A catalyst is formed from a phosphorus-containing ZSM-5-type zeolite. The ZSM-5-type zeolite has a silica/alumina molar ratio of at least 200. The phosphorus-containing ZSM-5-type zeolite also has a phosphorus content of at least 8% by weight of zeolite and has multiple phosphorus species exhibited by at least two 31P MAS NMR peaks with maxima at from about 0 to about -50 ppm. The catalyst may be used in aromatic alkylation by contacting the catalyst with a feed of an aromatic hydrocarbon and an alkylating agent under reaction conditions suitable for aromatic alkylation.
