A Fluorination Method for Phosphonitrilic Chloride Trimer and Its Derivatives

The present invention relates to a fluorination method for phosphonitrilic chloride trimer and its derivatives including using phosphonitrilic chloride or partially substituted phosphonitrilic chloride trimer as raw material to fluorinate with fluoridating agent in an ionic liquid to replace the chlorine in chloro-cyclotiphosphazene molecule. The present invention uses non-volatile and pollution free ionic liquids as solvent, and just controls a distillation temperature to get a hexafluorocyclotriphosphazene or derivatives thereof with high-purity. It overcomes the shortcoming of the average solvent system that the solvent forms azeotrope with products. The post-process is simple. The production rate is high, and the ionic liquid can be recycled. The present invention produces products with high purity.
