid 2-Ethylhexyl Benzoate Confined to Porous Silica Glasses was written by Zhang, Jing;Jonas, Jiri. And the article was included in Journal of Physical Chemistry in 1994.Product Details of 5444-75-7 The following contents are mentioned in the article:

Natural abundance carbon-13 NMR spin-lattice relaxation times, T1, and spin-spin relaxation times, T2, in the model liquid lubricant 2-ethylhexyl benzoate (I), confined to porous silica glasses prepared by the sol-gel process, were measured as a function of pore size at 294 K for pore radius 21-80 Å. In agreement with earlier results for other polar liquids, the two-state fast-exchange model was valid for the spin-relaxation data for I (i.e., the 1/T1 rates scale as 1/R with pore radius R). The anal. of the 1/T1 data for each carbon in confined I in terms of the two-state fast-exchange model allowed the calculation of the relaxation rates 1/T1S for each carbon of I in the surface layer. The comparison of 1/T1S for each carbon with the 1/T1 values for individual carbons in bulk I provided information on motional dynamics of I at the liquid/surface interface. The exptl. 13C spin-spin relaxation rates 1/T2 obey the quadratic power law 1/R2 for confined I, confirming that at low frequency, the pure geometric confinement effects dominate over surface interaction effects. Addnl. information on the I surface interactions was obtained by carrying out the NMR experiments with surface-modified silica glasses. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Product Details of 5444-75-7).
