ABSTRACT:
Certain heretocyclic hydrogen phosphonates are disclosed as having utility in functional fluids, particularly synthetic lubricants and/or water-based functional fluids. Antiwear characteristics and other properties are improved by the blending of additives such as spiro-bis-hydrogen phosphonate and cycloneopentyl hydrogen phosphonate with non-petroleum base stocks such as water, phosphate esters, and mixed polyalphaolefins/polyol esters. Preferred formulations are disclosed.
