In its most characteristic reaction, AIBN decomposeseliminating a molecule of nitrogen gas to form two 2-cyanopropyl radicals:. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion.

By using this aihn, you agree to the Terms of Use and Privacy Policy. Self-accelerating decomposition may occur if the temperature is not maintained. Personal Protective Equipment Eyes: Never give anything by mouth to an unconscious person.

Another example of a radical reaction that can be initiated by AIBN is the anti-Markovnikov hydrohalogenation of alkenes. This page was last edited on 12 Novemberat Pyrolysis of AIBN without a trap for the formed 2-cyanopropyl radicals results in the formation of tetramethylsuccinonitrilewhich is highly toxic.

May cause degenerative brain changes. Material is sensitive to temperature rises. Avoid contact with eyes, skin, and clothing.

AIBN is produced from acetone cyanohydrin and hydrazinethen followed by oxidation: Remove from exposure to fresh air immediately.

Use water spray to cool fire-exposed containers. Wear appropriate protective clothing to prevent skin exposure. Repeated exposure may cause liver damage.


A respirator dust mask, protective gloves and safety glasses are recommended. Minimize dust generation and accumulation.

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
