| Hazard Information | Back Directory | [Uses]
Mordant Brown 33 is mainly used for dyeing wool tops, yarns, and various woolen fabrics, especially carpets. It can also be used for dyeing silk, nylon, fur, leather, etc., and for printing on wool or silk fabrics pretreated with chromium acetate. Dyeing should preferably be done using a post-mortem dyeing method. This product is sensitive to acids and alkalis; excessive acid content or aldehydes in the auxiliaries will cause the color to turn red. Carbonization treatment is not recommended for dyed materials. | [Preparation]
2-Amino-4-nitrophenol diazotization, and?2,4-Diaminobenzenesulfonic acid coupling. | [Flammability and Explosibility]
Nonflammable | [Properties and Applications]
yellow brown. Yellow brown powder. In the water solubility for 100 g/l (80 ℃), soluble in water and ethanol for yellow brown, and soluble in Cellosolve, slightly soluble in Acetone, insoluble in other organic solvent. Dye in concentrated sulfuric acid to red to red light brown, dilution have orange precipitation; In concentrated nitric acid for red solution, and then to yellow brown. Its aqueous solution for yellow light brown, add concentrated hydrochloric acid to brown light orange, Add sodium hydroxide solution to orange. Dyeing encounter copper ion color darker, iron ion is yellow. Mainly used for wool fabric dyeing, especially suitable for carpet, wool and wool top dyeing, also used for silk, nylon and leather dyeing. Also can be used for wool and a variety of fibre blended with bath dyeing. Can also be used for acetic acid chromium pretreatment of wool and silk fabric direct printing.
