ABSTRACT:
A novel non-aqueous catalytic composition comprises at least one quaternary ammonium and/or phosphonium salt in which the anion is selected from the group consisting of tetrafluoroborate, tetrachloroborate, hexafluorophosphate, hexafluoroantimonate, hexafluoroarsenate, trifluorosulphonate, fluorosulphonate, trifluoromethylsulphonate, trifluoroarsenate, dichlorocuprate, trichlorocuprate, tetrachlorocuprate, and trichlorozincate, and at least one complex of a transition metal from groups 8, 9 or 10, i.e., iron, ruthenium, colbalt, rhodium iridium, nickel, palladium and platinum. The catalyst can be used in a process of total or selective hydrogenation of unsaturated compounds such as monoolefins, diolefins, acetylene compounds, aromatic compounds, or polynuclear aromatic compounds. Hydrogenation may be accompanied by isomerisation.
