繊維難燃剤原料
化学的特性
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.
使用
Vinyl bromide is used as a fire retardant inplastics.
調製方法
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.
一般的な説明
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.
空気と水の反応
Highly flammable, with air forms peroxides
反応プロフィール
VINYL BROMIDE is a light sensitive, peroxidizable monomer may initiate exothermic polymerization of the bulk material [Handling Chemicals Safely 1980.. p. 958]. Vinyl bromide will react violently with oxidants.
健康ハザード
Inhalation of this gas at high concentrationscan produce anesthesia and kidney damage.Exposure to 2.5% concentration in air pro duced anesthetic effects in rats. A 15-minuteexposure to 10% concentration was fatal torats (ACGIH 1986). Kidney injury occurredat a 5% exposure level. Human toxicity datafor this compound are not available. The liq uid is mild to moderately irritating to theeyes.
Vinyl bromide manifested carcinogenicproperties in laboratory animals. It producedliver and blood tumors in rats and mice.Its cancer-causing effects in humans arenot known. However, on the basis of itssimilarity to vinyl chloride, it is suspectedto be a human carcinogen.
火災危険
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.
安全性プロファイル
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data.
Moderately toxic by ingestion. Mutation data
reported. A very dangerous fire hazard when
exposed to heat or flame. Can react violently
with oxidzing materials. May polymerize in
sunlight. To fight fire, use CO2, dry
chemical, or water spray. When heated to
decomposition it emits toxic fumes of Br-.

CHLORIDE.
職業ばく露
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.
発がん性
Vinyl bromide is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
輸送方法
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.
不和合性
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.
廃棄物の処理
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.
