    Abstract: The present invention provides a macromolecular dispersant and a synthesis method thereof, and the dispersant is synthesized by reacting polyisobutylene-g-succinic anhydride with amine compounds. In addition, the present invention also provides an oil-soluble dispersant composition with nano particle pigments and the manufacturing method thereof. The oil-soluble dispersant composition is manufactured by milling a macromolecular dispersant with a pigment and a grinding media. The oil-soluble dispersant composition is adequate for various pigments, shows the excellent immiscibility of oil/water interface, and owns the low viscosity of ?4 cps and the optical density of ink ?1.1. Therefore, the oil-soluble dispersant of the present invention for the nano particle pigment can be acted as the material of the electrowetting display.

  • Patent number: 6846952
    Abstract: A process for producing 4-bromo-2-oxyimino butyric acid, predominantly as the (Z)-isomer of formula (I), wherein R is hydrogen; a linear or branched C1-4 alkyl group; a linear or branched C1-4 alkyl group substituted by a carboxylic acid or an aryl group; a substituted or unsubstituted cyclic alkyl group of 3-6 carbon atoms or a substituted or unsubstituted aryl group. The product is produced by reacting bromine with a 2-(oxyimino)-3-oxo butyric acid derivative of formula (II) wherein R is as defined above and R1 is a tert-butyl group in presence of an organic solvent and in presence of a C1-4 alcohol and acetyl bromide at a temperature ranging from about ?15° C. to about +15° C. Bromine is used in a proportion of about 0.90 to about 1.35 moles per mole of compound (II), preferably 0.90 to 1.10 moles. The acetyl bromide is used in molar proportions of 0.9 to 2 moles per mole of compound (II), preferably 0.9 to 1.5 moles.

  • Patent number: 6515179
    Abstract: A 2- or 4-nitrobenzenesulfonamide is allowed to react with an alkali metal alkoxide to remove a nitrobenzenesulfonyl group to thereby obtain an amine corresponding to the amide. Furthermore, a method for producing an amine derivative by allowing the resulting amine without isolation to react with an activated, substituted oxycarbonyl compound or an activated acyl compound is provided. According to this method, a corresponding free amine and its substituted derivative can be produced easily and industrially advantageously from the 2- or 4-nitrobenzenesulfonamide without using a thiol compound.
