摘要: 可用稀土、膨润土单独作醋化催化剂,但活性不高[1-3].本文将稀土用离子交换的方法负载到酸活化膨润土中,寻求一种高活性醋化催化剂的合成方法.

Abstract: The catalytic esterification activity of some bentonite samples treated with different methods were characterized.It was found that the catalytic activity of activited bentonite could be increased greatly by loading with rare earth. However,no evident increase of catalytic activity with the amount of loaded rare earth in bentonite was observed in high rare earth content range.These results showed that the surface acidity and rare earth accounted for the catalytic activity and the former factor played a more important role than the other in the catalytic esterification.

Key words: rare earth, bentonite, catalytic esterification
