| Hazard Information | Back Directory | [General Description]
Fine black powder. | [Reactivity Profile]
BENZYL VIOLET 4B(1694-09-3) 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. | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Possible carcinogen. | [Health Hazard]
ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits very toxic fumes of nitrogen oxides, ammonia, sodium oxide and sulfur oxides. | [Fire Hazard]
Flash point data for this chemical are not available; however, BENZYL VIOLET 4B is probably combustible. | [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. | [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.
