Claims
- 1. A lubricating composition containing a major amount of lubricating oil and a minor antiwear-antioxidant amount of an additive compound having the general formula: ##STR7## wherein: a. R is an organic radical selected from an aryl group selected from a benzene or an naphthalene group or an aralkyl group, wherein the aryl portion is selected from a benzene or a naphthalene group, in which the aryl or aralkyl groups contain up to 15 carbon atoms;
- b. R.sup.1 is hydrogen or an organic radical selected from an alkyl group, an alkenyl group, an aryl group selected from a benzene or a naphthalene group or an aralkyl group, wherein the aryl portion is selected from a benzene or a naphthalene group, in which the alkyl or alkenyl groups contain up to 32 carbon atoms and the aryl or aralkyl groups contain up to 15 carbon atoms; or
- c. R and R.sup.1 together with the nitrogen atom to which they are attached form a heterocyclic moiety selected from the group consisting of piperidine, morpholine and piperazine; and
- d. R.sup.2 and R.sup.3 are the same or different alkyl groups containing from 1 to 32 carbon atoms each.
- 2. A lubricating composition of claim 1 which comprises from 0.1 to 10 percent by weight of the additive compound.
- 3. A concentrate for addition to a lubricating composition, said concentrate comprising a minor amount of a mineral or synthetic oil and a major amount of a compound having the general formula: ##STR8## wherein: a. R is an organic radical selected from an aryl group selected from a benzene or a naphthalene group or an aralkyl group, wherein the aryl portion is selected from a benzene or a naphthalene group, in which the aryl or aralkyl groups contain up to 15 carbon atoms;
- b. R.sup.1 is hydrogen or an organic radical selected from an alkyl group, an alkenyl group, an aryl group selected from a benzene or a naphthalene group or an aralkyl group, wherein the aryl portion is selected from a benzene or a naphthalene group, in which the alkyl or alkenyl groups contain up to 32 carbon atoms and the aryl or aralkyl groups contain up to 15 carbon atoms; or
- c. R and R.sup.1 together with the nitrogen atom to which they are arranged form a heterocyclic moiety selected from the group consisting of piperidine, morpholine and piperazine; and,
- d. R.sup.2 and R.sup.3 are the same or different alkyl groups containing from 1 to 32 carbon atoms each.
- 4. The composition of claim 1 wherein both R and R.sup.1 are selected from an aryl group or an aralkyl group.
- 5. The composition of claim 1 wherein R and R.sup.1 together with the nitrogen to which they are attached form a heterocyclic moiety selected from the group consisting of piperidine, morpholine, and piperazine.
- 6. The concentrate of claim 3 wherein both R and R.sup.1 are selected from an aryl group or an aralkyl group.
- 7. The concentrate of claim 3 wherein R and R.sup.1 together with the nitrogen to which they are attached form a heterocyclic moiety selected from the group consisting of piperidine, morpholine, and piperazine.
