| titleOfInvention | Anionic fluorocarbon surfactant and preparation method thereof |
| abstract | The invention relates to an anionic fluorocarbon surfactant and a preparation method thereof. The structural formula of the anionic fluorocarbon surfactant is as follows: CF3CF2CF2C(CF3)2CH2C6H4PO(OM)2, wherein M is equal to Li, Na, K or NH4. The preparation method comprises the following steps: (1) reacting hexafluoropropylene dimer and p-Bromobenzyl bromide to generate a fluorine-containing intermediate compound 1; (2) coupling the fluorine-containing intermediate compound 1 with dimethyl phosphite to obtain a fluorine-containing intermediate compound 2; (3) hydrolyzing the fluorine-containing intermediate compound 2 to generate a fluorine-containing organic acid 3; and (4) neutralizing the fluorine-containing organic acid 3 with alkali to obtain a product. The method has the advantages of being, simple, low in cost and good in repeatability, and raw materials can be easily obtained. The surface tension performance of the product is good. |
