TEPA Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
Colorless crystals. Soluble in water, alcohol, and ether. Combustible.
Verwenden
Insect chemosterilant; in dyeing, creaseproofing and flameproofing textiles; stabilizer for polymers; in photographic emulsion hardening.
Verwenden
Used as insect chemosterilant; in dyeing. Antineoplastic.
Definition
ChEBI: Tris(1-aziridinyl)phosphine oxide is a phosphoramide.
Allgemeine Beschreibung
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.
Reaktivität anzeigen
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.
Brandgefahr
Special Hazards of Combustion Products: Phosphoric acid mist may form in fire. Toxic oxides of nitrogen may form.
Sicherheitsprofil
Poison by ingestion, skin contact, intravenous, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic and neoplastigenic data. Human mutation data reported. A corrosive irritant to the skin, eyes, and mucous membranes. When heated to decomposition it emits very toxic fumes of POx and NOx. Used as an acaricide and in the permanentpress treatment of cotton.
