摘　　要：This paper described a new method for preparation of ethyl lactate from ammonium lactate directly by means of reactive distillation in the presence of anhydrous aluminium chloride as catalyst and benzene as dehydrating agent.The result showed this method had the advantages of high pure,easy operation,and no pollution.The yield of ethyl lactate reached up to 28.14%,which was 50% higher 50% than that in ordinary reactive device.This paper described a new method for preparation of ethyl lactate from ammonium lactate directly by means of reactive distillation in the presence of anhydrous aluminium chloride as catalyst and benzene as dehydrating agent.
