Abstract
A phosphate complex of a borate ester provides wear- and friction-reducing performance to an engine or driveline device. The complex may be a pyroborate-hydrocarbyl-substituted phosphate adduct. Boric acid may be reacted with a diol to form an ester, then reacting said ester with an ammonium salt of phosphoric acid or a hydrocarbyl-substituted phosphoric acid.
