A metal working lubricant comprising a major amount of lubricating oil and a minor amount, effective to improve the rust inhibiting and extreme pressure properties thereof, of a composition comprising:
- (A) A phosphorus-containing composition comprising at least one compound having the formula
- (R.sup.1 -Ar.sup.1 OR.sup.2 O).sub.2 POH
- wherein:
- Each R.sup.1 is independently an aliphatic hydrocarbon-based radical having from about 4 to about 100 carbon atoms;
- each R.sup.2 is independently an ethylene, trimethylene, lower alkyl-substituted ethylene or lower alkyl-substituted trimethylene radical;
- and
- each Ar.sup.1 is independently an aromatic radical;
- and
- (B) a chlorinated wax.
A metal working lubricant comprising a major amount of a lubricating oil and a minor amount, effective to improve the rust inhibiting and extreme pressure properties thereof, of a composition comprising:
- (A) A phosphorus-containing composition prepared by reacting at least one alcohol of the formula R.sup.1 -Ar.sup.1 -OR.sup.2 OH with at least one phosphorus halide of the formula PZ.sub.3, wherein:
- R.sup.1 is an aliphatic hydrocarbon-based radical having from about 4 to about 100 carbon atoms;
- R.sup.2 is an ethylene, trimethylene, lower alkyl-substituted ethylene or lower alkyl-substituted trimethylene radical;
- Ar.sup.1 is an aromatic radical;
- and
- Z is chlorine or bromine;
- and
- (B) a chlorinated wax.
