Abstract

The reactivity of amines towards tert‐butoxy radicals depends upon the amine ionization potential and the solvent, indicating that polar structures contribute to the reactivity of these compounds. Nevertheless, the dependence with the amine potential is smaller than the one obtained for the quenching of carbonyl excited states by amines and other factors as the strength of the broken hydrogen bond and steric hindrance are also significant in determining the rate of the process.

Jayanty, Simonaitis and Heicklen [l] have found that amines delay the conversion of NO t~ NO2 when mixtures of C3H6, NO, NOz, and 0 2 were irradiated. The inhibition was assumed to be due to the trapping of some of the free radicals that carry out the oxidation process, but the different inhibiting
