  • Regioselective synthesis of 1,3-disubstituted glycerides
    Patent number: 5137660
    Abstract: A process for the selective esterification of glycerol and 1-glyceryl derivatives to 1,3-disubstituted glycerides is disclosed. This process uses a water immiscible solvent, either a hydrocarbon or halogenated hydrocarbon, a 1,3-lipase and fatty acid anhydrides. This reaction mixture selectively esterifies the primary alcohol groups of glycerol or glycerol derivatives. The preferred derivatives of glycerol are alkyl ethers, alkyl phosphates, phospholipids, alkyl and diaklyl phosphates, and sugar glycosides.
