Factors which affect the stability of highly unsaturated fatty acids. II. The autoxidation of linoleic and alkali conjugated acid in the presence of metallic naphthenates

Summary The addition of commercial paint driers to unconjugated linoleic acid increased the rate of diene conjugation during autoxidation and greatly lowered the amount of detectable peroxides. On the other hand, the addition of driers to the conjugated isomer lowered the amount of detectable peroxide but mildly promoted destruction of diene conjugation. The hydroperoxide decomposition role of driers is further supported. Metallic naphthenates increased the quantity of diene ketones in both unconjugated and conjugated acid though after a longer period of time in the latter case.
