摘要
本文报道了用电子参数共振(EPR)对合成航空润滑油基础油二-2-乙基己基癸二酸酯中P, P '-二辛基二苯胺(' Irganox '，一种抗氧化剂)在加热过程中形成的自由基进行了初步研究。发现自由基的相对浓度与温度有关。结果似乎普遍支持这一概念，即有关抗氧化剂是某些活性过氧化自由基的有效清除剂。
EPR study of antioxidant action of P,p'‐dioctyldiphenyl amine
This paper reports the use of Electron Parametric Resonance (EPR) for preliminary investigation of radicals formed from P,p'-dioctyldiphenylamine (‘Irganox’, an antioxidant) during heating in a synthetic aviation lubricant base oil di-2-ethylhexylsebacate. Relative concentrations of radicals were found to be dependent on temperature. The results seem generally to support the concept that the antioxidant concerned is an effective scavenger of certain reactive peroxide radicals.
