Compositions comprising 2,2',2"-nitrilotriethanol cyclometalates

Abstract

Compositions comprising a) a functional liquid or an internal combustion engine fuel and b) at least one compound of the general formula I ##STR1## wherein R.sub.1 is --(CH.sub.2 --X).sub.n R, where X=--S-- or --O--, n=0 or 1 to 18 carbon atoms, a phenyl group, a phenyl group which is substituted by at least one C.sub.1 -C.sub.18 alkyl group, a phenyl-C.sub.1 -C.sub.4 alkyl group or a phenyl-C.sub.1 -C.sub.4 alkyl group which is substituted by at least one C.sub.1 -C.sub.4 alkyl group, or R.sub.1 is an alkyl group of 1 to 18 carbon atoms which is substituted by at least one OH group, or R.sub.1 is a ##STR2## group in which the alkyl moiety contains 1 to 18 carbon atoms, and R.sub.2 and R.sub.3 are the same or different and are --H or, independently of R.sub.1, have the same meanings as R.sub.1, and M is B, Al, Fe, Cr, Sb or Bi, or M is a group M'--R' or a group M'--OR", where M' is Ti, Zr or Sn, and R' and R" is C.sub.1 -C.sub.18 alkyl or R' is ##STR3## wherein M' is defined above, and R.sub.1 ', R.sub.2 ' and R.sub.3 ' have the meanings of R.sub.1, R.sub.2 and R.sub.3, or R" is Li, Na or K or is ##STR4## wherein M' is as defined above and M" is Mg, Ca, B, Al, Fe, Cr, Sb, Bi, Zn, Ti, Ni or Cu, q has the valence of M", and R.sub.1 ', R.sub.2 ' and R.sub.3 ' have the respective meanings of R.sub.1, R.sub.2 and R, or M is --VO. The compounds of formula act, for example, in lubricants as antiwear additives and extreme pressure additives, and also as stabilizers for natural or regenerated polymers.
