氯化铜催化合成乳酸正丁酯

Synthesis of n-Butyl Lactate Catalyzed by CuCl_2·2H_2O

以氯化铜为催化剂 ,合成乳酸正丁酯。考察了醇酸比、催化剂用量、反应时间及带水剂对产率的影响 ,确定了该反应的最佳条件。结果表明 ,最佳反应条件下 ,产率可达 87.6 %。

The n-butyl lactate was synthesized used CuCl_2·2H_2O as catalyst. The effect of molar ratio of n-butanol to lactate, the amount of catalyst, reaction time and water-carrying agent on the yield of ester was studied. The optimum condition of reaction was determined. The result showed that the yield of n-butyl lactate was up to 87.6%.
