Abstract
A composition containing a lubricant or a hydraulic fluid and at least one compound of the formula I ##STR1## in which both R.sup.1, independently of one another, are a hydrogen atom, a metal cation, NH.sub.4.sup..sym., primary, secondary, tertiary or quaternary ammonium, linear or branched C.sub.1 -C.sub.24 -alkyl, unsubstituted or C.sub.1 -C.sub.18 -alkyl-substituted cycloalkyl or cycloalkylalkyl having 3 to 7 ring C atoms, C.sub.7 -C.sub.16 -aralkyl or C.sub.8 -C.sub.40 -alkaralkyl, where C.sub.1 -C.sub.24 alkyl may be substituted by --NR.sup.4 R.sup.5, --N.sup..sym. R.sup.4 R.sup.5 R.sup.6, --OR.sup.7, --SR.sup.7, --(C.sub.m H.sub.2m O).sub.n R.sup.8, --C(O)OR.sup.9 or C.sub.1 -C.sub.20 -acyloxy, in which R.sup.4, R.sup.5 and R.sup.6, independently of one another, are a hydrogen atom or unsubstituted or --OH-substituted C.sub.1 -C.sub.20 -alkyl, or R.sup.4 and R.sup.5 together are tetramethylene, pentamethylene or 3-oxapentylene, R.sup.7 is a hydrogen atom, linear or branched C.sub.1 -C.sub.18 -alkyl, unsubstituted or C.sub.1 -C.sub.12 -alkylsubstituted cyclohexyl, phenyl or benzyl, R.sup.8 is a hydrogen atom, C.sub.1 14 C.sub.18 -alkyl or C.sub.1 -C.sub.20 -acyl, and R.sup.9 is a hydrogen atom, the radical, reduced by one hydroxyl group, of a monohydric alcohol, a metal cation, or primary, secondary, tertiary or quaternary ammonium, m is an integer from 1 to 6, and n is a number from 1 to 20, R.sup.2 and R.sup.3, independently of one another, are a hydrogen atom or linear or branched C.sub.1 -C.sub.20 -alkyl, or R.sup.2 and R.sup.3 together are --C.sub.p H.sub.2p --in which p is an integer from 2 to 9. The compounds of the formula I are suitable as anti-wear agents and as high-pressure additives for lubricants and hydraulic fluids.
