2,2'-Azobis(2-methylpropionitrile) Chemical Properties,Uses,Production
Uses
Used as an initiator in the synthesis of highly cross-linked Poly(divinylbenzene) (PDVB) polymers. 1 Used as an initiator in the polymerization process of 2-hydroxyethyl methacrylate (HEMA). 2
Definition
ChEBI: (E)-Azobis(isobutyronitrile) is an azo compound.
General Description
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.
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Reactivity Profile
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.
Hazard
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.
Potential Exposure
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.
Shipping
UN3234 Self-reactive solid type C, temperature controlled materials, Hazard Class: 4.1; Labels: 4.1- Flammable solid, Technical Name Required.
Incompatibilities
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. Azo 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. This chemical is sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents.
