| titleOfInvention | Preparation method of fluorine-containing sulfoacid |
| abstract | The invention provides a preparation method of fluorine-containing sulfoacid. The preparation method comprises the following steps of: in parts by weight, mixing 14-27 parts of sodium hydrogensulfite, 15-30 parts of water and 6.6-13 parts of catalyst; adding 13.5-26 parts of fluorine-containing olefin and 2-8 parts of benzoyl peroxide for reaction at the temperature of 60-150 DEG C, wherein the reaction pressure is 0.5-2 Mpa, and the reaction time is 1-5 hours; and cooling after the reaction, filtering, dewatering, rectifying at reduced pressure, and then obtaining the target product. In the preparation method, an addiction reaction is adopted, and materials can be continuously fed; compared with the electrolytic process, the cost is reduced by above 30%, and the reaction is stable in the whole process; the preparation method has the advantages of good safety, less byproducts and high yield, is simple to operate and environment friendly; and by using the preparation method, the fluorine-containing sulfoacid which has the purity of more than 98% can be obtained. |
