Abstract: The retention and sorption enthalpy characteristics of 38 pentaerythritol esters of C2–C8 carboxylic acids of different structures were determined by gas-liquid chromatography on a nonpolar phase in the temperature range 433.2–563.2 K. The molecular structure was shown to affect the temperature dependence of the retention indices of the esters. The average change in the sorption enthalpy of pentaerythritol tetraesters per CH2 group is lower in magnitude than the similar contribution for normal alkanes. The excess mixing enthalpy at 298.2 K was evaluated for four fully substituted pentaerythritol esters.

, (2008/06/13)
The present invention relates to a fatty acid ester of an etherified polyhydric alcohol represented by the following general formula (1), a production process thereof, a cosmetic composition comprising this compound, and a production process of an etherified polyhydric alcohol via the ester. (G: a residue formed by removing H atoms of all the OH groups of a polyhydric alcohol having at least three OH groups, A: --CH2 CH(OH)R or --CHRCH2 OH, R1 : R1a or --CH2 OR1a (R1a : C1 -C36 alkyl or alkenyl group), B: H or C1 -C11 acyl group, x+y: the number of the OH groups of G, x≥1, y≥1, and at least one of y groups B: alkanoyl group). The compound (1) is not only useful as an intermediate for the production of an etherified polyhydric alcohol, but also excellent per se in the performance as a cosmetic base, emulsifier, lubricant, oily component and the like.
