Synthesis and Characterization of Oil Lubricant Antioxidant Degradation Products

Antioxidants are an example of additives added to lubricants as a sacrificial substance, which extend the lifespan by preferentially being oxidized over the lubricant. GasTops Ltd. is interested in predicting the remaining life of a lubricant by monitoring the quantity of antioxidant degradation products. An antioxidants of interest is N-phenyl-1-aminonaphthalene (PAN). Three major oxidation products of PAN have been identified, synthesized, and isolated: C-C coupled PAN dimer, C-N coupled PAN dimer, and naphthyl oxidized PAN (Fremy’s PAN). Other products include N-O radical PAN and phenyl oxidized PAN. Attempts to independently synthesize samples of these PAN derivatives resulted in the unexpected syntheses of other known PAN derivatives. Preparation of C-C PAN resulted in the synthesis of Fremy’s PAN as a by-product. Synthesis of C-N PAN resulted in the synthesis of C-C PAN and Fremy’s PAN. Synthesis of N-O radical PAN resulted in the production of C-C PAN and Fremy’s PAN.
