  • Electrolytic process for preparing metal sulfonates
    Patent number: 6790338
    Abstract: A method for preparing metal salts of organic sulfonic acids such as tin alkane sulfonates by electrolysis is described. The method comprises: (A) providing a membraneless electrolytic cell having an upper section and a lower section, and comprising: (i) a metal anode positioned in the lower section of the electrolytic cell, and (ii) a cathode positioned in the upper section of the electrolytic cell, (B) charging to the cell, an aqueous solution of an organic sulfonic acid, (C) passing a current through the cell whereby the metal of the anode dissolves in the sulfonic acid and forms the desired metal sulfonate, (D) accumulating the metal sulfonate in a lower portion of the lower section of the cell, and (E) recovering an aqueous solution of the desired metal sulfonate from the lower portion of the lower section of the cell.

  • Process for recovering the carbide metal from metal carbide scrap
    Patent number: 6395241
    Abstract: The process of the present invention relates to a process for recovering the carbide metal from metal carbide scrap wherein the metal is tungsten, titanium, vanadium, chromium or molybdenum, and this process comprises (A) providing a mixture comprising the metal carbide scrap and at least a stoichiometric amount, based on the amount of carbide metal present in the scrap, of an alkali metal hydroxide, (B) heating the mixture in the presence of oxygen at an elevated temperature and pressure for a period of time sufficient to form a water soluble alkali metal salt of the carbide metal, and (C) recovering the water soluble alkali metal salt.
