Direct Black 80 Chemical Properties,Usage,Production

Chemical Properties

dark blue to black powder

Preparation

N-(4-aminophenyl)acetamide diazo, The reduction of the conditions with?6-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, acylation, three amino nitrogen, which then double first and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid, again in three alkaline conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid? coupling.

General Description

Bluish-black to black powder. Odorless.

Air & Water Reactions

Water soluble. Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water.

Reactivity Profile

Direct Black 80 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. Direct Black 80 is incompatible with oxidizing and reducing agents.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition Direct Black 80 emits toxic fumes of nitrogen oxides.

Fire Hazard

Flash point data for Direct Black 80 are not available; however, Direct Black 80 is probably combustible. Dust may form explosive mixtures with air.

Properties and Applications

black. Blue-black uniform powder. Soluble in water for a blue-black, insoluble in organic solvents. The strong sulfuric acid for blue, purple precipitation after diluted; In nitric acid solution for yellow light red; Partly dissolved in strong hydrochloric acid for purple. The dye solution to join 10% sodium hydroxide solution for red light blue. Used for cellulose fiber dyeing, also can be used for paper and leather color.
