Aminomethyl derivatives of monothiocarbamates and dithiocarbamates as additives for lubricants

摘要

Composition containing one or more lubricants or hydraulic oils based on mineral oil, synthetic oils or mixtures thereof and at least one compound of the formulae I, II or III, ##STR1## in which R.sup. 1, R.sup.2, R.sup.3, R.sup.4 R.sup.5 and R.sup.6 independently of one another are C. sub.1 -C.sub.24 alkyl or C.sub.1 -C.sub.24 alkyl which can be substituted by oxo or thio groups, or C.sub.3 -C.sub.24 alkyl which can be interrupted by ##STR2## --S-- and/or --N(R.sup.8)-- in which R.sup. 8 is hydrogen or C.sub.1 -C.sub.12 alkyl and which can be substituted by oxo or thionogroups, or C.sub.2 -C.sub.24 alkenyl or phenyl or naphthyl which is unsubstituted or substituted by one or two C.sub.1 -C.sub.12 alkyl, C. sub.2 -C.sub.24 carboalkoxy or nitro groups; or are C.sub.7 -C. sub.10 phenylalkyl, and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 additionally are hydrogen, or R.sup.1 and R.sup.2, or R.sup.1 and R.sup.3 in the event that n is zero, together with the C atoms to which they are attached, form a 5-membered or 6-membered aliphatic ring which can be interrupted by --N(R.sup.8)-- in which R.sup.8 is as defined above, --O-- or --S-- and/or can be substituted by oxo or thiono groups; or in which R. sup.4 and R.sup.5, together with the N atom to which they are attached, form a 5-membered or 6-membered aliphatic-heterocyclic ring which, additionally to the N atom, can contain further heteroatoms [N(R.sup.8), O or S] and/or can be substituted byoxo or thiono groups, and in which R. sup.7 is also C.sub.2 -C.sub.12 alkylene which can be interrupted by -- N(R.sup.8)-- , --O-- and/or --S-- and/or can contain oxo or thiono groups, C.sub.6 -C. sub.15 cycloalkylene, C.sub.6 -C.sub.15 arylene, carbonyl or thiocarbonyl, or the group --N(R.sup.4)--R.sup.7 --N(R.sup.4)-- is a piperazine-1,4- diyl radical which can be substituted by one or more methyl groups, and X is also oxygen or sulfur and n is the numbers zero or 1, and also the compounds themselves, provided that they are novel.
