2-Nitrochlorobenzene Usage And Synthesis

Chemical Properties

yellow solid with a characteristic odour

Uses

Intermediate, especially for dyes.

General Description

Yellow crystals with an aromatic odor. Sinks in water.

Air & Water Reactions

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

Reactivity Profile

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

Hazard

Toxic by inhalation and ingestion. Combustible. Questionable carcinogen.

Health Hazard

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.

Safety Profile

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. See also other chloronitrobenzene entries and NITRO COMPOUNDS of AROMATIC HYDROCARBONS.

Purification Methods

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