| abstract |
The invention concerns a method for selective hydrogenation of diolefin compounds into monoolefin compounds using a catalyst composition comprising at least one salt of transition metal of groups IB, IIB, VB, VIB, VIIB and VIII of the periodic table, at least one ligand and at least one organometallic reducing agent, optionally in the presence of a non-aqueous ionic liquid selected from the group consisting of liquid salts of general formula Q<+>A<-> (wherein Q<+> represents a quaternary ammonium and/or a quaternary phosphonium and A<-> represents any anion capable of forming a liquid salt below 90 DEG C). |
