The macrokinetics and products of self-propagating high-temperature synthesis (SHS) in the solid-phase triphenylphosphine-chloramine system were studied by TGA-DTA, XRD, and 31P NMR techniques. The temperature of SHS ignition (59 deg C), the velocity of reaction waves (1.6-5.0 nm s-1), and the maximum temperature (155-239 deg 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.
