Document Type and Number:
Japanese Patent JP2684103
Kind Code:
B2
Abstract:
Composition containing
a) a lubricant or a hydraulic fluid and
b) at least one compound of the general formula I
where x = 1 or 2 and,
if x = 1,
R has the meaning of R<1> or R<3>-O-, or,
if x = 2,
R has the meaning of R<8> and
R<1> and R<3> denote, for example, alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl or denote alkyl, cycloalkyl, alkenyl, phenyl, naphthyl, aralkyl or alkaryl which are substituted by one or more groups from the series comprising halogen, cyano, nitro, e.g. -OCH3 or e.g. -COOCH3, or denote alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are interrupted by one or more groups from the series comprising -O-, -S-, -NH-,
or denote alkyl, cycloalkyl, alkenyl, aralkyl or alkaryl which are substituted by one or more groups from the series comprising halogen, cyano, nitro, e.g. -OCH3 or e.g. -COOCH3 and are interrupted by one or more groups from the series -O-, -S-, -NH-,
and
R<2> has the meaning of NR<4>R<5>, -OR<6> or -SR<7>, and
R<4> and R<5> are identical or different and denote, for example, -H, alkyl, phenyl, naphthyl, aralkyl or alkaryl, or
R<4> and R<5>, together with the N atom connecting them, form, for example, a piperidine or morpholine radical, and
R<6> and R<7> can denote alkyl which is optionally interrupted by one or more groups from the series comprising -O-, -S-, -NH-,
or represent, e.g. phenyl, naphthyl, alkaryl or aralkyl, and
R<8> can be an alkylene which is optionally interrupted by at least one -O- group or an alkylidene which is optionally interrupted by at least one -O- group.
Some of the compounds of the formula I are novel. The compositions have an improved stability to oxidative degradation, have a protective effect at extreme pressures and reduce frictional wear.
