1,3-Distearoxy acetone and 1,3-dipalmitoxy acetone were prepared by interesterification of the methyl esters of the fatty acids with 1,3-dipropionoxy acetone diethyl mercaptal. The 1,3-diglycerides were obtained by hydrogenation of the ketone group. Allyl tetrahydropyranyl ether was oxidized to 1-tetra-hydropyranyl glycerol which was acetylated and interesterified with methyl esters of fatty acids to produce 1,3-diglycerides.
