Of other phosphorus compounds we may here notice Gengembre's discovery of phosphuretted hydrogen (phosphine) in 1783, the analogy of which to ammonia was first pointed out by Davy and supported at a later date by H.
Phenyl-acridine is the parent base of chrysaniline, which is the chief constituent of the dyestuff phosphine (a bye-product in the manufacture of rosaniline).
They Are Removed By Passing The Vapours In Succession Through Concentrated Solutions Of The Caustic Alkalis, Concentrated Sulphuric Acid, And Triethyl Phosphine; The Residual Gas Is Then Purified By Liquefaction (W.
When finely divided it decomposes water giving hydrogen phosphide; it also reduces sulphurous and sulphuric' acids, and when boiled with water gives phosphine and hypophosphorous acid; when slowly oxidized under water it yields, hypophosphoric acid.
Phosphine (phosphoretted hydrogen), PH 31 a gas formed in the putrefaction of organic matter containing phosphorus, was obtained by Gengembre (Crell's Ann., 1789, i.
