| Direct Fast Brown M is a direct dye used with textiles. It is a water pollutant, removed from the environment via adsorption by magnetic nano cobalt ferrite doped Capra aegagrus hircus dung activated carbon composite. | |||||||||||||||||||||||||||||
| Preparation | 4-(4-Aminophenyl)benzenamine double nitriding, first coupled with 2-Hydroxybenzoic acid, and then in alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid? coupling. | ||||||||||||||||||||||||||||
| Reddish-brown solid or dark brown powder. | |||||||||||||||||||||||||||||
| Air & Water Reactions | Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water. | ||||||||||||||||||||||||||||
| DIRECT FAST BROWN M is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. | |||||||||||||||||||||||||||||
| Hazard | Low toxicity by ingestion. | ||||||||||||||||||||||||||||
| Flash point data for DIRECT FAST BROWN M are not available, however, DIRECT FAST BROWN M is probably combustible. | |||||||||||||||||||||||||||||
| Properties and Applications | red light brown. Brown powder. Soluble in water solution is a deep red light brown, soluble in ethanol is palm red light, soluble in soluble fiber element for red light brown, slightly soluble in acetone, insoluble in other organic solvents. The strong sulfuric acid for purple, diluted red light brown, precipitation; In nitric acid for orange brown. The dye solution to join strong hydrochloric acid for dark brown; Add thick sodium hydroxide solution for orange brown. Cellulose fiber of dyeing, dye devoured rate is good, the temperature of 60 to 80 ℃ in the biggest affinity, discharge of dyeing with copper sulfate after treatment, it can improve the color fastness. Mainly used for cotton, such as glue of cellulose fiber dyeing and printing directly, can also be used for the pulp, leather dyeing and manufacturing color pigment sediment.
