On October 11, 2024, Tianci Materials obtained an invention patent titled "Preparation Method and Device for Phosphorus Pentafluoride" with the patent publication number of CN118515249B, which was filed on July 19, 2024.
This technology involves an efficient preparation method for phosphorus pentafluoride, with the following steps: Firstly, a hexafluorophosphoric acid solution undergoes a primary atomization process to form atomized hexafluorophosphoric acid. Subsequently, under conditions of 80-140°C, sulfuric acid solution is subjected to a gas-liquid contact reaction with the atomized hexafluorophosphoric acid, yielding phosphorus pentafluoride and residual reaction liquid.
The preparation method of this invention not only enables the production of high-purity phosphorus pentafluoride but also boasts advantages such as high reaction efficiency and simplicity in the process.
