Definitions

  • Particularly preferred compounds are 3,4-dihydro-perfluoro- (2-methyl-pentane), 3,4,4-trihydro-perfluoro- (2-methyl-pentane), mixtures of these two compounds in a weight ratio of about 95: 5 to about 5:95, preferably 90:10 to 10:90, 2,2,2-trifluoroethyl-1,1,2,2-tetrafluoroethyl ether and especially 1H-perfluorohexane.
  • a flash point (according to DIN 51 758) of over 50 ° C.
  • 1H-perfluorohexane an addition of 10% by weight already has a flash point of 50 to 52 ° C. and in the case of a mixture of about 90% by weight of 3,4-dihydro-perfluoro- (2-methylpentane) and 10 Wt .-% 3,4,4-trihydro-perfluoro (2-methyl-pentane) a flash point of over 55 ° C.
  • the mixtures mentioned are single-phase at 0 ° C. and are not yet saturated with the fluorinated compound. These can therefore be mixed with water / isopropanol within a wide range.
  • the invention therefore relates in particular to mixtures of predominantly isopropanol and smaller, approximately equal amounts of water and fluorinated compound.
  • Preferred mixtures contain from about 70 to about 80 weight percent isopropanol, about 10 to about 12 weight percent water, and about 9 to about 18 weight percent fluorinated compound.
  • a preferred mixture consists, for example, of 72.6% by weight of isopropanol, 10.7% by weight of water and 16.7% by weight of trifluoroethyl tetrafluoroethyl ether.
  • Particularly preferred mixtures consist of 79.2% by weight of isopropanol, 11.7% by weight of water and 9.1% by weight of fluorinated hydrocarbon.
  • the fluorinated hydrocarbons are known compounds. They can be prepared, for example, by hydrogenating the corresponding olefins [V.F. Snegirev et al., Izv. Akad. Nauk SSSR, Ser. Khim. (12), 2775 to 2781 (1983)].
  • the fluorinated ethers are obtained, for example, by adding alcohols to fluorinated olefins (Houben-Weyl, 'Methods of Organic Chemistry', 4th edition, Volume V / 3 (1962), Halogentagen, page 280).
