使用

Intermediate, especially for dyes.

調製方法

Nitration of chlorobenzene with mixed acid (30/56/14) typically gives an isomer mix in 98 % yield consisting of 34 – 36 % 2-Nitrochlorobenzene, 63 – 65 % 4- chloronitrobenzene, and only ca. 1 % 3- chloronitrobenzene. The ortho – para ratio of about 0.55 is in sharp contrast to the 1.6 obtained with nitrotoluene isomers. As with the nitration of toluene, much work has been done on isomer control so that the producer might have some flexibility towards the balance of isomer demand. Although no major change in ratio has been achieved, the situation is better for nitrochlorobenzene than nitrotoluenes, because the favored isomer is in much greater demand. In further contrast to the nitration of toluene, the nitration of chlorobenzene in the presence of phosphoric acid decreases the proportion of 4-Nitrochlorobenzene, and the use of phosphoric acid in the presence of a transition-metal catalyst is said to increase the ortho – para ratio to ca. 0.8.

一般的な説明

Yellow crystals with an aromatic odor. Sinks in water.

空気と水の反応

2-Nitrochlorobenzene may be sensitive to prolonged exposure to air and light. Insoluble in water.

反応プロフィール

O-NITROCHLOROBENZENE is incompatible with strong bases and strong oxidizing agents. 2-Nitrochlorobenzene will react with ammonia.

危険性

Toxic by inhalation and ingestion. Combustible. Questionable carcinogen.

健康ハザード

INHALATION: Headache, languour, anemia. Irritation of nose and throat, cyanosis, shallow respiration, convulsions, and coma. EYES: Irritation. SKIN: Irritation. INGESTION: Forms methemoglobin giving rise to cyanosis and blood changes.

安全性プロファイル

Suspected carcinogen with experimental carcinogenic and neoplastigenic data. Poison by ingestion, skin contact, and probably inhalation. Combustible when exposed to heat or flame. To fight fire, use water, foam. Potentially explosive reaction with ammonia at 160℃/30 bar. When heated to decomposition it emits toxic fumes of Cl-, NOx, and phosgene.

純化方法

Crystallise it from EtOH, MeOH or pentane (charcoal). [Beilstein 5 IV 721.]
