Claims
- 1. A lubricating composition, comprising a major amount of an oil of lubricating viscosity and a minor amount of a mixture of metal salts of phosphorodithioic acids prepared by the reaction of a metal or basic metal compound; a phosphorus sulfide; and
- (I) a mixture of low hydrocarbyl arene alcohols represented by the following formula (B): ##STR5## wherein (R) is a low hydrocarbyl group having from 1 to 4 carbon atoms and m is a number from 0-3 such that the low hydrocarbyl group (R) contains an overall average number of from 0.1 to about 3.5 carbon atoms in the mixture of low hydrocarbyl arene alcohols; and
- (II) at least one aliphatic alcohol (H) containing from 3 to about 22 carbon atoms;
- wherein the mixture of low hydrocarbyl arene alcohols is present in an amount of from about 50% to about 85% equivalents and the aliphatic alcohol (H) is present in an amount from about 15% to about 50% equivalents based on the total equivalents of (B) and (H).
- 2. The composition as claimed in claim 1 wherein the aromatic group has an average carbon substituent from about 0 to about 4 carbon atoms and the aliphatic group is an alkyl group containing from about 4 to about 14 carbon atoms.
- 3. The composition claimed in claim 1 wherein the metal is selected from the group consisting of zinc, copper, nickel, cobalt, iron, potassium, tin, sodium, calcium, and combinations thereof.
- 4. The composition as claimed in claim 1, wherein the aromatic group has an average carbon substituent of from 2 to about 3 carbon atoms and wherein the metal is zinc.
- 5. The lubricating composition of claim 1 wherein the low hydrocarbyl arene alcohol (B) is present in an amount from about 70% to about 80% equivalents and the aliphatic alcohol (H) is present in an amount from about 20% to about 30% equivalents based on the total equivalents of (B) and (H).
- 6. A concentrate, comprising:
- a liquid organic diluent and from about 3 to about 90 percent by weight of a mixture of metal salts of phosphorodithioic acids prepared by the reaction of a metal or basic metal compound; a phosphorus sulfide; and
- (I) a mixture of low hydrocarbyl arene alcohols represented by the following formula (B): ##STR6## wherein (R) is a low hydrocarbyl group having from 1 to 4 carbon atoms and m is a number from 0-3 such that the low hydrocarbyl group (R) contains an overall average number of from 0.1 to about 3.5 carbon atoms in the mixture of low hydrocarbyl arene alcohols; and
- (II) at least one aliphatic alcohol (H) containing from 3 to about 22 carbon atoms; wherein the mixture of low hydrocarbyl arene alcohols is present in an amount of from about 50% to about 85% equivalents and the aliphatic alcohol (H) is present in an amount from about 15% to about 50% equivalents based on the total equivalents of (B) and (H).
- 7. The concentrate of claim 6 wherein the low hydrocarbyl arene alcohol (B) is present in an amount from about 70% to about 80% equivalents and the aliphatic alcohol (H) is present in an amount from about 20% to about 30% equivalents based on the total equivalents of (B) and (H).
