DEHYDRATION OF ISOPROPANOL OVER ORGANICALLY PILLARED ZIRCONIUM PHOSPHATES.
Samples of alpha -zirconium phosphates and organically pillared zirconium phosphates were characterized by determining BET surface area, surface acidity, adsorption capacity for nitrogen and isopropanol, and activity in isopropanol decomposition. The BET surface areas of pillared zirconium phosphates were found to increase with the increased sizes of organic groups in the interlayers. The total number of surface acidic sites of alpha -zirconium phosphates were found to be more than any one of the pillared catalysts, although those of the latter were the same order of magnitude. It was concluded in this study that the reaction of isopropanol could only take place on the outer surface of the crystals of these catalysts.
