Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

Bromobenzene Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Uses

In organic synthesis, especially to make phenyl magnesium bromide; as solvent, especially for crystallizations on a large scale and where a heavy liquid is desirable; as additive to motor oils.

General Description

Mobile clear colorless liquid with a pungent odor. Flash point 124°F. Denser than water and insoluble in water. Hence sinks in water. Vapors are heavier than air. A skin irritant.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

Bromobenzene may be sensitive to light. May react with oxidizing agents .

Hazard

Skin irritant. Moderate fire risk.

Health Hazard

Contact with liquid causes irritation of eyes and mild irritation of skin. Ingestion causes mild irritation of mouth and stomach.

Health Hazard

The acute toxicity of bromobenzene is lowin test animals. The toxic symptoms includesomnolence, respiratory stimulation, and muscle contraction. The oral LD50 value in rats is2700 mg/kg.

Fire Hazard

Flash Point (°F): 124 ℃; Flammable Limits in Air (%): Not pertinent; Fire Extinguishing Agents: Water, dry chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Irritating hydrogen bromide and other gases form in a fire situation; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 1,049; Electrical Hazard: No data; Burning Rate: 3.8 mm/min.

Fire Hazard

Special Hazards of Combustion Products: Irritating hydrogen bromide and other gases may be produced in fire.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Moderately toxic by ingestion, subcutaneous, and intraperitoneal routes. LWdly toxic by inhalation. An eye and mucous membrane irritant. Mutation data reported. Flammable liquid when exposed to heat, sparks, or flame. Can react with oxidtzing materials. To fight fire, use water to blanket fire, foam, CO2, water spray or mist, dry chemical. Violent reaction with bromobutane + sodium when heated above 30℃. When heated to decomposition it emits toxic fumes of Br-. See also BROMIDES.

Metabolic pathway

Bromobenzene and chlorobenzene are metabolized by human and mouse hepatic microsomes to two different epoxide intermediates, which rearrange to form either o- or p-bromo- and o- or p-chlorophenols, respectively. Humans preferentially metabolize halobenzenes through the hepatotoxic 3,4-epoxide pathway, suggesting that humans may be more susceptible than mice to halobenzene-induced hepatotoxicity.

Purification Methods

Wash bromobenzene vigorously with conc H2SO4, then 10% NaOH or NaHCO3 solutions, and H2O. Dry it with CaCl2 or Na2SO4, or pass it through activated alumina, before refluxing with, and distilling from, CaH2, using a glass helix-packed column. [Beilstein 5 IV 670.]
