TEPA Chemical Properties,Usage,Production

Chemical Properties
colourless granules

Usage
Used as insect chemosterilant; in dyeing. Antineoplastic.

General Description
An aqueous solution of a colorless crystalline solid. Toxic by skin absorption, ingestion or inhalation. Produces toxic oxides of nitrogen during combustion. Used as a pesticide.

Reactivity Profile
TRIS-(1-AZIRIDINYL) PHOSPHINE OXIDE may react with aqueous solutions of acids or strong bases. Undergoes slow decomposition in water, not considered hazardous. Polymerizes violently at about 255°F. Acid fumes also cause polymerization at ordinary temperatures [USCG, 1999]. May produce highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Health Hazard
Inhalation (unlikely unless a heavy mist is formed) causes symptoms similar to those observed after ingestion. Contact with liquid or powder causes irritation of eyes and (on prolonged contact) irritation and burns of skin. Burns are slow to develop and slow to heal. May sensitize on repeated contact. Ingestion causes depression, anorexia, and diarrhea, appearing 2-3 days before death, followed by terminal dyspnea, incoordination, epistaxis, salivation, prostration and cyanosis.

Fire Hazard
Special Hazards of Combustion Products: Phosphoric acid mist may form in fire. Toxic oxides of nitrogen may form.
