摘要

1. An antiwear compound selected from phosphorus compounds of the general formula (2) or their salts with metals of the general formula (3) where, in the general formulas (2) and (3), R and R are each independently a group selected from the group consisting of hydrogen, an alkyl group with 1-30 carbon atoms, a cycloalkyl group and an aryl group, and where X is O or S and M is a metal atom, preferably selected from zinc, molybdenum, copper and tungsten. 2. A lubricating composition comprising a base oil and at least one antiwear compound according to claim 1, and wherein the content of at least one antiwear compound is from 0.01 to 10% by weight based on elemental phosphorus relative to the total amount of lubricant compositions. 3. The use of antiwear compounds according to claim 1 for improving antiwear properties. The use of the lubricating composition according to claim 2 for improving antiwear properties.
