CHLORAZOL BLACK BH Chemical Properties,Uses,Production

Uses

Direct Blue 2 is an organic azo dye and ground water pollutant, removed via enzymic decolorization by laccase.

Preparation

4-(4-Aminophenyl)benzenamine double nitriding, in alkaline conditions respectively with the 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling.

General Description

Dark blue-black powder.

Air & Water Reactions

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

Reactivity Profile

CHLORAZOL BLACK BH 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.

Fire Hazard

Flash point data for CHLORAZOL BLACK BH are not available, but CHLORAZOL BLACK BH is probably combustible.

Properties and Applications

dark blue. Blue gray powder. Soluble in water for deep purple to black, solubility 35 g/L (85 ℃), slightly soluble in ethanol and soluble fiber element. The strong sulfuric acid in blue, diluted red for purple; In nitric acid for brown in the light purple. The dye solution to join strong hydrochloric acid for red light purple; Add thick sodium hydroxide solution for purplish red color. For cellulose fiber dyeing, the dye absorption rate as well, in 60 ~ 80 ℃ temperature when the biggest affinity. Discharge good, after staining with chromogenic diazotization colorimetric method: use Naphthalen-2-ol show color get navy, between 2 amine with benzene show color get black. Mainly used for cotton, viscose, silk, leather and pulp color.
