Catalytic composition, useful for the (co)dimerization/oligomerization of an olefin, is in the form of a solution comprising an zero-valent nickel complex, an acid and an ionic liquid

摘要

A catalytic composition is in the form of a solution comprising at least one zero-valent nickel complex, at least one acid and at least one ionic liquid that is liquid below 150 degreesC. A catalytic composition (I) is in the form of a solution comprising: (A) at least one zero-valent nickel complex; (B) at least one acid of formula H+X- (1); and (C) at least one ionic liquid of formula Q+A- (2) that is liquid below 150 degreesC. X-, A- = anion; Q+ = quaternary ammonium, phosphonium and/or sulfonium An Independent claim is included for a process for the dimerization, co-dimerization or oligomerization of at least one olefin, comprising ethylene, propylene, n-butene and/or n-pentene optionally diluted by an alkane or fractions from catalytic cracking or steam cracking, by means of the catalyst composition (I).
