Preparation of solid superacid catalysts by chemical modification of oxides. II.

Abstract
Acid properties of the oxides Al2O3, SiO2, TiO2, SnO2, Sb2O3, ZrO2 and ZrSiO4 were modified by the action of Lewis acids. The acids ( AlCl3, TiCl4, PCl5, SbF5 and P2O5) were deposited on the oxides by sublimation at 150, 250 and 350°C. The strength and number of acid centres of the prepared catalysts and their catalytic activity in hydrocarbon reactions were determined.
