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 at high operating temperatures over a longer period of time.
- a suitable general purpose turbine oil exhibits a number of desirable properties to address various operating conditions in 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 release properties, improved rust and/or corrosion resistance and improved air release and foaming properties.
- VIP viscosity index
- oxidation stability and associated long service life
- low varnish/sludge formation good water release properties
- improved rust and/or corrosion resistance improved air release and foaming properties.
- additives for turbine oils which contain nonyl- or dinonyl or styrene-substituted Na-naphthyl-N-phenylamine and nonyl- or dinonyl or styrene-substituted diphenylamine as antioxidants.
- octyl-Na-naphthyl-N-phenylamines are increasingly used, individually or in combination with various additives, such as US-A 5726135 , these having 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-phenylamines and diphenylamines as well as sulfur-containing additives as further components.
- Sulfur-containing compounds are known to improve oxidation stability in lubricants, as evidenced by results from the Rotation Pressure Vessel Oxidation Test (RPVOT, ASTM D 7727) and ASTM D 4636 Oxidation Corrosion Test. Examples can also be found in WO2019/183187 .
- many sulphur-containing compounds tend to form sludge, which has a negative impact the results of other oxidation tests such as e.g. B. the dry TOST according to ASTM D 7873 affects.
- 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, with this turbine oil meeting the requirements of the oxidation test according to ASTM D 7873 and the corrosion and oxidation test according to ASTM D 4636 .
- an additive mixture containing one or more C 10 -C 14 - alkyl-substituted N- ⁇ -naphthyl-N-phenylamines (APAN), alkyl-substituted diphenylamines (DPA), at least a sulfur-containing compound from the group of C 8 -C 12 -alkyl-substituted-2,5-dimercapto-1,3,4-thiadiazoles and a benzotriazole derivative.
- APAN alkyl-substituted N- ⁇ -naphthyl-N-phenylamines
- DPA alkyl-substituted diphenylamines
- sulfur-containing compound from the group of C 8 -C 12 -alkyl-substituted-2,5-dimercapto-1,3,4-thiadiazoles and a benzotriazole derivative.
- carboxylic acid amides preferably amides of carboxylic acids having 4-50 carbon atoms, such as, for example, N-oleylsarcosine or succinic acid amides, can be used as corrosion inhibitors (f) .
- the additive mixture contains at least one thiophosphate (g).
- thiophosphate (g) For the purposes of the invention, neutral, covalently bonded thiophosphates and also ionic thiophosphates such as amine-neutralized thiophosphoric acid derivatives can be used as thiophosphate (g) .
- the additive mixture contains demulsifiers selected from the group of polyglycols and/or defoamers selected from the group of polyacrylates.
- the polyglycols preferred as demulsifiers are preferably block copolymers of polypropylene glycol and polyethylene glycol.
- the polyacrylates preferred as defoamers are preferably homo- or copolymers of derivatives of acrylic acid, for example methacrylic acid.
- a non-polar olefin is preferably used as the comonomer.
- Dispersants, detergents or flowability-improving additives can also be used as further components of the additive mixture.
- the present invention also relates to a process for preparing the additive mixture according to the invention, according to which components (a) to (d) and optionally (e) to (g) are mixed in any order at temperatures from 20 to 100° C., preferably 60-80° C to be mixed. These are preferably stirred until a homogeneous liquid is obtained.
- the subject matter of the present invention is also a turbine oil containing the additive mixture according to the invention, preferably at 0.1-2% by weight, in a base oil.
- API American Petroleum Institute
- the present invention also relates to a process for producing the turbine oil according to the invention, according to which the additive mixture according to the invention with components (a) to (d) and optionally (e) to (g) is heated at temperatures between 20 and 100° C., preferably 40-80 °C are stirred into a base oil.
- the subject matter of the present invention is also the use of the additive mixture according to the invention, preferably in a base oil, as a turbine oil.
- the compounds (a) to (f) specified in Table 1 were mixed together in the amounts (% by weight) specified there at 70° C. until a homogeneous solution was formed.
- the mixtures of Examples B to D are liquid.
- the mixture from example A (comparative example according to EP-A 1730101 ) is solid and therefore cannot be used in the oil without first melting it.
- Turbine oils fail a test according to ASTM D 4636 if the weight change of one of the metals (Al, Fe, Cu, Mg or Cd) is greater than 0.25 mg/cm 2 .
- a test according to ASTM D 7873 is passed if, after 1000 h, the RPVOT time is at least 25% of the original RPVOT time and the sludge is below 100 mg/kg after 1000 h.
- the following standard tests were carried out: The Dry TOST according to ASTM D 7873, as a standard test method for determining the oxidation stability and the formation of insoluble substances of turbine oils at 120°C without inclusion of water (dry TOST method) and the oxidation test according to ASTM D 4636.
