| Abstract: | In the presence of aminosulfonic acid catalyst,lactic acid reacted with n butyl alcohol to form n butyl lactate.The optimum conditions were as follows:molar ratio of lactic acid to n butyl alcohol was 1∶4 5,reaction time of reflux was 120-150 min,mass of catalyst was 1 g(based on 0.085 mol lactic acid).The yield of n butyl lactate reched 84%.The catalyst had many advantages,such as easy to be recovered,feasible to be used repeatedly,and less pollution to the environment. |
