General Description
Dull green solid or black powder.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Soluble in water.
Reactivity Profile
disodium 4-amino-5-hydroxy-3-[[4'-[(4-hydroxyphenyl)azo][1,1'-biphenyl]-4-yl]azo]-6-(phenylazo)naphthalene-2,7-disulphonate 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 disodium 4-amino-5-hydroxy-3-[[4'-[(4-hydroxyphenyl)azo][1,1'-biphenyl]-4-yl]azo]-6-(phenylazo)naphthalene-2,7-disulphonate are not available; however, disodium 4-amino-5-hydroxy-3-[[4'-[(4-hydroxyphenyl)azo][1,1'-biphenyl]-4-yl]azo]-6-(phenylazo)naphthalene-2,7-disulphonate is probably combustible.
Properties and Applications
Dark green. Soluble in water for blue light green, soluble in soluble fiber element, and adequate soluble in ethanol and acetone, insoluble in other organic solvents. In the dark for the strong sulfuric acid to blue-black, after dilute black precipitation; In nitric acid partly dissolved, from brown into a red. The dye solution to join strong hydrochloric acid have Gray light purple precipitation; Add thick dark blue purple sodium hydroxide solution precipitation. Suitable for cellulose fiber, silk, polyamide fiber dyeing and printing, also suitable for leather and paper color.
