    摘要： New reaction products obtained by reacting (1) a hindered phenol, (2) a borating agent and (3) a hydrocarbyl carboxylate are described. The preferred reaction sequence involves, first, the reaction of (1) and (2), then reacting the product obtained with the hydrocarbyl carboxylate.Also described are lubricant or liquid fuel compositions containing a major proportion of lubricant or fuel and an antifriction, anticorrosion or fuel reducing amount of the reaction product of this invention and a method of reducing fuel consumption in an internal combustion engine by lubricating the engine therewith.

    摘要： The present invention relates to 9-hydroxy-9,10-boroxarophenanthrene compositions which are particularly suitable additives to improve the stability of lubricating oils and fuel compositions. More particularly, esters of 9-hydroxy-9,10-boroxarophenanthrene which are formed from hindered phenols have been found to have improved and sustained oil solubility and comprise hydrolytically stable antioxidants which, in minor amounts, have been found to impart to oils of lubricating viscosity a high level of protection against oxidative degradation.
