Abstract:

Product compn. of polyglycerol esters, prepd. from a direct alk. polymn. of glycerol followed by esterification with stearic or oleic acids, was studied. The internal product compn., as analyzed by high performance liq. chromatog. (HPLC), shows clearly that in contradiction to what has been published recently, the fatty acid radicals are not distributed at random among all available hydroxyl groups, and thus, any theor. calcn. on the product compn. could not be correct. The product compn. of the crude material indicates clearly that the internal positions (secondary hydroxyls) of the glycerol polymer are esterified with greater difficulty than the primary hydroxyl groups.
