    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.
