The acidity evaluations using butylamine titration have been carried out to correlate the surface acidic properties of TiO2-SiO2-Al2O3 catalysts with their alkylating activity.The acid amount of TiO2-SiO2-Al2O3 of silica to alumina molar ratio 16.4 and titania content 10.4percent (by weight) is nearly double that of SiO2-Al2O3 of the same silica to alumina molar ratio.The acid strength of TiO2-SiO2-Al2O3 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.
