Claims21
A method for hydrogenating a compound comprising contacting a reactant comprising an olefin having at least one carbon-fluorine bond with a supported hydrogenation catalyst under reaction conditions effective to form a reaction product comprising a hydrogenated derivative of said olefin, wherein said supported hydrogenation catalyst comprises:
- a. a catalyst comprising an elemental metal selected from Pd, Ru, Pt, Rh, Ir, Fe, Co, Ni, Cu, Ag, Re, Os, Au, and any combinations thereof;
- and
- b. a support comprising at least about 75 wt. % of a metal fluoride selected from the group consisting of CrF3, TiF4, and ZrF4, or a metal oxyfluoride selected from the group consisting of magnesium (II) oxyfluoride, aluminum (III) oxyfluoride, chromium (III) oxyfluoride, titanium (IV) oxyfluoride, and zirconium (IV) oxyfluoride.
A method for hydrogenating a compound comprising contacting a reactant composition comprising 1,1,2,3,3,3-hexafluoropropene with a supported hydrogenation catalyst under reaction conditions effective to form a reaction product comprising 1,1,1,2,3,3-hexafluoropropane, wherein said supported hydrogenation catalyst comprises:
- a. a catalyst comprising an elemental metal selected from Pd, Ru, Pt, Rh, Ir, Fe, Co, Ni, Cu, Ag, Re, Os, Au, and any combinations thereof;
- and
- b. a support comprising at least about 75 wt. % of a metal fluoride selected from the group consisting of CrF3, TiF4, and ZrF4, or a metal oxyfluoride selected from the group consisting of magnesium (II) oxyfluoride, aluminum (III) oxyfluoride, chromium (III) oxyfluoride, titanium (IV) oxyfluoride, and zirconium (IV) oxyfluoride.
A method for hydrogenating a compound comprising contacting a reactant composition comprising 1,2,3,3,3-pentafluoropropene with a supported hydrogenation catalyst under reaction conditions effective to form a reaction product comprising 1,1,1,2,3-pentafluoropropane, wherein said supported hydrogenation catalyst comprises:
- a. a catalyst comprising an elemental metal selected from Pd, Ru, Pt, Rh, Ir, Fe, Co, Ni, Cu, Ag, Re, Os, Au, and any combinations thereof;
- and
- b. a support comprising at least about 75 wt. % of a metal fluoride selected from the group consisting of CrF3, TiF4, and ZrF4, or a metal oxyfluoride selected from the group consisting of magnesium (II) oxyfluoride, aluminum (III) oxyfluoride, chromium (III) oxyfluoride, titanium (IV) oxyfluoride, and zirconium (IV) oxyfluoride.
