Abstract
Ethyl β-benzoylacrylate was synthesized by one pot method using acetophenone and glyoxylic acid as starting materials.The obtained optimum conditions were n(acetophenone)∶ n(glyoxylic acid)∶ n(ethanol)∶n(catalyst) =1.00∶1.25∶5.07∶0.02,esterification temperature 85 ℃,esterification time 3 h,elimination temperature 115~120 ℃ and elimination time 9 h.Under above conditions,the yield and purity of ethyl 3-benzoylacrylate were 77.74% and 91.07% respectively based on acetophenone.
