| Abstract: | In this paper,a new kind of rectifier with water separator is used to synthesize ethyl lactate directly under a certain water entraining agent to take place of old methodologies of lactate-esterifying with include two processes:dehydrating and esterifying.The relation of the yield of ethyl lactate with the mole ratios of acid to alcohol,acid to water entraining agent and acid to catalyst is studied under the orthogonal experiments and a optimum condition is determined.Under the optimum condition esterification could be finished in two hours and the yield of ethy1 lactate is up to 96%. |
