| Abstract: | Ethyl lactate was synthesized by transesterification of D, L-lactide with ethanol utilizing concentrated sulfuric acid as catalyst. The products were analyzed by infrared spectrometry and gas chromatography-mass spectrometry. The optimum conditions of the reaction were confirmed. The results showed that the yield of ethyl lactate reached 78.6% under the optimum conditions; the purity of the products was up to 100%. The synthetic route was simplified due to no water-separation process. |
