The composition contains at least one lubricant, for example based on mineral oils, synthetic oils or mixtures thereof, or a hydraulic fluid and a mixture of one or more compounds from series A) and one or more compounds from series B), the compounds of series A) being of the general formula …<IMAGE>… and the compounds of series B) being of the general formula …<IMAGE>… the radicals R<1> and R<1>' being, for example, -H or alkyl having 1 to 24 C atoms and n being 0.1 or 2, R<2> and R<3> being, for example, -H, alkyl having 1 to 24 C atoms or phenyl, or R<2> and R<3> together being an alkylene group, and R<4> being, for example, an alkyl group having 4-18 C atoms or a radical …<IMAGE>… in which R<5> can be an alkyl group, and R<4> being an alkylene group and Y being O or S. The mixture confers a high stability towards oxyidation on lubricant compositions. |
