A process for phosphorus pentafluoride production by which high-purity phosphorus pentafluoride can be produced by a simple and economical procedure without the need of a large-scale purification apparatus or high-pressure apparatus and without generating a large amount of a by-product gas requiring a special discharge-gas treatment. The process for phosphorus pentafluoride production is characterized by introducing hydrogen fluoride and a hexafluorophosphate (MPF6) into a vessel and reacting them according to the reaction shown by the scheme (1) to yield phosphorus pentafluoride. MPF6 + uHF .fwdarw. PF5 + MF r(HF) (Scheme 1) In the scheme, M is at least any one of Li, Na, K, Rb, Cs, NH4, and Ag; 0<=r<=u; and the HF is used in an amount not smaller than the stoichiometric amount.
La présente invention concerne un procédé simple et économique de production de pentafluorure phosphoreux hautement pur sans avoir besoin d'appareil de purification à grande échelle ni d'appareil haute pression, et sans rejeter de grandes quantités de gaz nécessitant de traitement spécial. Le procédé est caractérisé par l'introduction de fluorure d'hydrogène et d'hexafluorophosphate (MPF6) dans une cuve et leur mise en réaction selon le schéma (1) suivant : MPF6 + uHF .fwdarw. PF5 + MF r(HF) donnant un pentafluorure phosphoreux. Dans ce schéma, M est l'un au moins de Li, Na, K, Rb, Cs, NH4, et Ag; 0<=r<=u; et le HF est utilisé en une quantité non inférieure à la quantité stAEchiométrique.
