Solvent Orange 2 Chemical Properties,Uses,Production
Chemical Properties
red needles or powder
Uses
1-o-Tolueneazo-2-naphthol is a potent cytochrome P-488 inducer. Dyes and metabolites.
Definition
ChEBI: Oil Orange SS is a member of azobenzenes.
Preparation
O-Methylaniline diazotization, and Naphthalen-2-ol coupling.
General Description
Red needles or orange powder. Sublimes above 374°F.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity Profile
Solvent Orange 2 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 Solvent Orange 2 are not available; however Solvent Orange 2 is probably combustible.
Safety Profile
Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Poison by intravenous route. Mildly toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used to color cosmetics, varnishes, oils, fats and waxes, petroleum products.
Properties and Applications
red orange. From the glacial acetic acid in the products crystallization for red crystal, its melting point is 131 ℃. Slightly soluble in ethanol for orange red solution, slightly soluble in acetone and benzene. In concentrated sulfuric acid to red light purple, dilution after big red, and the red precipitation; In concentrated nitric acid for red solution and then into orange. Dye alcohol solution with dilute hydrochloric acid, color slightly changed; With dilute sodium hydroxide solution for brown light orange. It is mainly used in oil product color, also used for ink and cultural and educational supplies coloring.
