ABSTRACT:
A process for preparing tri- and tetra-phosphonitrilic chlorides in a shortened period of time in high yields by reacting ammonium chloride with phosphorus pentachloride in an organic solvent inert to chlorine in the presence of at least one catalyst selected from metal oxides of Groups II-A, II-B, III-A, IV-A, IV-B and VIII of the Periodic Table, metal sulfides, metal salts of fatty acids, metal complexes, organometallic compounds and metal peroxides of Groups II-A and II-B of the Periodic Table, metal hydroxides of Groups III-A and VIII of the Periodic Table, and magnesium hydroxide. Phosphorus pentachloride may also be produced simultaneously with the reaction by reacting phosphorus trichloride employed instead of phosphorus pentachloride with chlorine gas supplied into the reaction system, or by previously reacting phosphorus employed instead of phosphorus pentachloride with chlorine gas supplied into the reaction system to produce phosphorus trichloride and then reacting phosphorus trichloride with chlorine gas in the same manner as in the case using phosphorus trichloride as the starting material.
