| Abstract: | Since the synthesis of ethyl benzoate is a typical organic experiment,this paper introduces a self-developed reflux-absorption reactor.The effects of reaction time and the amount of the catalyst on the ester yield were investigated with sodium bisulfate monohydrate green catalyst.The results indicate that the improved experiment is characterized by simple devices,easy operations,high yields and a green process. |
