Abstract

Mixed Metal Phospho-Sulfates were prepared and evaluated for use as acid catalysts via 2-methyl-2-pentene isomerization and o-xylene isomerization. Particular members of this class of materials exhibit greater levels of activity than sulfated zirconia as well as lower rates and magnitudes of deactivation. 31P MAS NMR has been used to examine the role of phosphorous in contributing to the activity and deactivation behavior of these materials, while powder X-ray diffraction, BET surface area, IR, and elemental analysis were used to characterize the bulk catalysts.
