Synthesis of n-butyl acetate catalyzed by La~(3+)-C

The activated carbon carried La 3+ was used as catalyst for the synthesis of n-butyl acetate.It was researched that the temperature of catalyst, acid-alcohol rate,time,quantity and repeated application of catalyzese had influenced upon yield of esterification reaction. The influent actors of reaction were investigated.The results showed that the appropriate should be: weight of catalyst was 0.8g;molar ratio of n-butanol to ethanoic acid was 2:1; reaction time was 2h;the highest yield of n-butyl acetate was about 98.89%.
