  The reaction of ω-(4-hydroxyaryl)haloalkanes with various nitrogen-containing agents afforded primary, secondary, and tertiary amino derivatives of 2,6-dialkylphenols. For the compounds synthesized, the reaction rate constants with peroxide radicals were measured for cumene and methyl oleate oxidation. The total inhibitory activity in the model reactions of thermal autooxidation of lard and hexadecane was studied. The rate constants of alkyl(hydroxylaryl)amines are the same as those of the corresponding alkylphenols, whereas the total inhibitory activity of some alkyl(hydroxylaryl)amines exceeds substantially that for alkylphenols.

  ω-(4-羟基芳基)卤代烷烃与各种含氮剂反应后，可得到 2,6 二甲基苯酚的伯氨基、仲氨基和叔氨基衍生物。对于合成的化合物，测量了它们与过氧化自由基在积雪烯和油酸甲酯氧化过程中的反应速率常数。研究了猪油和十六烷热自氧化模型反应中的总抑制活性。烷基（羟基芳基）胺的速率常数与相应烷基酚的速率常数相同，而某些烷基（羟基芳基）胺的总抑制活性大大超过了烷基酚。
