| Chemical Properties | Blue powder, soluble in water, reddish blue solution, insoluble in organic solvents. When concentrated sulfuric acid is bluish green, diluted reddish blue; when concentrated nitric acid is reddish gray solution. Its aqueous solution with concentrated hydrochloric acid, reddish blue precipitate; with concentrated sodium hydroxide solution, purple precipitate. For cellulose fiber dyeing, the dye exhaustion is very good, the temperature in 80-100 ℃ affinity is maximum. Good drawing and dyeing performance. | ||||||||||||||||||||||||||||
| Direct Blue 15 may be used as a substitute for trypan blue (T895523) for some biological and staining applications. Dyes and metabolites. | |||||||||||||||||||||||||||||
| Definition | ChEBI: An organic sodium salt resulting from the formal condensation of Pontamine sky blue 5B (acid form) with four equivalents of sodium hydroxide. | ||||||||||||||||||||||||||||
| 3,3′-Dimethoxylbenzidine double nitriding, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid(2 Moore) coupled. | |||||||||||||||||||||||||||||
| General Description | Deep purple to dark blue microcrystalline powder. | ||||||||||||||||||||||||||||
| Azo dyes can be explosive when suspended in air at specific concentrations. Soluble in water. | |||||||||||||||||||||||||||||
| Reactivity Profile | DIRECT BLUE 15 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. | ||||||||||||||||||||||||||||
| ACUTE/CHRONIC HAZARDS: When heated to decomposition DIRECT BLUE 15 emits very toxic fumes of nitrogen oxides, sulfur oxides and sodium oxide. | |||||||||||||||||||||||||||||
| Fire Hazard | Flash point data for DIRECT BLUE 15 are not available; however, DIRECT BLUE 15 is probably combustible. | ||||||||||||||||||||||||||||
| A confirmed carcinogen with experimental carcinogenic data reported. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx NazO, and SOx | |||||||||||||||||||||||||||||
| Properties and Applications | blue. Blue powder. Soluble in water solution for the red light blue, solubility of 60 g/L (85 ℃), insoluble in organic solvents. Meet strong sulfuric acid as blue light green, diluted red for blue; Meet nitric acid solution for the red light gray. The dye solution to join strong hydrochloric acid for red light blue precipitation; Add thick sodium hydroxide solution for purple, have precipitation. Cellulose fiber of dyeing, the dye well after sex good, in 60 ~ 80 ℃ maximum of affinity, discharge the gender is good. Copper ions in dyeing color shade darker. Mainly used for cotton, such as glue the cellulose fibre, ?silk and rayon / Kam fabric dyeing, also can be used for pulp, biological, film footage of dyeing, can also be used to make the ink.
