  • brake fluids should have the following basic properties: high dry boiling point (reflux boiling point dry) and wet boiling point (reflux boiling point wet) and a viscosity that changes only slightly over a wide temperature range.
  • DOT-3 and DOT-4 brake fluid are summarized below:
  • a brake fluid should also have a number of other properties.
  • Hydraulic fluids in particular brake fluids based on boric acid esters of glycols and / or glycol monoalkyl ethers, are already known which contain, as further main components, glycol monoalkyl ethers, glycol dialkyl ethers, polyglycols and / or bis (glycol ether) formals (compare German patent specification 939 045, German interpretations 17 68 933 and 24 57 097, German Offenlegungsschriften 21 41 441, 22 57 546, 24 37 936, 24 38 038, 25 25 403, 25 32 228, 27 24 193 and 28 04 535).
  • the object of the invention is therefore to provide a hydraulic fluid, in particular a brake fluid, which not only fully meets the property profile according to the standards currently required, but also meets the above-mentioned expanded requirements.
  • the preparation of the boric acid esters according to component A) - a reaction product of orthoboric acid, diethylene glycol and an ethylene glycol monoalkyl ether of the formula I in a molar ratio of 1: 1: 1 - is carried out according to known procedures.
  • the reaction components mentioned are reacted in a reaction vessel equipped with a stirrer and, if appropriate, a reflux condenser at a temperature of about 50 to about 150 ° C., preferably about 110 to about 140 ° C., with the water of reaction formed being continuously removed.
  • the reaction can be carried out in the presence of an inert water azeotroping solvent such as benzene, toluene, xylene, ethylene benzene or the like.
  • the water of reaction can also be removed by carrying out the reaction under reduced pressure, for example in a water jet vacuum (7 to 20 mbar).
  • a water jet vacuum 7 to 20 mbar.
  • the solvent which may be used is removed from the reaction product by customary distillation and, if further purification should be necessary, this is expediently vacuum stripped at a temperature of 90 to 150.degree .

  • component D are those alkylamines of the formula III in which R 3 is propyl, butyl, hexyl, octyl or isononyl, and R 4 and R S are the same and are hydrogen or CH 2 CH 2 OH.
  • Component E) of the hydraulic fluid according to the invention consists of customary additives for fluids based on boric acid esters and glycol derivatives.
  • additives include stabilizers, for example pH stabilizers, and inhibitors, for example inhibitors of corrosion and oxidation (antioxidants).
  • the pH stabilizers are preferably used in an amount of 0.1 to 4% by weight, based on the weight of the entire liquid.
