Aluminum phosphide Usage And Synthesis

Chemical Properties

yellow or grey crystals

Chemical Properties

Aluminum phosphide is a pyrophoric, dark gray or dark yellow crystalline solid

Uses

Source of phosphine; in semiconductor research; as fumigant.

General Description

Aluminum phosphide is a dark gray or dry, yellow, crystalline solid. Aluminum phosphide reacts with moisture to give phosphine, a flammable and poisonous gas. Normally, phosphine will spontaneously ignite upon contact with air. If there is an excess of water, the phosphine fire will not normally ignite any surrounding combustible material.

Air & Water Reactions

Decomposed by water or moist air, evolving phosphine, a toxic gas that often ignites [Merck 11th ed. 1989].

Reactivity Profile

Aluminum phosphide is a reducing agent. Contact with mineral acids causes explosive evolution of toxic phosphine [Wang, C. C. et al., J. Inorg. Nucl. Chem., 1963, 25, p. 327]. Heating produces highly toxic fumes of phosphorus oxides. Can react vigorously upon contact with oxidizing agents. [Sax, 9th ed., p. 119].

Hazard

Dangerous fire risk. It evolves phosphine.

Health Hazard

Acute toxicity occurs primarily by the inhalation route when Aluminum phosphide decomposes into the toxic gas, phosphine. The human median lethal dose for Aluminum phosphide has been reported to be 20 mg/kg. Rated as super toxic: probable oral lethal dose is less than 5 mg/kg or less than 7 drops for a 70 kg (150 lb.) person.

Fire Hazard

Releases toxic fumes on exposure to moist air, water, or acids. Decomposes to produce phosphine gas. Avoid water, dilute mineral acids, dilute or concentrated hydrochloric acid. Stable when dry. Avoid moist air.

Agricultural Uses

Fumigant, Fungicide, Rodenticide, Insecticide: Used as an insecticidal fumigant for grain, peanuts, processed food, animal feed, leaf tobacco, cottonseed, and as space fumigant for flour mills, warehouses and railcars. It is also used in baits for rodent and mole control in crops. Used as a source of phosphine; in semiconductor research. Zinc phosphide is often mixed with bait food such as cornmeal, which can be a danger to pets and children. When phosphides are ingested or exposed to moisture, they release phosphine gas. A U.S. EPA restricted Use Pesticide (RUP). Metallic phosphides on clothes, skin, or hair can react with water or moisture to generate phosphine gas.

Safety Profile

A human poison by inhalation and ingestion. Dangerous; in contact with water, steam, or alkali it slowly yields PH3, which is spontaneously flammable in air. Explosive reaction on contact with mineral acids produces phosphine. When heated to decomposition it yields toxic PO,. See also ALUMINUM COMPOUNDS, PHOSPHIDES, and PHOSPHINE. AHGOOO

Potential Exposure

Used as a rodenticide; wood preservative; as a source of phosphine; as an insecticidal fumigant for grain, peanuts, processed food, animal feed, leaf tobacco, cottonseed; and as space fumigant for flour mills, warehouses and railcars. Used in semiconductor research

Shipping

UN1397 Aluminum phosphide, Hazard Class: 4.3; Labels: 4.3-Dangerous when wet material, 6.1-Poisonous materials.

Incompatibilities

Able to ignite spontaneously in moist air; forms toxic and explosive phosphine gas on contact with moisture in air. Reacts violently with water, steam, carbon dioxide; acids, alcohols, and foam fire extinguishers. Contact with water and bases slowly releases highly flammable and toxic phosphine gas.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Allow to react slowly with moisture in the open, being sure that phosphine gas evolved is dissipated. Alternatively, mix with dry diluent and incinerate at temperature above 1000 C with effluent gas scrubbing. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed of properly by following package label directions or bycontacting your local or federal environmental control agency, or by contacting your regional EPA office.
