    摘要: The present invention relates to a method for the preparation of hydrogen peroxide through a continuous process, extracting hydrogen peroxide produced from reduction and oxidation of a working solution and recycling the oxidized working solution back to the reduction process, wherein the composition of the working solution, i.e. the composition of 2-alkylanthraquinone and 2-tetrahydroalkylanthraquinone, is optimized to increase the solubility of the quinones and to improve the reaction rate. The working solution comprises 2-alkylanthraquinone, 2-tetrahydroalkylanthraquinone and an organic solvent, wherein 65-95 mol % of the alkyl group of 2-alkylanthraquinone and 2-tetrahydroalkylanthraquinone is amyl and the remaining 5-35 mol % of the alkyl group is ethyl, and the molar ratio of 2-alkylanthraquinone to 2-tetrahydroalkylanthraquinone is from 4:6 to 1:9.

    摘要: This invention relates to a novel non-aqueous liquid oxygen bleach composition prepared by dispersing solid peroxygen compound in the liquid in which the content of an anhydrous non-polar organic solvent and a non-ionic and anionic surfactant is controlled. The composition is formed in a high viscous paste or a gel-type suspension and can be used as a multi-purpose composition, for example, the bleach and stain remover of clothes and the cleanser of bathroom and kitchen since they have a chemical/physical stability of no loss of available oxygen, an excellent bleaching and cleaning ability due to their alkaline pH range, no change of viscosity or no phase separation during the storage and so on.

    摘要: The present invention relates to a pigment dispersion and a black water-reducing agent, more particularly, to a pigment dispersion comprising a carbon black whose surface is modified with an aminosilane compound and a polycarboxylic acid-based water-reducing agent, and a black water-reducing agent using the same. The present invention is characterized in that the surface-modified carbon black with an aminosilane compound is water-dispersed by using a polycarboxylic acid-based water-reducing agent as a dispersing agent having better performance than a naphthanlene-based water-reducing agent. Therefore, the present invention can display black color of the water-reducing agent and cement at the same time and improve the flowability of cement owing to the presence of carbon black in the form of nanoparticles, which enables to manufacture ultrahigh strength concrete. Further, by using the method in accordance with the present invention, it is also possible to use conventional polycarboxylic acid-based water-reducing agents as a pigment dispersing agent for carbon black.
