Chemische Eigenschaften
red-brown crystalline powder
Verwenden
Coloring oils, fats and waxes; manufacture of pigments. Chemical intermediate for the production of dyes.
synthetische
(a) will Sodium nitrite (1 Moore) to join O-Methylaniline (8.5 Moore) and hydrochloric acid (1 Moore), the temperature is maintained at 28 ℃ below, until diazotization finish. Add a small amount of hydrochloric acid (about 0.2 Moore), and heating (40 ℃, 3 hours), in order to separate, with Sodium hydroxide for mercerization, and distillation reservoir. In order to get the refined products, usable alcohol recrystallization; (b) O-Methylaniline?diazotization, and O-Methylaniline?base Methanesulfonic acid coupling, and then with Sodium hydroxide solution common boiling, hydrolysis off Methanesulfonic acid base.
Allgemeine Beschreibung
Reddish-brown to golden crystals; orangish red powder. Odorless.
Air & Water Reaktionen
Dust may form an explosive mixture in air. Insoluble in water.
Reaktivit?t anzeigen
O-AMINOAZOTOLUENE 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. O-AMINOAZOTOLUENE is sensitive to prolonged exposure to heat. O-AMINOAZOTOLUENE is incompatible with strong oxidizing agents.
Hazard
Possible carcinogen.
Brandgefahr
Flash point data for O-AMINOAZOTOLUENE are not available. O-AMINOAZOTOLUENE is probably combustible.
Sicherheitsprofil
Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by ingestion. Moderately toxic by subcutaneous route. An experimental teratogen. Human mutation data reported. When heated to decomposition it emits toxic fumes of NO,. See also AROMATIC AMINES.
m?gliche Exposition
An azo compound used in dyes, medicines; as a colorant in shoe polishes and other wax-based polishes.
Carcinogenicity
o-Aminoazotoluene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
