High - purity glycerol monolaurate was obtained by hydrolytic ring - opening of glycidyl laurate and freezing crystallization, which catalyzed by non - precious metal inorganic salts. The preparation conditions of glycerol monolaurate were optimized as follows： with acetonitrile as solvent, and CuCI2 as catalyst, dosage of CuCl2 8% （ based on the mole of glycerol monolaurate）, reaction time 24 h. Furthermore, the method was applied to prepare glycerol monopalmitate and glycerol monostearate, and these products were characterized by FT- IR...
