Research on Synthesis Technology of Lactide by Lactic Acid

Qingning Wang

Abstract

Intermediate product lactide was synthesized from lactic acid.The effects of reaction temperature,time,and catalyst on the synthesis were discussed by means of orthogonal experimentation,and the optimum condition was determined:the mass ratio of SnCl2·2H2O to lactic acid was 0.25,p-toluenesulfonic acid to lactic acid was 0.75,reacted at 150 ℃ for 4 h.Lactide yield could reach to 43.3% when 30ml n-octanol was added in the late of the reaction.
