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:, ω(catalyst) was %; cyclohexa
