ABSTRACT:
A boron-containing heterocyclic compound prepared by reacting a primary amine or ammonia with an alkylene oxide or epoxide and then reacting concurrently or subsequently this reaction intermediate with a boric acid. This boron-containing heterocyclic compound may further be reacted with a metal, metaloid or other metal compound and even further contain sulfur, such as a sulfide group.
The boron-containing heterocyclic compound provides extreme pressure anti-wear properties when provided in a lubricating composition. The lubricating composition may also comprise anti-oxidants, copper corrosion inhibitors, and lead corrosion inhibitors. The anti-wear properties of a lubricating composition can be enhanced using the borates of the present invention in conjuction with a copper compound.
