Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4).

磷化氢，是一种无机化合物，化学式为ph3，是一种无色、剧毒、易燃的储存于钢瓶内的液化压缩气体。 纯净的磷化氢气体是无色无味的，但在金属磷化物产生磷化氢气体时常带有乙炔味或者大蒜味或者腐鱼味。

Phosphine is a colorless, flammable, and explosive gas at ambient temperature that has the odor of garlic or decaying fish. Small amounts occur naturally from the break down of organic matter. It is slightly soluble in water .

phosphine (PH 3), 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 (Ca 3 P 2 ).

Phosphine gas was discovered by Philippe Gengembre in 1783. Gengembre made it by the action of caustic soda on phosphorus. It is chemical formula PH3. Phosphides – When calcium and sodium Phosphides reacts with water, phosphine gas is obtained. Phosphine gas is also obtained by the action of dilute sulfuric acid from aluminium phosphide.

2023年12月20日 · Phosphine, or Phosphorous trihydride, is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. It is one of the most commonly used fumigants globally for the disinfestation of cereal grains, legumes, seeds, dried fruit, tree nuts, other durable food commodities, and many processed foods[1].

Phosphorus trihydride (PH3) – most commonly known as phosphine – is mainly used for fumigation applications because of biocide properties – required for international transport. Phosphine is also industrially released while producing acetylene, during metals de-rusting process with phosphoric acid or in metal treatment plants with phosphides.

Phosphine is a super- toxic gas with a probable oral lethal dose of 5 mg/kg or 7 drops for a 150 pound person. An air concentration of 3 ppm is safe for long term exposure, 500 ppm is lethal in 30 minutes, and a concentration of 1,000 ppm is lethal after a few breaths.
