| description | The invention belongs to the field of phosphorus halides, and particularly relates to a preparation method of phosphorus pentafluoride. The preparation method of phosphorus pentafluoride comprises the following steps: (1) mixing a first mixed acid containing fluorosulfonic acid and anhydrous hydrogen fluoride with a hexafluorophosphoric acid solution, reacting and dehydrating to obtain a second mixed acid; the second mixed acid contains fluorosulfonic acid, sulfuric acid, hexafluorophosphoric acid and hydrogen fluoride; and (2) pyrolyzing the second mixed acid to obtain mixed gas containing phosphorus pentafluoride. According to the preparation method of phosphorus pentafluoride provided by the invention, the first mixed acid containing fluorosulfonic acid and anhydrous hydrogen fluoride is used as a dehydration raw material, heat release in the mixed dehydration process is much milder than that under the condition that fuming sulfuric acid or sulfur trioxide is used as a raw material, and the temperature ris |
