| Abstract: | n-Butyl lactate was synthesised by lactic acid and n-butyil alcohol in the presence of HClO4-SiO2.The influential factors were investigated.Experimental results indicated that the optimum condition was as follows：molar ratio of n-butyl alclhol to lactic acid was 3∶ 1,the mass of catalyst was 2.0%,reflux reaction time was 2 h,the yield of n-butyl lacate reached 93.8%.This catalyst had many advantages,such as easy to be made,feasible to be used repeatedly and so on. |
