Abstract: The present invention provides electrolytes for use in electronic devices at temperature below ?50° C. consisting of a mixture, eutectic or tereutectic of at least two low viscosity aprotic solvents, acetonitrile, and a mixture of conductive salts having a molecular weight up to 240.
Abstract: The present invention provides a process for preparing hexafluorophosphoric acid complexed with about 1 to 3.3 molecules of water which are stable at temperatures below 20° C. and the compositions prepared thereby.
Abstract: A process for the preparation of anhydrous high purity phosphorus pentafluoride in high yield. The process uses an excess of hydrogen fluoride in a reaction with a phosphoric acid to form hexafluorophosphoric acid followed by reaction with a sulfur based acid reactant in a reaction medium containing an excess of hydrogen fluoride.
