ALUMINIUM PHOSPHIDE
1) Common name: Aluminium Phosphide
2) Synonyms: Aluminium(III) phosphide; Aluminium monophosphide; Phostoxin; Fumitoxin
3) Chemical name: Aluminium monophosphide
4) CAS Number: 20859-73-8
5) Empirical formula:AlP
6) Molecular weight: 57.95
7) Structural formula:
8) Physical & Chemical Properties:
a. Appearance: Dark grey or yellowish crystals, has an odor similar to garlic or decaying fish.
b. Melting point: 2530 °C
c. Vapor pressure: negligible at 25 °C
d. Bulk density:2.85 g/cm³, solid
e. Solubility:Insoluble; reactive with water to form hydrogen phosphide (phosphine), H3P
9) Stability: Hydrogen phosphide (phosphine) gas, produced by reaction with aluminum phosphide in contact with water (even at ambient humidity), reacts with moist air, vilolently with acids, producing phosphine.
10) Application:AlP is used as a rodenticide, insecticide, and fumigant for stored cereal grains. It is used to kill small verminous mammals such as moles, and rodents. The tablets or pellets typically also contain other chemicals that evolve ammonia which helps to reduce the potential for spontaneous ignition or explosion of the phosphine gas. As a rodenticide, aluminium phosphide pellets are provided as a mixture with food for consumption by the rodents. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas. Other pesticides similar to aluminium phosphide are zinc phosphide and calcium phosphide.
