General Description
Boiling point 60°F. Liquid at low ambient temperatures. Specific gravity 1.51. A suspected carcinogen. Under exposure to fire or heat containers may rupture violently and rocket.
Reactivity Profile
VINYL BROMIDE is a light sensitive, peroxidizable monomer may initiate exothermic polymerization of the bulk material [Handling Chemicals Safely 1980.. p. 958]. VINYL BROMIDE, INHIBITED(593-60-2) will react violently with oxidants.
Air & Water Reactions
Highly flammable, with air forms peroxides
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Some may be toxic if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.
Potential Exposure
Vinyl bromide is used as an intermediate
in organic synthesis and for the preparation of plastics
by polymerization and copolymerization; as a comonomer
with acrylonitrile and other vinyl monomers in modacrylic
fibers; in the production of flame-retardant synthetic fibers.
Fire Hazard
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Silane will ignite spontaneously in air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Shipping
UN1085 Vinyl bromide, stabilized, Hazard
Class: 2.1; Labels: 2.1-Flammable gas. Cylinders must be
transported in a secure upright position, in a well-ventilated
truck. Protect cylinder and labels from physical damage.
The owner of the compressed gas cylinder is the only entity
allowed by federal law (49CFR) to transport and refill
them. It is a violation of transportation regulations to refill
compressed gas cylinders without the express written permission
of the owner.
Incompatibilities
Vinyl bromide is a dangerous chemically
unstable compound that may polymerize spontaneously in
heat, sunlight and possibly exposure to UV. Dangerously
reactive with oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.);
contact may cause fires or explosions. Keep away from
alkaline materials, acetylene, strong acids, strong bases,
copper compounds. Add 0.1% phenol to gas to prevent
polymerization.
Chemical Properties
colourless liquid
Chemical Properties
Vinyl bromide is a colorless gas or liquid at
low ambient temperature. Pleasant odor. Shipped as a liquefied
compressed gas with 0.1% phenol added to prevent
polymerization.
Waste Disposal
Return refillable compressed
gas cylinders to supplier. Nonrefillable cylinders should be
disposed of in accordance with local, state and federal regulations.
Allow remaining gas to vent slowly into atmosphere
in an unconfined area or exhaust hood. Refillabletype
cylinders should be returned to original supplier with
any valve caps and outlet plugs secured and valve protection
caps in place.
Uses
Production of flame-resistant plastics
or thermoplastic resins.
Uses
Vinyl bromide is used as a fire retardant inplastics.
Definition
ChEBI: Bromoethene is a monohaloethene and a bromoalkene.
Production Methods
VB can be produced by the catalytic addition of hydrogen
bromide to acetylene in the presence of mercury and
copper halide catalysts or by partial dehydrobromination
of ethylene dibromide with alcoholic potassium
hydroxide.
Carcinogenicity
Vinyl bromide is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
Toxics Screening Level
The Initial Threshold Screening Level (ITSL) for vinyl bromide is 30 μg/m3 with an annual averaging time.
