Abstract
The effects of azomethine derivatives of 4,6-di-tert-butyl-2,3-dihydroxybenzaldehyde on the formation of radiolysis products of deaerated n-hexane and ethanol have been studied. It was shown that the catechol moiety in the tested compounds did not significantly affect their reactions with carbon-centered radicals. The aldimine group exhibited high activity as an α-hydroxyalkyl radical scavenger and low activity as a scavenger of alkyl radicals. The introduction of additional radical-inhibiting groups –OH, –SH, –NO2, and =N–NH– into the side fragment of a molecule led to a significant increase in the antiradical activity with respect to various types of carbon-centered radicals.
