Phosphine History

Phosphine was once regarded as a gaseous form of the element because of its strong association with elemental phosphorus,but Lavoisier (1789) recognised it as a combination of phosphorus with hydrogen by describing it as "hydruyet of phosphorus, or phosphuret of hydrogen"
Later Ernst von Meyer (1891) described the early history of phosphine research thus: "The discovery of phosphuretted hydrogen (PH₃) by Gengembre in 1783, and the examination of it by Pelletier (who was the first to prepare it pure), only became fruitful after Humphry Davy's investigations; and the last-named elucidated the composition of this gas, and pointed out its analogy to ammonia, this being emphasised still more sharply by H. Rose later on."
Then Thénard (1845) used a cold trap to separate diphosphine from phosphine which had been generated from calcium phosphide, so that demonstrating that P₂H₄ is responsible for spontaneous flammability associated with PH₃, and also for the characteristic orange/brown colour that can form on surfaces, which is a polymerisation product. He considered diphosphine's formula to be PH₂, and thus an intermediate between elemental phosphorus, the higher polymers, and phosphine.

Phosphine Uses

Phosphine is commonly used for semiconductor manufacturing.

Phosphine Production

Industrially Phosphine can be made by the reaction of white phosphorus with sodium hydroxide, producing sodium hypophosphite and sodium phosphite as a by-product.

Phosphine Specification

Phosphine (CAS NO.7803-51-2) is also named as CCRIS 8578 ; ECO2FUME ; Fosforowodor ; Fosforowodor [Polish] ; Gas-Ex-B ; HSDB 1233 ; Hydrogen phosphide ; Phosphine (fumigant) ; Phosphoretted hydrogen ; Phosphorus hydride ; Phosphorus trihydride ; Phosphorwasserstoff ; Phosphorwasserstoff [German] ; RCRA waste number P096 ; UN 2199 . Phosphine (CAS NO.7803-51-2) is colourless gas. It is highly flammable. It usually ignites spontaneously in air. It is insoluble in water. Phosphine is a reducing agent. Liquefied Phosphine can be detonated. Forms explosive mixtures with even small amounts of oxygen. Ignites or reacts violently with boron trichloride, dichlorine oxide, halogens (bromine, chlorine, iodine), metal nitrates, nitrogen oxides, nitric acid, nitrous acid, nitrogen trichloride. Phosphine is a super- toxic gas. 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. Phosphine can explode with powerful oxidizers. The gas is heavier than air and may travel along the ground to an ignition source. Container may explode in heat of fire. Phosphine emits highly toxic fumes of phosphorus oxides when heated to decomposition. It may become unstable at high temperatures.
