| titleOfInvention | A kind of preparation method of hexafluorophosphate |
| abstract | The invention discloses a preparation method of hexafluorophosphate, belonging to the technical field of chemical synthesis; the preparation method of hexafluorophosphate provided by the invention comprises the following steps: (1) dissolving hydrogen fluoride salt in carbonate solvent , and add phosphorus pentachloride in batches under a reduced pressure environment, and stir the reaction, and the temperature of the stirring reaction is 30-60 ° C; (2) after the stirring reaction is completed, filter, the obtained filtrate is concentrated, cooled, and crystallized, and then Filtration to obtain hexafluorophosphate crystals; the technical solution provided by the present invention is for the first time used in carbonate solvents, by reacting solid hydrogen fluoride salt and phosphorus pentachloride under reduced pressure to prepare hexafluorophosphate; using the technology of the present invention Scheme In the process of preparing hexafluorophosphate, no highly toxic gas is used at the source, and no highly corrosive raw materials are used, and at the same time, the by-products of the present invention are less and the treatment is simple; on the whole, the preparation method provided by the present invention is It is safe, environmentally friendly, and the yield and purity of the obtained product are high. |
