Process for preparing boric esters of glycerol fatty acid esters

摘要

Preparation of boric esters of glycerol fatty acid esters which comprises reacting triglycerides such as natural oils and fats with glycerol and boric acid in specific ratios. 3 mols of boric acid, 1 to 2 mols of at least one long-chain fatty acid triglyceride, and 4 to 5 mols of glycerol are interacted under neutral or acidic conditions at a temperature of 240 DEG -280 DEG C. According to the invention, boric esters can be obtained substantially in quantitative and good yield because of a small loss of reaction.
