| Abstract: | The glycerol acetonide is synthesized with glycerol and acetone.The influence of reaction time,molar ratio of material,catalyst concentration,the choice and ratio of water-removing solvent are investigated.The highest yield（85 %） of glycerol acetonide is obtained under the conditions of molar ratio of glycerol to acetone 1∶3,catalyst concentration 6 %,reaction time 5 h,the optimum water-removing solvent is acetone and its volume ratio to glycerol is 4.5∶1. |
