| Abstract: | In this paper,glycollide was synthesized,while ultrasound was used to strengthen the reaction.And the influence of ultrasound on the yield and purity during the reaction were studied.In this study,hloroacetic acid was applied as raw materials to synthesize hydroxyl ethanoic acid.Then this thesis synthesizes glycollide successfully by using the method of reduce pressure and dehydration,time of reaction,stannous octoate was used as catalyst.The author observes and investigates the amount of catalyst,the tempe... |
