DIMERIZATION AND CODIMERIZATION OF OLEFIN AND CATALYTIC COMPOSITION FOR OLIGOMERIZATION

摘要

PROBLEM TO BE SOLVED: To provide a catalytic composition used for dimerization dimerization, codimerization and oligomerization of olefins. SOLUTION: This catalytic composition contains at least one nickel compound which is mixed in or forms complexes with at least one ternary phosphine having functional groups or at least one phoshite having functional groups, at least a part of which is dissolved in a non-aqueous medium having ionic characteristics. The non-aqueous medium is obtained by bringing at least one aluminum halide (substance B) into contact with at least one halogenated quaternary ammonium and/or at least one halogenated quaternary phosphonium (substance A).
