Method of preparing esters of glycerol and polyglycerols and C5- C9 monocarboxylic fatty acids

摘要

The method of preparing esters of glycerol and polyglycerols with monocarboxylic fatty acids having from 5 to 9 carbon atoms consists in that glycerol and polyglycerols are reacted with monocarboxylic fatty acids, having from 5 to 9 carbon atoms at a temperature of 140°- 210° C with continuous distillation of water that is present in the reaction zone. Glycerol and polyglycerols are introduced into the reaction as part of still bottoms of the process of distillation of synthetic glycerol obtained by the chlorine method, and containing sodium hydroxide and sodium chloride. The resultant reaction mixture contains the end product, which is isolated by any known method.
