    摘要: A composition comprisinga) a lubricant or a hydraulic fluid andb) at least one compound of the general formula I ##STR1## in which x=1 or 2 and,if x=1,R is as defined for R.sup.1 or R.sup.3 --O-- or,if x=2,R is as defined for R.sup.8, andR.sup.1 and R.sup.3 are, for example, alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, or alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl, which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH.sub.3 or e.g. --COOCH.sub.3, or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are interrupted by one or more groups from the series comprising --O--, --S--, --NH--, ##STR2## or alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are monosubstituted or polysubstituted by groups from the series comprising halogen, cyano, nitro, e.g. --OCH.sub.3 or e.g. --COOCH.sub.3 and interrupted by one or more groups from the series comprising --O--, --S--, --NH--, ##STR3## and R.sup.2 is NR.sup.4 R.sup.5, --OR.sup.6 or --SR.sup.7, andR.sup.4 and R.sup.5 are identical or different and are, for example, --H, alkyl, phenyl, naphthyl, aralkyl or alkaryl, orR.sup.4 and R.sup.5, together with the N atom linking them, form, for example, a piperidine or morpholine radical, andR.sup.6 and R.sup.7 can be alkyl which may be interrupted by one or more groups from the series comprising --O--, --S--, --NH--, ##STR4## or are, for example, phenyl, naphthyl, alkaryl or aralkyl, and R.sup.8 can be alkylene which may be interrupted by at least one --O-- group or alkylidene which may be interrupted by at least one --O-- group. Some of the compounds of the formula I are novel. The compositions show an improved stability towards oxidative degradation, confer protection under extreme pressures and reduce frictional wear.
