Definitions

  • the present invention relates to new additive mixtures, processes for their production and their use for turbine oils.
  • Turbines such as steam turbines, gas turbines and water turbines are typically used to convert kinetic energy into electricity. Effective turbine oils are essential as lubricants for trouble-free operation. The key here is the ability to provide reliable lubrication over a longer period of time at high operating temperatures.
  • a suitable turbine oil for general applications has a number of desirable properties to accommodate various operating conditions across several types of modern industrial turbines. These properties include, for example, a high viscosity index (VI), high oxidation stability (and associated long service life), low varnish/sludge formation, good water separation properties, improved rust and/or corrosion resistance and improved air release and foam properties.
  • VIP viscosity index
  • oxidation stability and associated long service life
  • varnish/sludge formation good water separation properties
  • improved rust and/or corrosion resistance improved air release and foam properties.
  • additives for turbine oils which contain nonyl or dinonyl or styrene-substituted N- ⁇ -naphthyl-N-phenylamines and nonyl or dinonyl or styrene-substituted diphenylamines as antioxidants.
  • octyl-substituted N- ⁇ -naphthyl-N-phenylamines are increasingly being used, individually or in combination with various additives, such as US-A 5726135 , whereby these have the disadvantage that they are poorly soluble in a mixture with other additives and a larger amount of a solubilizer is required to obtain a liquid additive mixture.
  • turbine oils are known whose oil contains one or more antioxidants from the group of N- ⁇ -naphthyl-N-phenylamine and diphenylamine as well as sulfur-containing additives as additional components.
  • Sulfur-containing compounds are known to be able to improve oxidation stability in lubricants, as evidenced by results in the Rotation Pressure Vessel Oxidation Test (RPVOT, ASTM D 2272) and the oxidation-corrosion test according to ASTM D 4636. Examples can also be found in WO2019/183187 .
  • many sulfur-containing compounds tend to form sludge, which has a negative impact the results of other oxidation tests such as B. the dry TOST according to ASTM D 7873.
  • the object of the present invention is to provide an improved additive mixture which can be used as a turbine oil in particular in combination with a base oil, this turbine oil meeting both the requirements of the oxidation test according to ASTM D 7873 and passing the corrosion and oxidation test according to ASTM D 4636 .

It is particularly preferred that the mixture of compounds of the formula (II) consists of 90% by weight of compounds in which R 2 and R 3 are a C 4 or C 8 alkyl radical.

  • the aforementioned benzotriazoles are preferred as mixtures of 1H-benzotriazole and 2H-benzotriazole in a ratio of 60 - 70 % by weight (1H) to 40 - 30% by weight (2H).

  • the additive mixture contains at least one corrosion inhibitor, particularly preferably a carboxamide (f).
  • carboxamides preferably amides of carboxylic acids with 4-50 carbon atoms, such as N-oleylsarcosine or succinic acid amides, can be used.
