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.
