ABSTRACT:
Boron-containing compositions are prepared by the reaction of boric acid with the condensation product (which may be formed in situ) of a hydroxyaromatic compound)preferably a phenol) with an aromatic or aliphatic aldehyde (preferably formaldehyde). These compositions are useful as lubricant additives to inhibit oxidation, improve extreme pressure properties and decrease fuel consumption. They are especially useful as oxidation inhibitors in gear and bearing lubricants containing substantial amounts of sulfur and phosphorus compounds.
