NFPA 704

Diamond Hazard Value Description
Flammability   2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
Instability   1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

Dimethylaminopropionitrile Chemical Properties,Uses,Production

Chemical Properties

clear colorless liquid

General Description

Colorless liquid. Mp: -44.3°C; bp: 171-172°C. Density 0.87 g cm-3 at 20°C). Water-soluble. Used in the manufacture of polyurethane foam. Excessive exposure leads to urologic and neurologic disorders.

Reactivity Profile

Dimethylaminopropionitrile is combustible but non-flammable (flash point > 140°F), reacts with oxidizing agents (Hazardous Chemicals Desk Reference, p. 426 (1987)). Reacts violently with LIAlH4, a strong reducing agent. Emits toxic oxides of nitrogen and cyanide fumes when heated to decomposition.

Safety Profile

Poison by intravenous route. Moderately toxic by ingestion and skin contact. A skin and eye irritant. Flammable liquid when exposed to heat, flame, or oxidizers; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of NOx and CN-. See also NITRILES.
