Abstract

1,228,116. Alkylating aromatics. INTERNATIONAL LEAD ZINC RESEARCH ORGANIZATION Inc. 5 Dec., 1969 [6 Dec., 1968; 13 Nov., 1969], No. 59533/69. Heading C5E. Aromatics are alkylated by means of a C 3 or higher alkene and/or a C 2-30 alkyl chloride, bromide or iodide in the presence of an unsupported catalyst comprising (A) TiCl 4 or TiBr 4 , and (B) a diorgano zinc compound of formula R 2 Zn where R is a C 1-18 organic group, the molar ratio A : B being at least 2 : 1. A wide variety of reactants and catalysts are specified. In the examples the aromatics are benzene, toluene, m-xylene and p-xylene; the alkylating agents are ethylene, propylene, butene-1, butene-2, isobutene, octene-1, octadecene-1, butadiene, isopropyl chloride and bromide, and tert.-butyl chloride and bromide; and the catalysts are mixtures of TiCl 4 with diethyl zinc or diphenyl zinc, and a mixture of TiBr 4 with diethyl zinc. The products include mono- and poly-alkylates.
