Abstract
Ethyl β-benzoylacrylate was synthesized using β-benzoylacrylic acid as starting material by esterification and elimination reaction.The by-product produced in the process of esterification could be converted into the desired product efficiently by elimination reaction under vacuum in the presence of sulfuric acid.The optimum conditions of esterification were as follows∶n(β-benzoylacrylic acid)∶n(ethanol)∶n(sulfuric acid)=1∶14∶0.28,refluxing reaction time 3 h.The optimum conditions of elimination reaction were as follows:reaction pressure 2.66 kPa,reaction time 5 h,reaction temperature 40 ℃.The yield of ethyl β-benzoylacrylate based on β-benzoylacrylic acid was 81.7% and purity was 97.0%.
