정의
ChEBI: (E)-Azobis(isobutyronitrile) is an azo compound.
일반 설명
Insoluble in water and denser than water. Moderately toxic by ingestion. Readily ignited by sparks or flames. Burns intensely and persistently. Toxic oxides of nitrogen produced during combustion. Used as a catalyst, in vinyl polymerizations and a blowing agent for plastics.
공기와 물의 반응
Dust may form an explosive mixture in air. Insoluble in water.
반응 프로필
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. Self-accelerating decomposition may occur if the specific control temperature is not maintained. These materials are particularly sensitive to temperature rises. 2,2'-Azobis(2-methylpropionitrile) is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
위험도
Toxic by ingestion.
Safety Profile
Poison by
intraperitoneal route. Moderately toxic by
ingestion. Easily oxidized, unstable. Violent
exothermic decomposition when heated.
Solution in acetone may decompose
explosively. Explodes when heated with
heptane. When heated to decomposition it
emits toxic fumes of NO, and CN-. See also
NITRILES. A free-radcal generator.
잠재적 노출
Azobisisobutylonitrile is both a nitrile
and azo compound. Used as a polymerization initiator, free
radical generator (or initiator); as a catalyst in vinyl polymerizations;
as a blowing agent for elastomers and plastics.

비 호환성
Flammable; dust may form explosive
mixture with air. Unstable and easily oxidized material;
keep away from oxidizers, strong acids. Keep at temperature
not ≧30° C (this may vary by manufacturer). Risk of
explosion from heat, shock, friction. Warming causes production
of tetramethylsuccinonitrile and cyanide fumes.
Keep away from acetone and other ketones, alcohols, lithium,
aluminum, aldehydes, and hydrocarbons, such as heptane.

combination can occur with strong oxidizing agents, metal
salts, peroxides, and sulfides. This chemical is sensitive to
prolonged exposure to heat. This chemical is incompatible
with strong oxidizing agents.
