Abstract

1,273,252. Alkylating aromatic hydrocarbons. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 7 July, 1969 [9 July, 1968; 28 Oct., 1968], Nos. 27325/69 and 50935/68. Divided out of 1,272,585. Heading C5E. An aromatic hydrocarbon capable of being alkylated with at least 2 alkyl groups per molecule is reacted in a first zone with an alkylating agent in the presence of an acidic crystalline alumino-silicate catalyst, the catalyst being kept at least partially dispersed in a liquid phase by keeping the liquid phase in turbulent motion; and the liquid phase is withdrawn from the first zone and contacted in a second zone with a catalyst comprising non-dispersed aerolic crystalline alumino-silicate, the second zone being maintained free of alkylating agent and alkylation catalyst originating from the first zone. The aromatic starting material may be benzene, alkylbenzenes, naphthalene, alkyl naphthalenes or anthracene. The alkylating agent may be olefins, cyclo-olefins, alkyl halides or alcohols. Polyalkylated aromatics react in the second zone with the starting material to form the mono-alkylated aromatic hydrocarbon. Examples describe the preparation of isopropyl benzene from benzene and propylene using a synthetic faujasite catalyst.
