Title: Catalytic Synthesis of Ethyl Cinnamate with Sodium Bisulfate
Abstract: Ethyl Cinnamate was synthesized by the esterification of ethyl alcohol with cinnamic acid in the presence of sodium bisulfate monohydrate.The results obtained showed that the sodium bisulfate monohydrate consisted of a fairly high catalytic activity of the esterification reaction.The effects of cinnamic acid and ethyl alcohol molar ratio,the amount of sodium bisulfate monohydrate catalyst applied,and the time of reacting on the yield of ethyl cinnamate have been surveyed.In the chemical reaction of the typical condition,the ester yield which was synthesized reache 97.1% (the molar ratio of cinnamic acid/ethyl alcohol / sodium bisulfate=1:19:0.51,refluxing 3h).Sodium bisulfate monohydrate catalyst can be easily recovered and reused.
