ABSTRACT:
A process for the preparation of phosphonitrile chloride oligomer, particularly, phosphonitrile chloride trimer at a high yield while suppressing the by-production of phosphonitrile chloride tetramer by reacting phosphorus pentachloride and ammonium chloride in an inert organic solvent under the presence of a polyvalent metal compound catalyst, wherein a catalytic amount of a compound selected from the group consisting of pyridine and alkyl-substituted pyridine derivatives capable of forming chloropyridinium salts in reaction with phosphorus pentachloride is present in the reaction system.
