Abstract:
     A synthesis method for aromatic alkylated catalyst relats to aromatic alkylation field. Said catalyst may catalyze the alkylation of aromatic and isomerization of dialkyl aromatic. Metallic aluminum powder is used as raw material which is reacted with anhydrous hydrogen chloride in aromatic medium. A definite quantity of olefin is added at the same time which may achieves a higher activited complex compound catalyst. The alkylated reaction among aromatic and olefin may be carried on quantatively, and also may catalyze the isomerization for isopropyl toluene isomer, during the quantities of said catalyst being used above 0.5%. The isomer mixture of meta more than 60%, para more than 30% and ortho less than 4% are obtained.
