Abstrakt: Surface properties and catalytic activity for butene isomerization have been investigated for 12-molybdophosphoric acid. The surface area changed reversibly by dehydration and hydration below 300°C, but irreversible destruction was caused at 400°C. The catalytic activities per unit surface area were nearly constant. From these results and infrared spectra of pyridine adsorbed, strong protonic acidity probably of nearly uniform acid strength was concluded.
