Phosphine application rate
WebPhosphine (PH3). A colorless, odorless gas having a low molecular weight, low boiling point, and specific gravity of 1.21 in relation to air. The gas diffuses rapidly and is capable of penetrating deeply into materials, such as bulk grains. Phosphine is flammable at concentrations above 1.79 percent by volume in air. Recirculation. WebHigh pressure fans present a risk of phosphine combustion and hence fire. 9.The current recommended dosage rate for phosphine is 2g of gas/ton or 1.5g of gas/m3(3g of aluminum phosphide = 1g of phosphine gas). However, recommendations do change and it is important to check them from time to time.

Webphosphine (PH3), also called hydrogen phosphide, a colourless, flammable, extremely toxic gas with a disagreeable garliclike odour. Phosphine is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca3P2). Phosphine is structurally similar to ammonia (NH3), but phosphine is a much … WebCommercial grade phosphine containing diphosphines can ignite and form explosive mixtures at concentrations exceeding 1.8% phosphine in air. The rate of conversion of the phosphide to phosphine is temperature and humidity dependent. Similarly, metal phosphides readily hydrolyze in water to yield phosphine, which is poorly soluble in water.
