  • Patent number: 8846973
    Abstract: A production method of a hydrogenated product of aromatic polycarboxylic acid by the hydrogenation of aromatic ring of the aromatic polycarboxylic acid in the presence of a catalyst composed of rhodium in combination with palladium and/or platinum supported on a carbon support. By using the catalyst, the hydrogenated product of aromatic polycarboxylic acid is produced industrially advantageously in high purity and high yield. By activating the catalyst composed of rhodium in combination with palladium and/or platinum supported on the carbon support after the hydrogenation, the conversion to the hydrogenated product of aromatic polycarboxylic acid is maintained at nearly 100% even after repeatedly using the catalyst many times. Also, a hydrogenated product of aromatic polycarboxylic acid substantially free from the starting aromatic polycarboxylic acid is obtained.

The present invention is also directed to a method of preparing the polymeric pigment dispersant. In this method, the dipentaerythritol and the hexahydrophthalic anhydride are polymerized to form an intermediate compound. Next, an epoxy group of the glycidylneodecanoate reacts with the intermediate compound, and then the dimethylethanolamine salts the intermediate compound. Finally, the polyphosphoric acid is added to form the completed polymeric pigment dispersant. The polymeric pigment dispersant has improved stability in the pigment dispersion and is utilized for efficient wetting and grinding of the pigment in the pigment dispersion.

  • Publication number: 20030149150
    Abstract: Compounds and compositions comprising specific metal salts of hexahydrophthalic acid (HHPA) in order to provide highly desirable properties within thermoplastic articles are provided. The inventive HHPA derivatives are useful as nucleating and/or clarifying agents for such thermoplastics, are practical and easy to handle. Such compounds provide excellent crystallization temperatures, stiffness, and acid scavenger compatibility within target polyolefins. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Thermoplastic additive compositions and methods of producing polymers with such compounds are also contemplated within this invention.

  • Patent number: 6541662
    Abstract: A process for producing a hydrogenation product of aromatic carboxylic acid which comprises continuously producing the hydrogenation product of aromatic carboxylic acid by hydrogenating an aromatic carboxylic acid having a melting point of 250° C. or higher in a solvent in the presence of a solid catalyst, wherein the hydrogenation is conducted in a condition such that substantially the entire amount of the aromatic carboxylic acid of a raw material is dissolved in the solvent by recycling a portion of a reaction liquid taken out of a reactor into the reactor. An aromatic carboxylic acid having a high melting point and hardly soluble in solvents can be hydrogenated at a suitable reaction temperature in accordance with a continuous process without using a great amount of a solvent and the reaction product of the object compound can be produced very efficiently.
