Product Name:Direct Black 22
English Name:Direct Black 22
CAS No.:6473-13-8
Aliases:Direct Black AB, Direct Black M, C.I. Direct Black 22
Molecular Formula:C44H32N13Na3O11S3
Physical Properties:This product appears as a dark grey to black uniform powder. It is readily soluble in water yielding a blue-black to black solution, slightly soluble in ethanol, and insoluble in acetone. It forms a deep blue color in concentrated sulfuric acid, and produces a black precipitate upon dilution. As an anionic direct dye, it is sensitive to hard water and pH changes during dyeing.
Uses:Mainly used for dyeing and printing of cellulosic fibers such as cotton, linen, and viscose, as well as for paper and leather coloring. It can be applied alone or combined with other direct dyes to obtain various shades. Suitable for conventional exhaustion and jig dyeing processes.
Technical Specifications:
Appearance: dark grey to black uniform powder without visible impurities
Moisture content ≤ 5% by mass
Standard-type direct dye with wash fastness rating of 3-4 and light fastness rating of 3
Good water solubility: ≥ 30 g/L at 25°C
pH value of 1% aqueous solution: 6.5-8.5
