  • Patent number: 8742145
    Abstract: The present invention provides a method for producing an epoxy compound, comprising oxidizing a carbon-carbon double bond of an organic compound by hydrogen peroxide in the presence of a neutral inorganic salt and a mixed catalyst of a tungsten compound (a), at least one phosphorus compound selected from the group consisting of phosphoric acids, phosphonic acids, and salts thereof (b) and a surfactant (c), and an epoxidizing method comprising oxidizing a carbon-carbon double bond by hydrogen peroxide in the presence of the catalyst and the neutral inorganic salt.
    Type: Grant

  • Patent number: 8466303
    Abstract: A novel process for producing a polyfunctional epoxy monomer is provided that facilitates separation of an aqueous layer catalyst from a reaction solution and has satisfactory hydrogen peroxide efficiency by reacting an aqueous hydrogen peroxide solution with a polyolefin without using an organic solvent and under mild conditions. The process in the present invention is a process for producing a corresponding epoxy compound by reacting an organic compound having a carbon-carbon double bond with hydrogen peroxide present in an aqueous hydrogen peroxide solution to epoxidate the double bond, wherein a tungsten compound and tertiary amine are used as reaction catalysts.

  • Patent number: 8309762
    Abstract: It is an object of this invention to provide a method for efficiently synthesizing monocarboxylic acid, dicarboxylic acid, and tricarboxylic acid with the use of unsaturated triacyl glycerol as a starting material and hydrogen peroxide as an oxidant. Such method comprises allowing unsaturated triacyl glycerol to react with hydrogen peroxide in the presence of a quaternary ammonium polybasic acid hydrogen salt and at least one member selected from the group consisting of tungstic acid, heterotungstic acid, and salts thereof.
