Referred to as AIBN. Soluble in organic solvents such as methanol, ethanol, ether, acetone, petroleum ether and aniline. When exposed to heat, nitrogen and organic cyanide containing -(CH2)2-C-CN groups are liberated. The decomposition temperature is 64°C. It decomposes slowly at room temperature and rapidly decomposes at 100 ℃. Can cause explosion and fire, flammable. poisonous. The released organic cyanide is more harmful to the human body.
White crystal or crystalline powder, insoluble in water, soluble in ether, methanol, ethanol, propanol, chloroform, dichloroethane, ethyl acetate, benzene, etc., mostly oil-soluble initiators. Decomposes when exposed to heat, with a melting point of 100°C-104°C. It should be stored in a dry place at 20°C. In contact with moisture, nitrogen and organic cyanide containing -(CH2)2-C-CN groups are liberated. The decomposition temperature is 64℃. It decomposes slowly at room temperature, and rapidly decomposes at 100℃, which can cause explosion and fire, which is flammable and toxic. Emit nitrogen and organic cyanide, the latter is more harmful to the human body.
Application features
Azobisisobutyronitrile is an oil-soluble azo initiator. The azo initiator has a stable reaction. It is a first-order reaction without side reactions and is relatively easy to control. Therefore, it is widely used in the research and production of polymers. Such as vinyl chloride, vinyl acetate, acrylonitrile and other monomer polymerization initiators, can also be used as polyvinyl chloride, polyolefin, polyurethane, polyvinyl alcohol, acrylonitrile and butadiene and styrene copolymer, polyisocyanate, polyacetate Blowing agent for vinyl ester, polyamide and polyester. In addition, it can also be used in other organic synthesis.
Product Usage
Used as a polymerization initiator for monomers such as polyvinyl chloride, polyvinyl alcohol, polystyrene, polyacrylonitrile, etc.; as an initiator for the polymerization of monomers such as vinyl chloride, vinyl acetate, acrylonitrile, etc., as well as for rubber and plastics Foaming agent, the dosage is 10%-20%. This product can also be used as a vulcanizing agent, pesticide and intermediate for organic synthesis. This product is a highly toxic substance. It is LD5017.2-25mg/kg orally for mice. The organic cyanide liberated by heat is more toxic to the human body. ;Intermediate for organic synthesis;used as initiator of high molecular polymer
Storage and transportation method
Treasury is ventilated, low temperature and dry; stored separately from oxidants
Safety instructions
Overview of dangers

【Explosion hazard】This product is flammable and irritating.
First aid measures
【Skin contact】Take off contaminated clothing and rinse the skin thoroughly with soap and water. Seek medical attention.
[Eye contact] Lift the eyelids and rinse with running water or normal saline. Seek medical attention.
【Inhalation】Quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If you have difficulty breathing, seek medical attention immediately.
【Ingestion】Ingestion by mistake, seek medical attention immediately.
Fire-fighting measures
[Hazard characteristics] When exposed to high heat, open flames or mixed with oxidants, there is a danger of combustion and explosion due to friction or impact. When it burns, it emits toxic gas. It is unstable when heated. It decomposes gradually at 40℃, and decomposes violently at 103~104℃. It releases nitrogen and several organic cyanide compounds, which are harmful to the human body and emit large amounts of heat, which can cause an explosion.
[Hazardous combustion products] Carbon monoxide, carbon dioxide, cyanide, nitrogen oxides, nitrogen.
[Fire fighting method] Move the container from the fire scene to an open place as much as possible. Spray water to keep the fire container cool until the end of the fire extinguishing. Extinguishing agent: water, foam, carbon dioxide, dry powder, sand.
Leakage emergency response
[Emergency treatment] Isolate the leaking contaminated area and restrict access. Cut off the source of leakage immediately, cool the container, and move out of the accident area. Emergency personnel should wear safety protection equipment. Do not directly touch the leakage. Wet with water, use non-sparking tools to collect in a closed plastic bucket or cardboard bucket. The leakage site, cleaning wastewater, contaminated products, emergency treatment equipment, etc. should be treated in a harmless manner to meet environmental protection requirements.
[Engineering control] Airtight operation, local exhaust.
[Respiratory protection] When you may come into contact with poisons, you should wear a filter-type dust-proof respirator. It is recommended to wear self-contained breathing apparatus during emergency rescue or evacuation.
[Eye protection] Wear safety glasses.
【Body protection】Penetrating gas type anti-virus suit.
[Hand protection] Wear anti-poisonous penetration gloves.
[Other protection] After work, take a shower and change clothes. Store clothes contaminated by poisons separately and wash them for later use.
