Abstract:
      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 CuCl2 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 and ESI-MS, which confirmed the validity of the preparation method.
