Abstract:The Friedel–Crafts alkylation reactions of Methylation of toluene using methanol, ethanol, isopropylation and 2-propanol in liquid-phase over environmentally friendly zeolite catalysts had been investigated in a down reactor under atmospheric conditions over a series of surface modified and unmodified ZSM loaded with H3PO4, differing in the external surface treatment of the zeolites. The feed molar ratios of toluene/methanol and toluene/2-propanol were varied over a wide range (8–0.125), and the optimum feed ratio of toluene/alcohol was less than 0.5 in both cases.
