摘要

采用膨润土为负载制备插层固载磷钨酸，用XRD和指示剂法表征了插层物的结构和酸强度，研究酯化过程的催化作用，得到具有高活性、高稳定性的插层固载磷钨酸催化剂，为负载杂多酸在工业上的应用提供了良好的实验结果.

Abstract

In this paper

layer-piller supported phosphotungstic acid(PTA) was prepared in bentonite. The constitution and H0 of layer-piller supported phosphotungstic acid are characterized by XRD and indicator test.Catalysis in esterification

and shows a good activity and stability.Test result is useful for industrial application.
