摘　　要：2-Chiorethyl acrylate was synthesized by transesterification of methyl acrylate and 2-chloroethanol.The effects of species and amount of catalyst and inhibitor,material ratio and reaction temperature on reaction yield were investigated.The optimum reaction conditions were determined that the molar ration of p-toluenesulfonic acid,hydroquinone,methyl acrylate to 2-chioroethanol was 0.06:0.05:3:1 and reaction temperature was 100°C,Under these conditions,the conversion was 95%,yield 90%.2 - Chiorethyl acrylate was synthesized by transesterification of methyl acrylate and 2 - chloroethanol. The effects of species and amount of catalyst and inhibitor, material ratio and reaction temperature on reaction yield were investigated. The optimum reaction conditions were determined that the molar ration of p - toluenesulfonic acid, hydroquinone, methyl acrylate to 2 - chioroethanol was 0.06： 0. 05： 3：1 and reaction temperature was 100℃, Under these conditions, the conversion was 95%, yield 90%.
