| titleOfInvention | Preparation method of perfluorosulfonic acid resin solid |
| abstract | The invention discloses a preparation method of perfluorosulfonic acid resin solid, which comprises the following steps: a. dispersing perfluorosulfonic acid resin in a solvent to obtain perfluorosulfonic acid resin dispersion liquid; b. adding the perfluorosulfonic acid resin dispersion liquid obtained in the step a into an organic precipitator, precipitating a precipitate, and filtering to obtain a solid product, wherein the organic precipitator is selected from at least one of a first precipitator, a second precipitator and a third precipitator, and the solvent in the step a is mutually soluble with the precipitator; c. and c, drying the solid product obtained in the step b to obtain a perfluorosulfonic acid resin solid. The method can obtain pure perfluorosulfonic acid resin solid, can improve the product purity in the production process, reduces sewage generated by the fluorine industry, and improves the stability of batches. |
