  Titanium butoxide tris(5H-octafluoropentanoate), Ti(OnC4H9)[OCO(CF2)4H]3, titanium butoxide tris(7H-undecafluoroheptanoate), Ti(OnC4H9)[OCO(CF2)6H]3, titanium butoxide tris(9H-hexadecafluorononanoate), Ti(OnC4H9)[OCO(CF2)8H]3, and titanium butoxide tris(perfluorooctanoate), Ti(OnC4H9)[OCO(CF2)6CF3]3, were prepared by the reaction of titanium butoxide trichloride with sodium fluoro-substituted acylates in 1,1,2-trichloro-1,2,2-trifluoroethane. These compounds were characterized on the basis of elemental analysis as well as their IR, 1H NMR, 13C NMR, and 19F NMR spectra. In the compounds produced, a Ti–OCO bond was stable in water, although a Ti–OR bond was only moderately stable in water. A surface modification against calcium carbonate was attempted by using these products. From measurements of the contact angles θ(°) of water and toluene against a modified calcium carbonate surface, titanium butoxide tris(perfluorooctanoate) was found to be an effective substance for a new-type coupling agent, which increases the affinity between organofluoro polymers and some inorganic substances.

  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.
