Definitions
- the present invention relates to a lubricant composition containing an antioxidant that inhibits the oxidative degradation of the composition.
- the invention further relates to a method for producing the
- Lubricant manufacturers are under constant pressure to improve their products to meet the needs of manufacturers and users.
- the chemical and thermal stability of the lubricants and the associated resistance to oxidation processes are to be constantly improved.
- a high level of resistance to oxidation processes is of great importance since these impair the physical and chemical properties of the lubricant and reduce its ability to protect the surfaces treated with it.
- oxidation processes can increase the acidity of the lubricant, which accelerates the wear and corrosion of metal surfaces. Oxidation processes can also lead to the formation of oxidation products that Affect lubricity.
- Oxidation processes can increase the viscosity of the oil and thereby undesirably influence the distribution of the lubricant on the surfaces.
- metal-containing particles can be separated in the lubricant. These particles can act as an oxidation catalyst and accelerate the breakdown of the lubricant. This is especially true at high temperatures, such as are common in engines.
- an oil-soluble antioxidant is often added to lubricants.
- amines such as e.g. Bis- (4- (1, 1, 3,3-tetramethylbutyl) phenyl) amine, styrenated phenylamine, sterically hindered phenols such as e.g. Thio-diethylene-bis (2- (2, -di-tert-butyl-4-hydroxyphenyl) propionate and / or combinations of two or three of the groups mentioned are used as antioxidants.
- GB-A-1 271 556 discloses a
- An antioxidant additive which is a mixture of (a) the reaction product of a boron compound with a long chain hydrocarbon carboxylic acid or an anhydride thereof with a primary or secondary amine and (b) a polycyclic phenolic compound.
- US-A-5 354 484 describes a lubricant additive that provides high temperature stability and contains a mixture of (i) an amine salt of a substituted phosphoric acid and (ii) an amine substituted hydrocarbon succinic acid compound.
- the additives mentioned above generally show satisfactory antioxidative properties. However, the amount to be used is usually quite high, which is disadvantageous for cost reasons. In addition, at higher concentrations there is a risk that the properties of the lubricant will be changed in an undesirable manner. In addition, the aforementioned additives generally have to be synthesized in complex processes.
- a lubricant composition is also known from DE112010000922 T5, which comprises a base lubricant consisting of a base oil and a thickener and an additive added to the base lubricant, the additive comprising at least one compound which consists of polyphenol compounds derived from plants and compounds formed by decomposing them is selected.
- Preferred polyphenol compounds are gallic acid, ellagic acid, chlorogenic acid, caffeinic acid, curcumin and quercetin.
- polyphenol compounds are natural products.
- the compounds mentioned show a rather low antioxidative effect.
- some of them are strongly colored (e.g. curcumin), which limits their possible uses. Presentation of the invention

- a lubricant composition which contains a base oil and hydroxytyrosol and / or an ester thereof.
- Hydroxytyrosol belongs to the family of natural polyphenols and has the following structural formula:
- Hydroxytyrosol is known to have antioxidant properties. However, it was surprising for the person skilled in the art that it has equivalent or, based on the concentration used, even better antioxidative properties than synthetic antioxidants usually used in practice, and that it can be added to common base oils without impairing their functional properties.
- esters of hydroxytyrosol can also be used.
- the hydroxytyrosol in the lubricant composition can also be only partially present as an ester.

- solubilized hydroxytyrosol is to be understood as meaning hydroxytyrosol, the solubility of which in relation to the base oil used has been increased by adding a solubilizing agent.
- the type and amount of the solubilizing agent depends, among other things, on the base oil used in each case, the desired solution properties of the hydroxytyrosol and the intended uses of the lubricant compositions.
- compounds which form a chemical compound with the hydroxytyrosol are also to be encompassed, for example with the formation of esters, with the term solubilizing agent.
