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).
Claims22
A method of alkylating an aromatic compound with an alkene, comprising contacting the aromatic compound and the alkene together in the presence of an oxide of zirconium which has been activated with an acidic tungsten moiety, under effective alkylation conditions.
