Conclusions
-
1.
A plot of the synergistic effect against the total inhibitor concentration for ethylbenzene oxidation in the presence of neozone-D—2,6-di-tert-butylphenol passes through a maximum. The results, obtained here are consistent with a mechanism involving regeneration of the more active inhibitor and chain extension through radicals of this compound.
-
2.
For each of the systems studied here there was a limiting total inhibitor concentration beyond which the inhibiting action of the mixture was lower than that of the component whose radicals were not involved in oxidation chain extension.
-
3.
With increasing [InH]tot, the maximum on the τ vs mixture composition curved moved to higher phenol concentrations in the inhibitor mixture.
-
4.
For inhibition by the component whose radicals are involved in extension of the oxidation chain, the τ vs [InH] curve may pass through a maximum.
