Chemische Eigenschaften
reddish-brown powder
Verwenden
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.
synthetische
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.
Allgemeine Beschreibung
Reddish-brown solid or dark brown powder.
Air & Water Reaktionen
Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water.
Reaktivit?t anzeigen
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.
Brandgefahr
Flash point data for DIRECT FAST BROWN M are not available, however, DIRECT FAST BROWN M is probably combustible.
