Vat Orange 11

Reddish brown powder. Insoluble in water, ethanol, acetone, chloroform, toluene, slightly soluble in o-chlorophenol, pyridine. Reddish brown in concentrated sulfuric acid, produces brownish yellow precipitate after dilution. Dark reddish brown in alkaline insurance powder reducing solution, dark yellow in acidic solution.

Using 1, 5-diaminoanthraquinone and 1-chloroanthraquinone as raw materials, the product is obtained through condensation, ring closure and oxidation. Put 72kg of 1, 5-diaminoanthraquinone (100%), 168kg of 1-chloroanthraquinone (100%), 71.3kg of sodium carbonate (100%), 3.6kg of copper powder into the condensation kettle, and then dehydrate at 225- React at 230°C for 2h, cool and smash, send it to a boiling pot and boil for 1h, filter while hot, wash with water until neutral, and dry to obtain a condensate. Put 50kg of condensate, 150kg of aluminum trichloride (industrial product), 30kg of refined salt into the reaction pot, heat it to 160-170℃ for 1h, put the material in the dilution pot (previously put in cold water) to produce a large amount of hydrogen chloride gas Absorb with water, filter the diluted material, wash and blow dry to obtain a closed loop product. Put all the condensate obtained above, 400kg water, 26kg liquid caustic soda (30%), 1800L sodium hypochlorite solution (available chlorine content>9%) in the oxidation pot, slowly increase the temperature to 90-95℃ for 1h, add water to dilute, and press filter , Wash to neutral, blow dry to obtain dye products.

Mainly used for roll dyeing and dip dyeing of cotton cloth, which can be directly printed on cotton cloth
