Participants

Reaction Steps

Octyl-PANA (Product L06 from Ciba) and DODPA (Product L57 from Ciba) were dissolved in petroleum basestocks (Group 1 or 2) to produce oils containing 0.5% antioxidant. The voltammogiams in FIG. 1 were produced by dispensing 400 μL of oil into 5 mL of alcohol (ethanol) solution containing sodium phenate (0.05 molar shaking vial by hand, dispensing 50 μL of 2N aqueous HCl into the alcoholic solution to produce phenol from the sodium phenate in situ. The peak between 6 and 10 seconds in FIG. 1 is produced by the unreacted sodium phenate and indicates that the solution is still basic.
