Vinyl bromide is used as an intermediate in organic synthesis and for the preparation of plastics by polymerization and copolymerization.

Flame-retarding agent for acrylic fibers.

Industries and functions

Pharmacology

Bromoethene is a colorless, highly flammable gas of brominated hydrocarbon, with a characteristic pungent odor. Bromoethene is mainly used in the production of polymers and copolymers for rubber, plastic, leather and fabricated metal production. Exposure to bromoethene causes dizziness, disorientation, sleepiness. Chronic exposure causes liver and kidney damage. Its metabolites, via cytochrome P450 oxidation, are potent alkylating agents and causes DNA adducts, which is responsible for the carcinogenic effect. Bromoethene is reasonably anticipated to be a human carcinogen. (NCI05)

How it is made

Vinyl bromide can be produced by catalytic addition of hydrogen bromide to acetylene in the presence of mercury &/or copper halide catalysts or by partial dehydrobromination of ethylene dibromide with alcoholic potassium hydroxide.

Prepared by the base-promoted dehydrobromination of ethylene dibromide.
