摘要
以焙烧的Fe2 (SO4 ) 3为催化剂 ,实现了乳酸与正丁酸与正丁醇反应合成乳酸正丁酯 最佳合成条件为 :以 0 0 85mol乳酸为准 ,乳酸与丁醇的摩尔比是 1:4 ,催化剂用量为 2g ,反应时间为 150min ,产率达 87 4 % 该催化剂具有制备易 ,可循环使用 。
In the presence of roasted ferric sulfate as catalyst,lactic acid can react with n butyl alcohol to form n butyl lactate The optimum conditions are follows:molar ratio of lactic acid to n butyl alcohol=1∶4 5,reaction temperature time=150min,weight of catalyst=2g.The yield under the optimum conditions was up to 87 4% The catalyst has many advantages,such as being able to manufacture very easy,use repeatedly and less pollution to the environment
