Stability
Unstable - inhibitors such as propylene oxide or trimethylamine
are usually added to prevent polymerization. Combustible. Incompatible with strong oxidizing agents,
water, acids, most common metals, dimethyl sulfoxide.
Above flash point vapour-air
mixtures are explosive within the limits noted above. Contact with water produces
toxic fumes.
