Antioxidant compositions and industrial fluids containing same

摘要

The present invention provides new compounds that can be used as antioxidants for either molecules that do not conation ester groups or esters of alcohols that contain two or more ester groups per molecule wherein at least two of the ester groups are on adjacent carbons in the alcohol moiety. Copper ions can enhance the antioxidization activity of the new compounds. Compositions containing one of the new compound and methods of using the new compounds are disclosed.
