摘要: Colorless, or but very faintly tinted N-(dichlorophosphoryl)trichlorophosphazene [P.sub.2 NOCl.sub.5 ] is prepared by reacting phosphorus pentachloride with ammonium chloride in the presence of POCl.sub.3, and then treating the resulting medium of reaction, containing P.sub.3 NCl.sub.12, with SO.sub.2, and wherein the temperature of the medium of reaction is maintained at a value of at most about 30.degree. C.
