    Type: Grant
    Filed: February 19, 1980
    Date of Patent: February 24, 1981
    Assignee: Henkel Corporation
    Inventors: Leroy O. Krbechek, Ernest B. Spitzner, James P. Clark
  • Sulfonamidothiadiazoles, metal complexes thereof, and solutions containing such compounds for use in extraction of metal values
    Patent number: 4251664
    Abstract: Certain sulfonamidothiadiazoles, metal complexes thereof and solutions of said compounds in essentially water-immiscible, liquid hydrocarbon solvents are disclosed. The sulfonamidothiadiazoles have the general structural formula: ##STR1## wherein R and A are as defined in the specification and claims hereof. Particular metal values are recovered from their aqueous solutions by using sulfonamidothiadiazoles dissolved in essentially water-immiscible, liquid hydrocarbon solvents. The extraction process involves contacting the metal value containing aqueous solution with the solution of the sulfonamidothiadiazole in essentially water-immiscible, liquid hydrocarbon solvent and stripping the metal from the loaded organic phase.
    Type: Grant
    Filed: May 24, 1978

    Assignee: Henkel Corporation
    Inventor: Ernest B. Spitzner
  • Sulfonylthiosemicarbazides, metal complexes thereof, and solutions containing such compounds for use in extraction of metal values
    Patent number: 4237062
    Abstract: Certain sulfonylthiosemicarbazides, metal complexes thereof and solutions of said compounds in essentially water-immiscible, liquid hydrocarbon solvents are disclosed. The sulfonylthiosemicarbazides have the general structural formula: ##STR1## wherein R and R.sup.1 are as defined in the specification and claims hereof. Particular metal values are recovered from their aqueous solutions by using sulfonylthiosemicarbazides dissolved in essentially water-immiscible, liquid hydrocarbon solvents. The extraction process involves contacting the metal value containing aqueous solution with the solution of the sulfonylthiosemicarbazide in essentially water-immiscible, liquid hydrocarbon solvent and stripping the metal from the loaded organic phase.
