| Acid Violet 49 Usage And Synthesis |
| Chemical Properties | powder | | Uses | Benzyl Violet is an impuriy of α,α-Bis[4-(dimethylamino)phenyl]-4-(methylamino)-benzenemethanol which is a product from degradation of methyl green. | | General Description | Fine black powder. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Acid Violet 49 neutralizes acids in weakly exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. | | Hazard | Possible carcinogen. | | Health Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition Acid Violet 49 emits very toxic fumes of nitrogen oxides, ammonia, sodium oxide and sulfur oxides. | | Fire Hazard | Flash point data for Acid Violet 49 are not available; however, Acid Violet 49 is probably combustible. | | Safety Profile | Confirmed carcinogen
with experimental carcinogenic and
tumorigenic data. Mutation data reported.
When heated to decomposition it emits very
toxic fumes of NOx, NH3, Na2O, and SOx. | | Properties and Applications | bright blue purple. Violet powder. It is easy to dissolve in the cold water and hot water (purple), soluble in ethanol (purple). Strong sulfuric acid in orange, diluted mustard color. Add sodium hydroxide solution for the dark precipitation. Mainly used for wool, silk, polyamide fiber dyeing, spelling color performance is good, refined as food after dye.
