采用溶胶 凝胶方法制备了负载磷钨酸催化剂 ,以乙酸异戊酯的合成反应为模型反应 ,详细研究了这种催化剂对酯化反应的催化活性和使用寿命 ,确定了采用负载磷钨酸催化剂催化合成乙酸异戊酯反应的较佳合成条件。
The phosphotungstic acid catalyst was prepared by sol-gel method. The synthesis reaction of isopentyl acetate was taken as the model reaction. The catalytic activity and service life of the catalyst for esterification were studied in detail. The optimum conditions for the synthesis of isoamyl acetate catalyzed.
