ABSTRACT:
Essentially pure and colorless N-(dichlorophosphoryl)trichlorophosphazene [P.sub.2 NOCl.sub.5 ] is prepared/purified under relatively moderate conditions, by reacting phosphorous pentachloride with ammonium chloride, treating the resulting medium of reaction, containing P.sub.3 NCl.sub.12, with SO.sub.2, and thin film evaporating the medium of reaction, advantageously in two stages, to eliminate SO.sub.2, POCl.sub.3 and SOCl.sub.2 values therefrom.
