    Abstract: Anthrone is synthesized by hydration of anthraquinone in organic solvent. Hydration is carried out by Pd/C catalyst and 9-15 parts by weight of chlorobenzene is used as organic solvent. Condensation reaction of anthrone prepared above and glycerin is carried out in the presence of sulfuric acid at the temperature of 105-130 degree Celsius, then benzanthrone with high purity is synthesized.

    Abstract: PURPOSE: Provided is a water-insoluble dispersion-reactive dye having an acetoxy ethyl sulfone reactive group, which reduces pollution, dose not contain hazardous amine and metals, can be used in acidic and neutral condition, and is excellent in washing-fastness and properties. CONSTITUTION: The dispersion-reactive dye(formula 2) having the 4-aminophenyl-beta-acetoxy ethyl sulfone reactive group(formula 1) is produced by a process comprising the steps of: diazotizing the 4-aminophenyl-beta-acetoxy ethyl sulfone(formula 1); making a coupling solution by dissolving a coupler in water and concentrated hydrochloric acid; mixing the diazotized 4-aminophenyl-beta-acetoxy ethyl sulfone with the coupling solution at 0-5deg.C; adding a base to keep pH neutral condition and separating the produced dye. In the formula, R, R1, R2, and R3 are identically or differently hydrogen, alkyl, alkoxy, cyanoalkyl, amino acetyl, and amino ester.
