Lubricant composition Full Description BACKGROUND OF THE INVENTION The present invention relates to lubricant compositions stabilized against oxidative degradation by incorporating certain amino stabilizers that are physically hindered. Lubricant formulations show sealing results .seals mags oo US Patents Nos. #777974 and 0777154 Adee Stabilization of lubricant formulations with a specific aromatic amine and at least one of the tested amines Her physical disability. The US patent No. OYTANNY discloses lubricants stabilized by the addition of a stereotactically inhibited amine and a phenol compound. ge 0 Stabilizers are known to be added to lubricants based on mineral or synthetic oils in order to improve their performance characteristics. These antioxidants are of particular importance. The oxidative decomposition of lubricants plays a role, I Fie, especially in motor oils, due to the high temperatures that prevail in the combustion chambers of engines and the presence - in addition to nitrogen oxides - of oxygen that act as catalysts. oxidation catalysts vo Yio.

The inhibited amines are effective lubricant stabilizers. However; It is not generally used due to adverse effects; For example: sealing aie, leaking, seal swell. General description of the invention The invention Jal relates to a process of stabilizing lubricant compositions using a special class of inhibited M-amine compounds. The current lubricant formulations are harmless in terms of seals. The present invention relates to a proven lubricant composition comprising: mineral oil, synthetic base oil, or a mixture of mineral oil and primer oil AEG ¢ and . At least one stereoisomerically hindered amine compound has formula I HN o “R (0 1) or where is a straight or branched alkyl group of 7 to 117 carbon atoms. R alkyl ic gana is a straight or branched group and consists, for example, of JY or 01 daa or 117 Jat Jae Jae Jar Jar day carbon atom. Three known stereoisomerally inhibited ak were prepared according to known methods in this field. For example (JB) the amine compounds that are currently inhibited are Yio.
