WebPhosphine is a chemical which belongs to the group of organophosphorus compounds. This compound was first obtained by Philippe Gengembre in the year 1783. He obtained phosphine by supplying heat to phosphorus in an aqueous solution of potassium carbonate. The chemical formula of this compound is PH3. Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, 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). With traces of P2H4 present, PH3 is spontaneously flammable in air (
