Definitions

  • EP-A 454 490 describes ternary mixtures Isopropanol, water and a perfluorocarbon with one Boiling point of 30 to 70 ° C known as Serve cleaning solutions.
  • Preferred compounds of the above formula are in which x is 1 to 3, w is 4 to 6 and y is 7 to 13.
  • Particularly preferred compounds are 3,4-dihydroperfluoro (2-methylpentane), 3,4,4-trihydroperfluoro (2-methylpentane), Mixtures of these two compounds by weight ratio from 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 mixture of 6.76 parts by weight of isopropanol is added and 1 part by weight of water 20% by weight, based on this Mixture, to one of the compounds mentioned, so obtained a flash point (according to DIN 51 758) of over 50 ° C.
  • a flash point (according to DIN 51 758) of over 50 ° C.
  • 1H-perfluorohexane already causes an addition of 10% by weight a flash point of 50 to 52 ° C and with a mixture about 90% by weight 3,4-dihydro-perfluoro (2-methyl-pentane) and 10 wt .-% 3,4,4-trihydro-perfluoro (2-methyl-pentane) a Flash point above 55 ° C.
  • the invention therefore relates in particular to mixtures of predominantly isopropanol and smaller, approximately equal amounts Water and fluorinated compound.
  • Preferred mixtures contain 70 to 80% by weight isopropanol, 10 to 12% by weight water and 9 to 18% by weight fluorinated compound.
  • a preferred mixture consists of, for example 72.6% by weight of isopropanol, 10.7% by weight of water and 16.7% by weight Trifluoroethyl tetrafluoroethyl ether.
  • Particularly preferred mixtures consist of 79.2% by weight Isopropanol, 11.7% by weight water and 9.1% by weight fluorinated Hydrocarbon.
  • the fluorinated hydrocarbons are known Links. You can, for example, by hydrogenation of the corresponding olefins [V.F. Snegirev et al., Izv. Akad. Nauk SSSR, Ser. Khim. (12), 2775 to 2781 (1983)].
  • the fluorinated ether is obtained one, for example, by the addition of alcohols fluorinated olefins (Houben-Weyl, 'Methods of Organic Chemie ', 4th edition, volume V / 3 (1962), halogen compounds, Page 280).
