Abstract

A product consisting predominantly of branched chain dimers having internal unsaturation and also containing linear dimers is obtained by dimerization of an alpha-olefin feed consisting of one or more alpha-olefins containing three or more carbon atoms per molecule in the presence of a catalyst comprising the reaction product of a reducible salt of a Group VIII metal (Mendeleef table) and a reducing agent comprising a Grignard reagent, a metal alkyl or another organo-metallic compound, the molar ratio of reducible salt to reducing agent being in the range 2:1 to 1:10, at - 40 to +200 DEG C. under a pressure such that the reactants are maintained in the liquid or partially condensed phase, i.e. preferably 200-2000 p.s.i.g. The catalyst may comprise cobalt or nickel chloride and aluminium diethyl monochloride or aluminium triethyl. Specified feedstocks are propylene or butene-1. A saturated hydrocarbon or halogenated hydrocarbon diluent may be present. In the Example, propylene in diluent heptane dimerized to a product containing 49.5% 4-methylpentene-2, 12.5% 2-methyl pentene-2 and 21.0% hexene-2.
