Abstract: | The macrokinetics and products of self-propagating high-temperture synthesis (SHS) in the solid-phase triphenylphosphine—chloramine
system were studied by TGA-DTA, XRD, and31P NMR techniques. The temperature of SHS ignition (59°C), the velocity of reaction waves (1.6–5.0 mm s−1), and the maximum temperature (155–239°C) in the SHS wave were measured. The chemical composition of the product obtained
was established: phosphine oxide, triphenyl-N-(phenylsulfoyl)-phosphinimine, benzenesulfonamide, NaCl, and water. The scheme of chemical reactions occurring during SHS
was proposed.
