製造方法
(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.
一般的な説明
Reddish-brown to golden crystals; orangish red powder. Odorless.
空気と水の反応
Dust may form an explosive mixture in air. Insoluble in water.
反応プロフィール
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.
危険性
Possible carcinogen.
火災危険
Flash point data for O-AMINOAZOTOLUENE are not available. O-AMINOAZOTOLUENE is probably combustible.
安全性プロファイル
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.
職業ばく露
An azo compound used in dyes, medicines; as a colorant in shoe polishes and other wax-based polishes.
発がん性
o-Aminoazotoluene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
輸送方法
