  本发明公开了一种含氟羧酸的生产工艺，该方法是以含氟烯烃为原料，通过氧化反应后得到含氟羧酸盐，再将含氟羧酸盐与酰氯化试剂反应得到相应的含氟酰氯和含氟酸酐的混合物，再将含氟酰氯和含氟酸酐的混合物水解干燥后制备高纯度含氟羧酸。本发明方法适用于含氟烯烃（单烯烃、二烯烃、环烯烃等）氧化法制备含氟羧酸的后处理，代替传统的强酸酸化和乙醚连续萃取工艺，更为简便适用；本发明制备的含氟羧酸纯度可达98%以上。

  A method for adsorbing and recovering a fluorine-containing emulsifier at a high recovery from coagulation waste water of a fluoropolymer, is presented. An inorganic acid is added to coagulation waste water of a fluoropolymer containing a fluorine-containing emulsifier, to adjust the pH of the waste water to a level of at least 1 and less than 6, then a metal chloride having a solubility of at least 5 mass% in water at 25°C, or a hydrate of the metal chloride, is added to the waste water, to coagulate and remove a solid content and/or a substance convertible to a solid content, contained in the waste water, and then the waste water is contacted to a weakly basic anion exchange resin.
