Definitions

  • the present invention relates to hydraulic fluids, in particular brake fluids for motor vehicles, with improved corrosion protection, which contain 0.005 to 0.5% by weight of one or 10 more heterocyclic compounds of the general formula I,
  • R in each case independently of any other radicals R, denotes a hydrogen atom or a radical R 1 ,
  • Ri each independently of other R 1 radicals present, alkyl, aryl, aralkyl, halogen, haloalkyl, optionally alkyl, aryl or aralkyl-substituted amino, a heterocyclic radical, cyano, carboxyl, alkoxycarbonyl, hydroxyl or alkoxyl, the abovementioned organic radicals for Ri each 1 to
  • n 0, 1 or 2.
  • Hydraulic fluids and in particular brake fluids 40 for motor vehicles are subject to very high requirements with regard to their chemical and physical properties.
  • modern brake fluids are said to have high dry boiling points (Rüc boiling points, dry [Equilibrium reflux boiling point, "ERBP”]) and high wet boiling points (reflux boiling points, moist ["wet ERBP”]), but on the other hand also have a viscosity which changes only slightly within a wide temperature range.
  • the hydraulic fluids and brake fluids for Kra t vehicles known in the prior art are still in need of improvement in this regard.
  • the object was therefore to provide hydraulic liquids which meet the above-mentioned requirements for improved non-ferrous metal corrosion protection.
  • Alkyl groups for R 1 are preferably linear or branched C 1 -C 20 -, in particular C 1 -C 8 -alkyl groups, for example methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl , tert.-butyl, n-pentyl, sec.-pentyl, iso-pentyl, neo-pentyl, n-hexyl, n-heptyl, n-octyl, 2-ethylhexyl, n-nonyl, iso-nonyl, n-decyl , iso-decyl, n-ündecyl, n-dodecyl, n-tridecyl, iso-tridecyl, n-tetradecyl, n-hexadecyl,
  • R 1 can also be C 5 -C 8 -co-alkyl, such as cyclopentyl or cyclohexyl.
  • R 1 can also mean unsaturated C 3 -C 20 -alkyl radicals, ie -alkenyl radicals, for example allyl, oleyl, linolyl or linolenyl.
  • Aryl groups for R i are preferably C 6 - to C 20 -aryl groups, which can be substituted by C 1 -C 4 -alkyl radicals, for example phenyl, naphthyl, o-, m- or p-tolyl, o-, - or p-ethylphenyl or xylyl.
  • Aralkyl groups for R 1 preferably have 7 to 20 C atoms.
  • these are corresponding alkyl radicals which carry an optionally alkyl-substituted phenyl substituent. Examples include benzyl, 2-phenylethyl, 3-phenylpropyl, 4-phenylbutyl, o-, m- or p-methylbenzyl or o-, m- or p-ethylbenzyl.
  • Halogen atoms for R 1 are in particular fluorine, chlorine, bromine and iodine.
  • Haloalkyl groups for R 1 are preferably mono-, di- or tri-haloalkyl groups with 1 to 20, in particular 1 to 8, carbon atoms.
  • Mono-, di- and trihalomethyl groups such as fluoromethyl, chloromethyl, bromomethyl, difluoromethyl, dichloromethyl, dibroromethyl, fluorochloromethyl, chlorobromomethyl, fluorobromomethyl, trifluoroethyl, trichloroethyl, tribromomethyl, fluorodichloromethyl, difluorochloromethyl are particularly preferred. Chlorodibromomethyl, dichlorobromomethyl, difluorobromomethyl or fluorochlorobromomethyl.
  • alkyl, aryl or aralkyl-substituted amino for RI denotes in particular the groups -NH, -NHR 2 and -N (R 2 ), where R 2 independently of one another has the meanings given above for alkyl, aryl or aralkyl in the radical R 1 , Examples of this include, in addition to unsubstituted amino, methylamino, dirnethylamino, ethyl ino, diethylamino, butylamino, dibutylamino, phenylamino or benzylamino.
