The acidity evaluations using butylamine titration have been carried out to correlate the surface acidic properties of TiO<SUB>2</SUB>–SiO<SUB>2</SUB>–Al<SUB>2</SUB>O<SUB>3</SUB> catalysts with their alkylating activity. The acid amount of TiO<SUB>2</SUB>–SiO<SUB>2</SUB>–Al<SUB>2</SUB>O<SUB>3</SUB> of silica to alumina molar ratio 16.4 and titania content 10.4% (by weight) is nearly double that of SiO<SUB>2</SUB>–Al<SUB>2</SUB>O<SUB>3</SUB> of the same silica to alumina molar ratio. The acid strength of TiO<SUB>2</SUB>–SiO<SUB>2</SUB>–Al<SUB>2</SUB>O<SUB>3</SUB> coprecipitated from a solution of pH 2 and the acid amount of the same ternary oxide coprecipitated from solutions of higher pH(>6) are low.
