  • Publication number: 20180105481
    Abstract: A novel method for the catalytic selective decarboxylation of a starting material to produce an organic acid is disclosed. According to at least one embodiment, the method may include placing a reaction mixture into a reaction vessel, the reaction mixture including a solvent, a starting material, and a catalyst, subjecting the reaction mixture to a predetermined pressure and temperature, and allowing the reaction to continue for 1-3 hours. The starting material may be at least one of a dicarboxylic acid, a tricarboxylic acid, and an anhydride of a dicarboxylic or tricarboxylic acid. As an exemplary embodiment, itaconic acid may be a starting material and the organic acid may be methacrylic acid. The predetermined temperature may be 250° C. or less, and the reaction pressure may be less than 425 psi. Further, a polymerization inhibitor may be used.

  • Patent number: 9540264
    Abstract: We have now discovered a novel process for the removal or extraction of metal species from a variety of solid, liquid or gas phase materials. Metal species may be removed by contacting the material suspected of containing one or more metals with a thiolated fatty acid or ester thereof for a period of time and under conditions effective far the sequestration of the metal species by the thiolated fatty acid or ester thereof. The thiolated fatty acid or ester thereof comprising sequestered metal species may then be separated and recovered from the treated material. Moreover, following the treatment of aqueous liquids or mixtures, or suspensions or dispersions of solids in aqueous liquids, the resultant thiolated fatty acid or ester thereof comprising the sequestered metal species is insoluble in water and forms a separate layer from the aqueous liquid phase, which layer may be readily removed.
