PROBLEM TO BE SOLVED: To provide a method for producing fluorine-containing carboxylic acid or fluorine-containing carboxylate.
SOLUTION: The fluorine-containing carboxylic acid [when M in formula (II) is H] or the fluorine-containing carboxylate [when M in formula (II) is a metal], represented by general formula (II) Rf-COOM [wherein Rf is a 1-20C fluoroalkyl; and M is H or the metal], is produced by reacting a fluorine-containing alkene of general formula (I) Rf-CF=CH-R [wherein Rf is the same as represented in formula (II); and R is a (substituted) alkyl] with an oxidizer.

physicochemically adsorbed films and tribochemical reaction films were produced on Ti alloy tribopair surfaces during sliding when lubricated with the TPP ILs. The formation of physicochemically adsorbed films between the TPP ILs and the friction surfaces were mainly responsible for the superior tribological properties compared to the reference samples. By comparing the tribological properties of TPP ILs with
系统研究了各种四烷基鏻全氟磺酸盐离子液体(TPP ILs、C6F13SO3P4444、C8F17SO3P4444 和 C8F17SO3P8888)对 Ti-6Al-4V 摩擦对的润滑,并与基于 BF4− 或 PF6− 和 TFSI− 阴离子的常规 ILs 润滑剂进行了比较。结果表明,TPP ILs 在 Ti-6Al-4V 上具有优于现有 IL 润滑剂的润滑性能。润滑机理分析表明,当使用 TPP ILs 润滑时,Ti 合金 tribopair 表面在滑动过程中会产生物理化学吸附膜和摩擦化学反应膜。与参考样品相比,TPP ILs 和摩擦表面之间物理化学吸附膜的形成是优越的摩擦学性能的主要原因。通过比较 TPP ILs 与全氟磺酸四丁基铵 IL C8F17SO3N4444 和羧酸四丁基膦 IL C8F15O2P4444 的摩擦学特性,发现全氟磺酸盐 ILs 的化学结构对润滑能力有显着影响。磺酸盐基团和含

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.

An aqueous solution containing a fluorine-containing emulsifier in a low concentration of at least 1 ppm by mass and at most 1% by mass (e.g., coagulation waste water after an emulsion polymerization of a fluoropolymer and/or an aqueous solution obtained by washing with an aqueous solution a waste gas from a drying process and/or a heat treating process of the fluoropolymer) is subjected to vacuum concentration under a pressure of at most 100 kPa and a temperature of the aqueous solution of at most 100°C by means of a heating tube surface evaporation type concentrator equipped with a heat pump or the like, and the fluorine-containing emulsifier is recovered from a highly concentrated aqueous solution containing the fluorine-containing emulsifier in a higher concentration of at least 5% by mass. According to the present method, the fluorine-containing emulsifier can be recovered with a high yield from a low-concentration liquid such as coagulation waste water of a fluoropolymer.
