Abstract
Disclosed are a method for preparing 1-acyl-3-acetylglycerol in high purity and high yield without a purification process using a column chromatography, and a method for preparing 1,2-diacyl-3-acetylglycerol in high purity and high yield using the same as a key intermediate. The method includes the steps of: forming a reaction mixture including 1-acyl-3-acetyl glycerol of the Formula 1 in the specification by reacting 1-acylglycerol of the Formula 2 in the specification and an acetylating agent; and separating the racemic or optically active 1-acyl-3-acetylglycerol by crystallizing the reaction mixture in a saturated hydrocarbon solvent having 5 to 7 carbon atoms.
