GLYCERIDE SYNTHESES: II. PREPARATION OF SYMMETRICAL SATURATED MONOACID DIGLYCERIDES FROM 2-O-BENZYLGLYCEROL

Abstract

A direct preparation of symmetrical saturated monoacid diglycerides is described. The synthesis involves the preparation of 2-O-benzylglycerol, acetylation, interesterification with either methyl stearate or methyl palmitate, and hydrogenolysis to yield the desired 1,3-diglyceride. The melting points of the symmetrical diglycerides are slightly higher than those obtained previously by other methods of synthesis which involve a 1,2 to 1,3 shift of acyl groups.
