(1)Use lower alcohol Na or lower alcohol potassium as catalyst, lower alcohol ester of lauric acid and glycerol mixed according to the molar ratio of 3:1, under the condition of 150-170 vacuum reaction 20-40h to obtain glycerol ester of lauric acid crude product;
(2)Use 40-50% of the weight of the crude product of glycerol ester of fatty lauric acid, mass fraction of 4%-10% of the aqueous citric acid to wash fatty acid glycerol ester of crude product once, and then Add 30% -50% of the weight of crude glyceryl laurate 80-100 C hot water, stirred well, static stratification, separation of the upper layer of oil, and then 80-100 C hot water, water wash 3 times, heating and depressurization to remove water;
(3) in the temperature of 130-220 C, the vacuum degree of 0.1-150pa under the conditions of molecular distillation of the product of the said step (2) to get the product of the glyceryl laurate. Glyceryl laurate product.
