Synthesis of Glycerol Triacetate Catalyzed by SnCl_4·5H_2O-C

The optimun technological conditions were studied on the synthesis of glycerol triacetate by the reaction of glacial acetic acid and glycerol with SnCl 4·5H 2O/C as catalyst.The results showed that the yield was over 96% when glycerol:glacial acetic acid=1∶4(molar ratio),the amount of catalyst was 1.5g/mol of glycerol,the amount of toluene was 25mL,and the reaction time was 5h.This process has many advantages such as higher yield,simple procedure,shorter reaction period,non corrosive,non pollution,etc.
