    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.

    摘要: N-(Dichlorophosphoryl)trichlorophosphazene [P.sub.2 NOCl.sub.2 ], essentially devoid of oligomeric impurities, is improvedly and reproducibly prepared by reacting phosphorus pentachloride with ammonium chloride, advantageously stoichiometrically, wherein more than 50% by weight of the ammonium chloride is of a particle size less than 0.16 mm.
