Abstract
Metallic compounds of polyarylamine sulfides and polyarylamine-phenol sulfides are provided. Said compounds function as dispersants and lubricants are stabilized against oxidation and have their wear protection properties improved by adding thereto a property improving amount of one or more of said compounds.
Claims11
A lubricant composition comprising a major portion of an oil of lubricating viscosity or grease thereof and an oxidation property improving amount of the compound having the following formula:
- ##STR3## wherein n is an integer of from 1 to about 10;
- A is an aromatic hydrocarbon moiety;
- M is a polyvalent metal selected from the group consisting of Be, Mg, Ca, Ba, Mn, Co, Ni, Pd, Cu, Zn and Cd;
- X is oleate, phenyl phosphate, acetate, phosphate, sulfate, sulfonate, oxide, hydroxide or sulfite;
- R.sub.1 and R.sub.2 are alkyl of from 1 to about 10 carbon atoms, aryl, ##STR4## or combinations thereof;
- R' is alkyl of from 1 to about 10 carbon atoms, aryl or hydrogen;
- R.sub.3, r.sub.4, r.sub.5 and R.sub.6 are hydrogen, alkyl of from 1 to about 200 carbon atoms, aryl, alkyl-substituted aryl where the alkyl substituent is comprised of from 1 to about 200 carbon atoms or combinations thereof.
