The liquid phase alkylation of benzene with dec-1-ene was catalyzed by 12- tungstophosphoric acid (WP) supported on different solids (ZrO2, SiO2, activated carbon and boehmite-Al2O3). Catalysts prepared with 20wt.% of WP were thermally treated at 300° C and then the acidity was estimated by FT-IR pyridine adsorption spectroscopy. Additionally, the catalysts were characterized by X-ray diffraction, thermal gravimetric ...
