ABSTRACT:
An aromatic compound (such as benzene) is alkylated with a alkene (such as propylene) by contacting the two compounds together in the presence of a tungsten on zirconia catalyst. The reaction preferably takes place at elevated temperature and elevated pressure. The process of the invention has very high selectivity and conversion, and produces no or only very low amounts of undesirable oligomers (as measured by bromine number).
