| Abstract: | Propyl chloroacetate was synthesized by the esterification of the chloroacetic acid and propanol using cerium sulphate crystal as catalyst.The appropriate reaction conditions at 95~110℃ for 2hs were as follows：The chloroacetic acid was 50mmol;molar ratio of chloroacetic acid to propanol is 1：1.5,ω（catalyst） was 2.7%;cyclohexane was 2.0mL;the yield of propyl chloroacetate was 97.35% under the condition. |
