• Acidity and catalytic activity of Zr(SO<SUB>4</SUB>)<SUB>2</SUB> and Ti(SO<SUB>4</SUB>)<SUB>2</SUB> calcined at 500–800°C were studied. The products obtained by calcination at 725°C for Zr(SO<SUB>4</SUB>)<SUB>2</SUB> and at 625°C for Ti(SO<SUB>4</SUB>)<SUB>2</SUB> showed the highest activity for the cracking of cumene among samples calcined at other temperatures; the former showed an acid strength of −13.16<<I>H</I><SUB>0</SUB>≤−12.70 and the activity for the reaction of pentane.
