Definitions

  • the invention relates to fluorine-containing alkylsulfobetaines, a process for their preparation and their use.
  • R f is a perfluoroalkyl radical with 3 to 16 carbon atoms
  • R 1 and R 2 which may be the same or different, alkyl radicals or hydroxyalkyl radicals with 1 to 4 carbon atoms
  • a is zero or 1
  • R 1 and R 2 identical or different, in these compounds are preferably an alkyl radical or a hydroxyalkyl radical having 1 to 2 carbon atoms and a is 1.
  • the present invention also encompasses a process for the preparation of the fluorine-containing alkylsulfobetaines defined above, which is characterized in that a fluorine-containing amine of the general formula wherein R f , R 1 , R 2 , a and b have the meaning defined above, with a sulton of the general formula wherein c has the meaning defined above, in an organic solvent to react.
  • the fluorinated amines used as the starting compound are known; they can be prepared, for example, by methods such as those described in US Pat. No. 3,257,407, US Pat. No. 3,535,381, DE-AS 16 68 794, and DE-OS 17 68 939 or DE-OS 21 41 542 are described.
  • Propane sultone or butane sultone are used as sulfoalkylating agents.
  • the reaction is carried out in an organic solvent which must be inert to the reactants. Suitable solvents for the reaction are, for example, methanol, ethanol, butyl glycol, butyl diglycol or acetone.
  • the appropriate reaction temperature is in the range from 50 to 100 ° C., the reaction takes place under essentially pressure-free conditions. At these temperatures, the sulfoalkylation lasts between 1 and 10 hours. The sultons should not be used beyond the stoichiometrically required proportion, since they are toxic.
  • the fluorinated alkylsulfobetaines can be obtained in solid form by distilling off the solvent. However, the solution of the products in the organic solvent obtained from the sulfoalkylation can also be used for many applications.
  • the fluorine-containing alkylsulfobetaines according to the invention of the formula defined above are distinguished by a considerable reduction in the surface tension (water / air) and in particular by a high surface-active activity at the interface between water and immiscible organic liquids, in particular hydrocarbons.
  • the fluorinated alkyl sulfatobetaines known from DE-OS 2749329 result in such a lowering of the interfacial tension water / immiscible organic liquid at the low application concentrations which occur in practice only when a synergistic second component, such as a fluorinated alkylammonium monoalkyl sulfate, is described in DE -OS 2749330, is present.
  • the fluorinated alkylsulfobetaines according to the invention are absolutely compatible with cationic, nonionic and anionic surfactants.
  • the fluorine-containing alkylsulfobetaines according to the invention are also far superior in their hydrolysis stability to the known fluorine-containing alkylsulfatobetaines.
  • the fluorine-containing alkylsulfobetaines according to the invention are suitable because of their good compatibility speed with other non-ionic surfactants, such as oxalkylated phenols, as post-stabilizers in the production of polytetrafluoroethylene dispersions and dispersions of other fluoropolymers or copolymers, also as leveling agents for waxes, as cleaning enhancers in chemical cleaning and in particular because of their good surface-active activity as Mixture components in fire extinguishing agents.
  • non-ionic surfactants such as oxalkylated phenols
  • post-stabilizers in the production of polytetrafluoroethylene dispersions and dispersions of other fluoropolymers or copolymers, also as leveling agents for waxes, as cleaning enhancers in chemical cleaning and in particular because of their good surface-active activity as Mixture components in fire extinguishing agents.
  • Example 2 The procedure is as in Example 1, but acetone is used instead of the ethanol. After filtration and drying, 298 g, corresponding to a yield of 97% of theory, of the compound of Example 1 are obtained. The determination of the amine number shows that the product still contains 0.5% free amine.
  • Example 2 The procedure is as in Example 1, but butyl glycol is used as the solvent instead of ethanol. 1,715 g of the fluorine-containing amine referred to in Example 1 and 2,100 g of butyl glycol are heated to 60 ° C. and 425 g of propanesultone are added dropwise at this temperature. The mixture is then stirred at 80 ° C for 3 hours. To obtain a 40% solution, 1000 g of water are added. The amine number determination shows that 0.4% free amine is still present.
  • Example 3 64 g (N-1,1,2-trihydroperfluoroalkenyl-2) -N-dimethylamine (in which the R, radical has the meaning given in Example 1), 18.2 g propane sultone and 83 ml Butylglycol implemented.
  • the sulfobetaine of the formula obtained contains 1.0% free amine according to the amine number.
  • the constitution of the sulfobetaines obtained was confirmed by their 1 H-NMR spectra and IR spectra.
