β - Bromobenzene: also known as β - bromoethylbenzene, 2-phenylbromoethane, 2-bromoethylbenzene, molecular formula: C8H9Br, relative molecular weight: 185.07, colorless and transparent liquid, boiling point 220-221 ℃, relative density: 1.3589, refractive index: 1.5572, flash point: 89 ℃, miscible with ether and benzene, insoluble in water. Toxic. Skin contact: Immediately remove contaminated clothing and rinse with plenty of water. Eye contact: Immediately lift the eyelids and rinse with plenty of flowing water. During the rinsing process, continuously rotate the eyes and rinse for at least 20 minutes. Fire hazards shall be eliminated during leakage, and personnel shall be evacuated. In case of small leakage, inert materials such as sand can be used to absorb it. In case of large leakage, insoluble foam shall be used to cover it, so as to avoid large volatilization and combustion explosion.

Swallowing is harmful, skin contact is harmful, and inhalation is harmful.

Preventive measures
▷ Wear protective gloves, protective clothing, goggles, and masks

Thoroughly clean after homework and do not discharge into the environment.

Accident Response
