- Preparing methods of p-aminophenyl-beta-hydroxyethylsulfonyl and p-minophenyl-beta-hydroxyethylsulfonyl sulphonate
-
The invention relates to preparing methods of p-aminophenyl-beta-hydroxyethylsulfonyl and p-minophenyl-beta-hydroxyethylsulfonyl sulphonate. The preparing methods both comprise the steps that p-aminophenyl-beta-hydroxyethylsulfonyl and hydrogen are used as raw materials, modified framework nickel is used as a hydrogen-adding catalyst, a catalytic hydrogenation reaction is conducted in a solvent toobtain reduction liquid, and modified framework nickel and the solvent in the reduction liquid are separated and removed to obtain p-minophenyl-beta-hydroxyethylsulfonyl sulphonate; according to modified framework nickel, nickel is used as a framework, and modified framework nickel is prepared from, by mass, 75-95 parts of Ni, 3-15 parts of Al and 2-10 parts of metal adjuvant; the metal adjuvantcomprises the combination of any one or at least two of Mo, Cu and Cr. The yield can reach 94% or above; preparation of p-minophenyl-beta-hydroxyethylsulfonyl sulphonate is a continuous production technology, the technology is simplified, the production efficiency is high, the quality is stable, the production cost is low, and the economic benefit and social benefit are obvious.

- Dye compounds and resin composition for color filter comprising the same
-
The present invention relates to a pyridone azo dye compound for a color filter resin composition having excellent solubility and heat resistance, which is represented by the following chemical formula 1 and contains an acrylic group or a meta-acrylic group. The pyridone azo dye compound according to the present invention has excellent solubility and heat resistance with respect to an organic solvent, thereby having higher solubility as a coloring agent of the color filter resin composition than a pigment; and maximizing coloring performance and realizing high color reproducibility by reducing an amount of an additive added for pigment dispersion stability.

- Process for producing aminophenyl-β-hydroxyethylsulfone
-
A process for producing aminophenyl-β-hydroxyethylsulfone of the formula (I), STR1 which comprises the following steps: (1) condensing nitrohalobenzene with mercaptoethanol in the presence of an alkali hydroxide and at least one reaction medium selected from N-alkyl-substituted amides and sulfoxides to produce mononitrophenyl-β-hydroxyethylsulfide of the formula (II): STR2 (2) oxidizing the mononitrophenyl-β-hydroxyethylsulfide (II) to produce mononitrophenyl-β-hydroxyethylsulfone of the formula (III): STR3 and (3) reducing the mononitrophenyl-β-hydroxyethylsulfone to produce the aminophenyl-β-hydroxyethylsulfone of the formula (I). This compound is useful as an intermediate for aminophenyl-β-sulfatoethylsulfone represented by the following formula: STR4 which is an important intermediate for vinyl sulfone type reactive dyes largely used for dyeing cellulose fiber materials.
