Structure

Properties

Appearance    (1), transparent liquid; (2), solid.

Solubility    soluble in water.

Stability    stable. Easy self-polymerization. Under hot strong acid or hot strong alkali, easily hydrolyze. Easily oxidized. Under alkaline conditions, release ammonia.

Risk    Solid form: flammable material; irritation, irritation to skin, eye, respiratory. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.

GHS (Rev.10) label:  

Liquid form: corrosion; irritation, irritation to skin, eye.

GHS (Rev.10) label: 

Ecology    may be hazardous to environment. Water body should be given special attention.

Biodegradability    biodegradable.

Characteristics    excellent film-forming, dispersing abilities.

Synthesis

Acrylonitrile, fuming sulfuric acid react with isobutylene, neutralizes by ammonia, then obtain.
