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.

4,6-二叔丁基-2,3-二羟基苯甲醛亚甲胺衍生物对涉及烷基和-羟基烷基自由基的辐射诱导反应的影响

摘要研究了4,6-二叔丁基-2,3-二羟基苯甲醛的亚甲胺衍生物对脱氧正己烷和乙醇辐射解产物生成的影响。结果表明，所测化合物中的儿茶酚部分对其与碳中心自由基的反应没有显著影响。醛胺对α-羟基烷基自由基的清除活性高，对烷基自由基的清除活性低。在分子侧片段中引入额外的自由基抑制基团- oh， - sh， - no2和= N-NH -，导致对各种碳中心自由基的抗自由基活性显著增加。
