  • Intermolecular compounds of amino acids and sulfoxides and method of preparing same
    Patent number: 4302593
    Abstract: An intermolecular compound of an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble.A method which comprises reacting an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble.A method for recovering an amino acid containing a sulfonic acid group and a carboxylic acid group from an admixture of the amino acid with other ingredients by adding thereto a sulfoxide in which the amino acid is moderately soluble, with the sulfoxide being added in a sufficient amount to solubilize the amino acid, separating an intermolecular compound of the amino acid with the sulfoxide, and then recovering the amino acid from its intermolecular compound.
    Type: Grant

  • Oxidation of thiols to disulfides
    Patent number: 3954800
    Abstract: A process for oxidizing alkyl thiols, cycloaliphatic thiols and aralkyl thiols or mixtures thereof to disulfides. The thiol reactant is oxidized by a sulfoxide reactant in the presence of a halogen-hydrogen halide catalyst. The catalysts for the reaction are iodine, hydrogen iodide, bromine, hydrogen bromide, chlorine, hydrogen chloride and mixtures thereof.
    Type: Grant

    Date of Patent: May 4, 1976
    Inventor: Orville G. Lowe
  • Oxidation of thiols and disulfides to sulfonic acids
    Patent number: 3948922
    Abstract: A process for formation of a sulfonic acid through oxidation of a thiol or disulfide. The process is carried out in the presence of a sulfoxide such as dimethyl sulfoxide, a halogen or hydrogen halide catalyst, and an excess quantity of water. The water acts as a moderator for the oxidation reaction to reduce the level of decomposition of the sulfoxide and, thereby, to improve the overall efficiency of the process.An intermolecular compound of an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble.A method which comprises reacting an amino acid containing a sulfonic acid group and a carboxylic acid group with a sulfoxide in which the amino acid is at least moderately soluble.
