Summary

  1. 1.

    IR and ESR spectroscopy have been used to investigate the mechanism of antioxidant action for the additive AKOR-1 in mineral oil. This additive has a dualistic effect: an inhibiting action in the initial stage of oxidation is replaced by an initiating action after the oil has been oxidized for 72 h.

     
  2. 2.

    In the presence of phenolic-type inhibitors together with the AKOR-1, a very pronounced synergistic antioxidant effect is observed; this is accompanied by an increase in the concentration of stable free radicals.

     
  3. 3.

    An explanation is suggested for the dualistic behavior of the AKOR-1 additive.
