  • 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.

  • Patent number: 5332709
    Abstract: A stabilized aqueous solution for use in preparing catalysts is described which comprises water, at least one Group VIB element, at least one Group VIII element, an inorganic phosphorus-containing acid, and an amount of a reducing agent effective to dissolve the Group VIB and Group VIII elements and stabilize the solution. Examples of useful reducing agents include hydrazine compounds and hydroxylamine compounds.

  • Patent number: 5210245
    Abstract: Gold carboxylates and a process for preparing gold salts of organic carboxylic acids are described. The gold carboxylates are represented by the formula ##STR1## in which R represents hydrogen or an organic group of valence y and x, y and z each represent a positive integer such that x=y.multidot.z/3. The process comprises reacting an alkali or alkaline earth metal salt of an organic carboxylic acid with a gold salt in an organic liquid which at least partially dissolves the alkali and/or alkaline earth metal salt, the gold salt, and the desired gold carboxylate product, but is not a solvent for the salt formed between the alkali or alkaline earth metal and the anion of the gold salt.

  • Patent number: 5149854
    Abstract: The present invention relates to a process for preparing platinum group metal and rhenium salts of organic carboxylic acids and products obtained using the disclosed process. The process comprises reacting an alkali or alkaline earth metal salt of an organic carboxylic acid with a platinum group metal or rhenium salt in an organic liquid which at least partially dissolves the alkali and/or alkaline earth metal salt, the platinum group metal or rhenium salt, and the desired platinum group metal or rhenium carboxylate product, but is not a solvent for the salt formed between the alkali or alkaline earth metal and the anion of the platinum group metal or rhenium salt.
