  • Patent number: 7196227
    Abstract: Disclosed is a process for the recovery of phosphorus and/or iodine containing catalyst components, present as an organophosphorus compound such as trihydrocarbylphosphine compounds and tetrahydrocarbylphosphonium compounds, from a solution of at least one such organophosphorus compound in an organic solvent by the steps comprising (1) converting the organophosphorus compound to an iodide complex of a organophosphonium compound which is insoluble in the organic solvent; and (2) separating the insoluble iodide complex of the organophosphonium compound from the solution. The process also results in the recovery of iodine values present in the solution.

  • Publication number: 20040222401
    Abstract: Based on the discovery that the melting point and solubility of onium salts are affected by the asymmetry of the substitution on cation, and that the branched substituents effectively shield onium cations from electrochemical reduction, new onium salts are synthesized and high performance electrolytes based on these salts for electrochemical capacitor are provided. The composition of the new electrolyte comprises an onium salt or mixture of such onium salts dissolved in aprotic, non-aqueous solvents or mixture of such solvents. The electrolyte is able to perform at high rate of charge/discharge, at low ambient temperatures, and within wide operating voltage, due to the high solubility, low melting temperature, and the improved reduction stability of the new onium cations, respectively.
