Definitions

  • lubricants are particularly suitable for refrigeration machines, heat pumps and related systems such as air conditioning systems. They can also be used as compressor and hydraulic oils.
  • Lubricants for refrigerating machine oils still mainly consist of highly refined mineral oils, which are dewaxed to improve the flow properties in the cold beyond what is customary for lubricating oils.
  • Pour points customary for chillers are in a range from -50 ° C to -25 ° C, depending on viscosity, and the cold pour points according to DIN 51568 are in a range between -16 ° C and -38 ° C.
  • the temperature at which flocculation of paraffin crystals occurs - important for the proper functioning of the lubricant - is also reduced by the additional dewaxing.
  • the mineral oils suitable for the production of refrigerating machine oils are obtained according to the known methods by distilling crude oils with subsequent refining (Ullmanns Encyklopadie der Technische Chemie, 4th edition, volume 20, pages 484 ff.). Depending on the origin of the crude oil, so-called paraffin-based or naphthenic-based lubricating oils are obtained.
  • Paraffin-based lubricating oils mainly contain paraffinic molecules, naphthenic-based predominantly naphthenic or cycloparaffinic molecules.
  • naphthenic oils are preferred for the production of refrigeration oils.
  • Refrigeration oils based on mineral oils usually contain no additives. Although attempts have often been made to improve the properties of the oils with the aid of additives, the success has so far been poor (ASHRAE Guide and Data Book 1969, section 23, page 281).
  • alkylbenzenes used come from the known syntheses according to Friedel-Crafts by alkylation of benzene with alkyl chlorides or olefins (Ullmann, 4th edition, volume 14, pages 672 ff.).
  • ⁇ -olefins which are produced by ethylene oligomerization or by cracking paraffins according to different processes, serve as raw material for the production of polymer oils (Ullmann, 4th edition, volume 14, pages 664 ff.).
  • these d-olefins are polymerized and hydrogenated ("Synthetic Poly- ⁇ -olefin Lubricants Today and Tomorrow", M.Campen, DFKendrick, ADMarkin, and Ullmann, 4th Edition, Volume 20, pages 505 ff.) .
  • the invention has for its object to provide lubricating oils with increased lubricating properties with improved low-temperature behavior and improved thermal stability and low foaming tendency.
  • the substituted phosphite can be, for example, a trinonylphenyl phosphite, triphenyl phosphite, dodecyl diphenyl phosphite, dioctylphenyl phosphite, tridodecyl phosphite, didecylphenyl phosphite.
  • the phosphites of medium molecular size such as, for example, dodecyl diphenyl phosphite or triphenyl phosphite are preferably used.
  • organic phosphates examples include diphenyl cresyl phosphate and other alkyl, aryl or alkylaryl derivatives of cresyl phosphate.
  • Trialkylaryl phosphates such as, for example, triisopropylphenyl phosphate or tricresyl phosphate are preferably used.
  • a methyl silicone is preferred as the silicone. It only serves to reduce foaming.
  • a coil of 0.1 mm copper wire and an approximately 15 mm long steel wire - 1.6 DIN 177-D5-1 - were inserted into glasses prepared in this way, 0.3 to 0.4 g of lubricant were weighed in and in a special device under vacuum and freezing added about the same amount of Freon refrigerant. Before the latter step, all gases were removed from the weighed oil by means of a vacuum. With the addition of nitrogen, the glasses were welded after the addition of the refrigerant. The glasses were then heated to the test temperature in a drying cabinet for a predetermined period. The test temperature was 175 ° C or 200 ° C, the test duration between 336 and 1008 hours (2 to 6 weeks).
  • alkylbenzene / mineral oil mixture (ratio 1: 1) was used as the base oil, viscosity class ISO 32, the alkylbenzene containing straight-chain C 10 -C 12 alkyls and the mineral oil component consisting of highly refined naphthenic-based oil. 1% of an isopropylated triphenyl phosphate with an average isopropyl content of 1.5 moles per mole of triphenyl phosphate and 0.005% methyl silicone was added.
  • Base oil from alkylbenzene with branched alkyl groups made from the reaction of benzene with tetrapropylene), viscosity class ISO 32, with the addition of 1% triisopropylphenyl phosphate and 0.005% methyl silicone.
  • Base oil from alkylbenzene with straight-chain alkyl groups viscosity class ISO 68, with the addition of 1% triisopropylphenyl phosphate and 0.005% methyl silicone.
  • Base oil from a mixture of poly- ⁇ -olefins, viscosity class ISO 68, with the addition of 1% triisopropylphenyl phosphate and 0.005% methyl silicone.
  • Base oil made from highly refined naphthenic mineral oil, viscosity class ISO 46, with the addition of 1% triisopropylphenyl phosphate and 0.005% methyl silicone.
  • the examples show a clear qualitative improvement in the refrigerating machine oils of the lubricants according to the invention with regard to oxidation and heat stability compared to the comparative examples.
