ABSTRACT:
The invention relates to material containing aldosemarcaptals of the formula I ##STR1## wherein n can be an integer from 2 to 6, and wherein R.sup.1 and R.sup.2 are identical or different, and in each case are C.sub.1 -C.sub.18 -alkyl, which is unsubstituted, substituted or interrupted by --O-- or --S--, or are --(CH.sub.2).sub.r --CO--N(C.sub.1 -C.sub.17 -alkyl).sub.2, r being 1 or 2, or are phenyl, benzyl or --(CH.sub.2).sub.r --CO--O--R.sup.3, in which r can be 1 or 2 and R.sup.3 is an alkali metal or C.sub.1 -C.sub.14 -alkyl; also wherein R.sup.1 and R.sup.2 are --CH.sub.2 --CH(OH)--R.sup.4, in which R.sup.4 is hydrogen, or C.sub.1 -C.sub.16 -alkyl, unsubstituted or substituted by --OH, or --CH.sub.2 --Y--(C.sub.1 -C.sub.15 -alkyl), in which Y is --O-- or --S--; or wherein R.sup.1 and R.sup.2 together form --(CH.sub.2).sub.m --, in which m can be an integer from 2 to 4; to the use of the aldosemercaptals in lubricants and hydraulic fluids which can be based on oil or water or mixtures thereof, or in plastics; and to some novel aldosemercaptals.
