| Abstract: | This paper describes a new method of synthesis of chloroacetic ester from chloroacetic acid and fatty alcohol, and the experiment is carried out by the action of catalytic agent, the dehydration of calcium oxide and the direct esterification using Soxhelt extraction apparatus. In this method, only 2～3 h of the reaction time if the esterification are needed, and the yield is up to 93%～98%. The effects of varrious factors on the reaction yields are examined and the best reaction conditions are found out. |
