Abstract
The participation of semiquinone free radicals during the reaction of ascorbic acid with acidified sodium nitrite has been demonstrated by ESR spectroscopy unambiguously for the first time. Scavenging of the nitrosating agent, reflected by the observed free radical concentration, unexpectedly occurs with scarcely varying efficiency over the pH range 0.1--4.5.
摘要
通过电子自旋共振光谱法首次明确证实了抗坏血酸与酸化亚硝酸钠反应过程中半醌自由基的参与。由观察到的自由基浓度反映出的亚硝化剂清除情况，在0.1 - 4.5的pH范围内，清除效率几乎不变，这一点出乎意料。
