Spontaneous human combustion possible? Questions

WebSpontaneous combustion of phosphine. Phosphine is a highly flammable gas, which easily can be ignited. In air it does not self-ignite, but in chlorine gas it does self-ignite, giving an … WebJul 1, 1995 · In previous articles, phosphine combustion products were shown to catalyze H + OH recombination in equilibrium relaxation experiments. In this work, calculations of heat release and specific impulse are reported for combustion products expanding at supersonic velocities in a nozzle. The calculations use a reaction set with 11 phosphorus ... earth evolution timeline

One can note that Na 3 P as the reduction product releases flammable and toxic phosphine, PH 3, upon hydrolysis. This will inevitably restrict and limit its practical use, similar ... Organophosphorus chemistry Phosphine is a precursor to many organophosphorus compounds. It reacts with formaldehyde in the presence of hydrogen chloride to give tetrakis(hydroxymethyl)phosphonium chloride, which is used in textiles. The hydrophosphination of alkenes is versatile route to a variety of … See more 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 See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in … See more Phosphine may be prepared in a variety of ways. Industrially it can be made by the reaction of white phosphorus with sodium or potassium hydroxide, producing potassium or sodium hypophosphite as a by-product. 3 KOH + P4 + 3 H2O … See more • Diphosphane, H2P−PH2, simplified to P2H4 • Diphosphene, HP=PH See more PH3 is a trigonal pyramidal molecule with C3v molecular symmetry.
