    摘要: Composition containing 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) having the general formula ##STR1## and the compounds of series (B) having the general formula ##STR2## in which the radicals R.sup.1 and R.sup.1 ' are, for example, --H or alkyl having 1 to 24 C atoms and n is 0, 1 or 2, R.sup.2 and R.sup.3 are, for example, --H, alkyl having 1 to 24 C atoms or phenyl or R.sup.2 and R.sup.3 together are an alkylene group, and R.sup.4 is, for example, an alkyl group having 4-18 C atoms or a radical ##STR3## in which R.sup.5 can be an alkyl group, and R.sup.4' is an alkylene group and Y is O or S. The mixture imparts a high stability towards oxidative degradation to lubricant compositions.
