  • Compounds containing perfluoroalkyl-cyano-alkoxy-borate anions or perfluoroalkyl-cyano-alkoxy-fluoro-borate anions
    Patent number: 8901340
    Abstract: The present invention relates to compounds containing perfluoroalkyl-cyano-alkoxy-borate anions or perfluoroalkyl-cyano-alkoxy-fluoro-borate anions, ((per)fluoro)phenyl-cyano-alkoxy-borate anions or ((per)fluoro)phenyl-cyano-alkoxy-fluoro-borate anions or phenyl-cyano-alkoxy-borate anions which are monosubstituted or disubstituted with perfluoroalkyl groups having 1 to 4 C atoms or phenyl-cyano-alkoxy-fluoro-borate anions which are monosubstituted or disubstituted with perfluoroalkyl groups having 1 to 4 C atoms, the preparation thereof and the use thereof, in particular as part of electrolyte formulations for dye sensitized solar cells.

  • Process for separating metals
    Patent number: 6911135
    Abstract: A method for separating a metal from a composition including the metal involves forming an electrolytic cell in which the anode comprises a composition including the metal. The electrolyte is an ionic liquid. A sufficient potential difference is applied between the anode and the cathode to cause the metal to transfer from the anode to the cathode deposited thereon.

  • Treatment of molten salt reprocessing wastes
    Patent number: 6468495
    Abstract: A method of removing from a metal salt ionic species contained therein involves contacting the metal salt with an ionic liquid to dissolve the metal salt, the ionic species or both. At least in the case where both the metal salt and the ionic species are dissolved, the resultant ionic liquid composition is treated to separate the ionic species therefrom and subsequently processed to recover the metal salt.
