WebJan 1, 1984 · Abstract; The flammability limit of pure phosphine in air at 1037 ± 14 mb total pressure with 0.39% v/v water vapour was found to be 2.1% v/v phosphine at 10°C, falling to 1.85% v/v at 50°C. The limit value increased slightly with increasing water vapour concentration. The data is discussed in terms of the mechanism and kinetics of oxidation ... WebPhosphine 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 phosphines.
