Abstract:

 

A mesoporous MCM-41 molecular sieve material with a molar ratio of  SiO2/Al2O3 = 70 and loaded with H3PO4 was  used as a catalyst for the alkylation of toluene, using various  alcohols, namely methanol, iso-propanol, and  tert-butanol, as alkylating agents.  Para-alkylated  toluene was the predominant product, formation of which was enhanced  by moderate temperature, low amounts of the alkylating agents in the  feed, and high carrier gas flow rate.  Time on stream was found to  exert a profound effect on the selectivity and conversion to the  different products.
