| Abstract: | With the condition of warm - up temperature and pressure reduction, the dehydration capacity of lactic acid reached more than 90% . The lacfide was synthesized by using supersonic strengthening and purified with the mixture of benzene - acetic by this experiment , the synthesis of the supersonic strengthening was the best technological condition for the lactide . The rate of production reached 42% and the purity was 99.52%. With the micro melting point cryoscope and the IR infrared spectrum analysis carries on the attribute to the product lactide. |
