| titleOfInvention | Preparation method of anhydrous hydrogen fluoride |
| abstract | The invention belongs to the technical field of production of inorganic chemical products, and particularly relates to a preparation method of anhydrous hydrogen fluoride. The preparation method of the anhydrous hydrogen fluoride comprises the following steps: reacting hydrogen fluoride with concentrated sulfuric acid to obtain hydrogen fluoride salt; the hydrogen fluoride salt is a hydrogen fluoride salt of an alkali metal or an alkaline earth metal. The invention adopts the reaction of the hydrogen fluoride salt and the concentrated sulfuric acid to prepare the anhydrous hydrogen fluoride, realizes the single high-efficiency conversion of fluorine, improves the productivity of the device and reduces the energy consumption of the process. |
