    Diphenylamine Antioxidants - Oronite

    Antioxidants are a class of chemicals which inhibit oxidation of lubricating oils. By controlling oxidation, antioxidants prevent oil breakdown and thickening, and help engines run longer and smoother. Antioxidants such as diphenylamine (DPA) perform their function by reacting with the free radicals generated by

    Determination of Diphenylamine Antioxidants in Wastewater

    Diphenylamine derivatives are widely used as antioxidant additives in vehicle engine oils, commercial/industrial lubricants, and products composed of rubber. Their presence in the environment results primarily from human activity, and there are no known environmental measurements of these substances in any media. In this study, 17 components of three diphenylamine substances, 2-propanone

    Diphenylamine: An unusual antioxidant

    Diphenylamine (DPA) has been utilized as an antioxidant in studies of lipid peroxidation. Using peroxidizing red blood cell (RBC) membranes, we find that DPA actually promotes lipid hydroperoxide (LOOH) formation and oxygen consumption while markedly inhibiting generation of thiobarbituric acid reactive substances (TBARS).
