Abstract: This paper reports the synthesis of butyl chloro acetate using tin (Ⅳ) chloride pentahydrate (SnCl 4·5H 2O)as catalyst.The optimum reaction conditions were the molar ratio of butyl alcohol,choroacetate and catalyst,2∶1∶0.005,and reaction time of 2.5 h.Under the optimum conditions,the esterification per centage of 97.5% and the yield of 93.6% were given.
