<p>Phosphonitrile chloride may be prepared by the action of ammonium chloride on phosphorus pentachloride, in the presence if desired of an inert organic solvent, at a temperature of about 140 DEG C. Specified solvents are carbon tetra-chloride, tetrachlorethane, chlorobenzene and orthodichlorobenzene. The reaction may be represented as proceeding thus:- nPCl5 + nNH4Cl-->(PNCl2)n + 4nHCl. Phosphonitrile chloride may be treated with dry ammonia the reaction being carried out, if desired in the presence of an inert organic solvent (as above). There is obtained in the course of this reaction hydrogen-amine compounds such as (P3N3Cl5NH2)n and (P3N3Cl4(NH2)2)n or aminated compounds such as (PN(NH2)2)n in accordance with the reaction:- (PNCl2)n + 4nNH3-->(PN (NH2)2)n + 2nNH4Cl. Examples describe the preparation of phosphonitrile chloride by heating together phosphorus pentachloride and ammonium chloride or by refluxing them in the presence of an inert organic solvent (as above). The phosphonitrile chloride is then treated with ammonia by bubbling the dry gas through a solution of it in an inert organic solvent as by putting it into suspension in liquid ammonia at -45 DEG C.</p> |
