SUDAN II Chemical Properties,Uses,Production
Chemical Properties
Red to orange-brownish powder
Uses
Sudan II is a fat soluble red synthetic azo dye. Sudan II is reduced to potentially carcinogenic aromatic amines by human intestinal bacteria. Dyes and metabolites, Environmental Testing.
Preparation
mixed N,N-dimethylaniline diazotization, and Naphthalen-2-ol coupling.
Definition
ChEBI: Sudan II is a member of azobenzenes.
General Description
Red crystals. Insoluble in water.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity Profile
SUDAN II is an azo compound. Toxic gases are formed by mixing azo compounds 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.
Flammability and Explosibility
Not classified
Safety Profile
Questionable carcinogen with experimental carcinogenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
Properties and Applications
red orange. Melting point 166 ℃ (from the glacial acetic acid crystallization out). Soluble in ethanol, acetone and benzene as the red orange. In concentrated sulfuric acid for cherry red, dilution still for cherry red, and then into the orange and red brown with precipitation; In concentrated nitric acid for brilliant orange solution, and then gradually become dark; In 10% of sodium hydroxide solution insoluble, for yellow sanguine. Dye alcohol solution to join concentrated hydrochloric acid for orange solution; Add sodium hydroxide to become red.
