  • US Patent:
    42516641, Feb 17, 1981
  • Filed:
    May 24, 1978
  • Appl. No.:
    5/909154
  • Inventors:
    Ernest B. Spitzner - Minneapolis MN
  • Assignee:
    Henkel Corporation - Minneapolis MN
  • International Classification:
    C07D28512
    C22B 1512
    C22B 1920
    C22B 2300
  • US Classification:
    548138
  • 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.

    Ernest Spitzner - Minneapolis MN
  • Assignee:
    Henkel Corporation - Minneapolis MN
  • International Classification:
    C07D21377
  • US Classification:
    546306
  • Abstract:
    Certain sulfonylhydrazines, metal complexes thereof and solutions of said compounds in essentially water-immiscible, liquid hydrocarbon solvents are disclosed. The sulfonylhydrazines have the general structural formula: R--SO. sub. 2 NHNH--R. sub. 1 wherein R and R. sub. 1 are as defined in the specification and claims hereof. Particular metal values are recovered from their aqueous solutions by using sulfonylhydrazines dissolved in essentially water-immiscible, liquid hydrocarbon solvents. The extraction process involves contacting the metal value containing aqueous solution with the solution of the sulfonylhydrazines in essentially water-immiscible, liquid hydrocarbon solvent and stripping the metal from the loaded organic phase.

  • US Classification:
    2604381
  • 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.
