<P>PROBLEM TO BE SOLVED: To provide a catalytic composition for the dimerization of olefins which has high and stable activity and a high degree of selectivity. <P>SOLUTION: The catalytic composition for the dimerization of olefins comprises at least one nickel compound mixed or complexed with at least one tertiary phosphine, dissolved at least partly in a non-aqueous medium of ionic type resulting from the contacting of at least one aluminum halide with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, and with at least one aromatic hydrocarbon. <P>COPYRIGHT: (C)2008,JPO&INPIT |
