Dear Customer: Hello! Thank you for your continued support for our company. The National Day is coming. In order to allow our employees to enjoy this important holiday, we will make the following adju...
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, known as "wheat pills", typically also contain other chemicals that evolve ammonia which helps to reduce the potential for spontaneous ignition or explosion of the phosphine gas.
AlP is used as both a fumigant and an oral pesticide. 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. In this application, aluminium phosphide can be encountered under various brand names, e.g. Celphos, Fostox, Fumitoxin, Phostek , Phostoxin, Quick Phos, Talunex, Fieldphos, and Weevil-Cide. It generates phosphine gas according to the following hydrolysis equation.
2 AlP + 6 H2O → Al2O3∙3 H2O + 2 PH3It is used as a fumigant when other pesticide applications are impractical and when structures and installations are being treated, such as in ships, aircraft, and grain silos. All of these structures can be effectively sealed or enclosed in a gastight membrane, thereby containing and concentrating the phosphine fumes. Fumigants are also applied directly to rodent burrows.
