Abstract
A lubricant including a compound of the formula: ##STR1## wherein 4, 5 or 6 of the substituents X.sub.1 to X.sub.6 can be --SR, --SO.sub.2 R or --SOR and the other substituents can be --H, --Cl, --F, --OH, --SH, --R, --OR, --COOR or --OOCR wherein R is independently, at each occurrence, unsubstituted or substituted alkyl, of 1 to 18 carbon atoms, said substitution consisting of fluorine substitution of hydrogen, --O-- substitution of --CH.sub.2 --, --S-- substitution of --CH.sub.2 -- and mixtures thereof, said --O-- and --S-- substitutions being selected so that --O-- atoms are not directly bonded to each other. The invention further includes a method of lubricating with the lubricant.
Claims19
A lubricant comprising at least one lubricant additive and a compound of the general formula:
- ##STR10## wherein 4, 5 or 6 of the substituents X.sub.1 to X.sub.6 can be --SR, --SO.sub.2 R or --SOR
- and the other substituents can be
- --H, --Cl, --F, --OH, --SH, --R, --OR, --COOR or --OOCR
- wherein R is independently, at each occurrence, unsubstituted or substituted alkyl, of 1 to 18 carbon atoms, said substitution consisting of fluorine substitution of hydrogen, --O-- substitution of --CH.sub.2 --, --S-- substitution of --CH.sub.2 -- and mixtures thereof, said --O-- and --S-- substitutions being selected so that --O-- atoms are not directly bonded to each other.
A method for lubrication between surfaces which comprises applying a lubricant between the surfaces which includes a compound of the general formula:
- ##STR11## wherein 4, 5 or 6 of the substituents X.sub.1 to X.sub.6 can be --SR, --SO.sub.2 R or --SOR
- and the other substituents can be
- --H, --Cl, --F, --OH, --SH, --R, --OR, --COOR or --OOCR
- wherein R is independently, at each occurrence, unsubstituted or substituted alkyl, of 1 to 18 carbon atoms, said substitution consisting of fluorine substitution of hydrogen, --O-- substitution of --CH.sub.2 --, --S-- substitution of --CH.sub.2 -- and mixtures thereof, said --O-- and --S-- substitutions being selected so that --O-- atoms are not directly bonded to each other.
