fosfaane

Fosfaane is the French word for phosphine, a chemical compound with the formula PH3. It is a colorless, flammable, and highly toxic gas that has a strong, unpleasant odor, often described as resembling garlic or decaying fish. Phosphine is an inorganic compound and is the simplest phosphide of hydrogen.

Industrially, phosphine is produced through several methods, including the reaction of white phosphorus with strong bases like sodium hydroxide or potassium hydroxide, or by the hydrolysis of metal phosphides. It is used in various applications, most notably as a fumigant to control pests in stored grains and tobacco. Its ability to penetrate materials and kill insects at all life stages makes it effective for this purpose.

Phosphine also finds use as a dopant in the semiconductor industry and as a reagent in organic synthesis. However, its extreme toxicity necessitates careful handling and strict safety protocols. Exposure to phosphine can cause severe respiratory distress, neurological damage, and can be fatal. Due to its flammability and toxicity, phosphine is stored and transported under controlled conditions. The chemical properties of phosphine include its basic nature and its tendency to oxidize readily in air.
