Estimating the term…
A novel catalytic composition comprises at least one quaternary ammonium and/or phosphonium salt in which the anion is selected from the group formed by tetrafluoroborate, tetrachloroborate, hexafluorophosphate, hexafluoroantimonate, hexafluoroarsenate, trifluorosulphonate, fluorosulphonate, tetrachloroaluminate, dichlorocuprate, and trichlorozincate, and at least one complex of a transition metal from groups 8, 9 and 10, i.e., iron, ruthenium, cobalt, rhodium iridium, nickel, palladium and platinum. Application to total or selective hydrogenation of unsaturated compounds such as monoolefins, diolefins, acetylenic compounds, aromatic compounds, polynuclear aromatic compounds. Hydrogenation may be accompanied by isomerisation.
A process for the hydrogenation of double or triple bonds between carbon atoms in unsaturated hydrocarbon compounds in the presence of a catalytic composition comprising a polar non-aqueous solvent which is ionic in nature and liquid at a temperature below 150.degree. C. mainly containing at least one molten quaternary ammonium and/or phosphonium salt with general formula Q.sup.+ A.sup.-, where Q.sup.+ represents a quaternary ammonium and/or phosphonium cation, and A.sup.- represents an anion, said composition also comprising at least one compound of at least one transition metal from groups 8, 9 or 10 dissolved in said non-aqueous solvent, said non-aqeuous solvent optionally further comprising an organic solvent in an amount less than said molten salt.
