Definition

An amine combining a primary, secondary, and ter- tiary amine in one molecule.

General Description

A colorless liquid with a faint fishlike odor. Flash point 199°F. Corrosive to tissue. Toxic oxides of nitrogen are produced by combustion.

Air & Water Reactions

Water soluble.

Reactivity Profile

N-Aminoethylpiperazine neutralizes acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.

Hazard

Strong irritant to tissue.

Health Hazard

INHALATION: Burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. EYES AND SKIN: Extremely destructive to mucous membranes, upper respiratory tract, eyes and skin. Causes burns on short contact.

Fire Hazard

Special Hazards of Combustion Products: Toxic fumes of NO x

Flammability and Explosibility

Not classified

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion and skin contact. Experimental reproductive effects. A skin and eye irritant. Mutation data reported. See also AMINES. Moderately flammable when exposed to heat, flame, sparks, or powerful oxidlzers. To fight fire, use alcohol foam. When heated to decomposition it emits toxic fumes of NOx,.

Potential Exposure

Used as an epoxy curing agent and making pharmaceuticals; synthetic fibers, and other chemicals.
