Nitrogen dioxide radical (NO2.) is known as a toxic agent produced in the metabolism of nitrates and nitrites. By the use of the pulse radiolysis technique, the mechanism of the reaction of NO2. radical with hydroxycinnamic acid derivatives (HCA) was studied and the rate constants have been measured. The rate constants were found to be 7.4 x 10(8), 7.2 x 10(8), 8.6 x 10(8) dm3 mol(-1) s(-1) for ferulic acid, sinapic acid and caffeic acid, respectively. The reactions produce the corresponding phenoxyl radical.
二氧化氮自由基（NO2.）是硝酸盐和亚硝酸盐代谢过程中产生的一种有毒物质。利用脉冲辐解技术，研究了NO2.自由基与羟基肉桂酸衍生物（HCA）的反应机理，并测定了反应速率常数。结果发现，阿魏酸、芥子酸和咖啡酸的反应速率常数分别为7.4×10(8)、7.2×10(8)、8.6×10(8) dm3 mol(-1) s(-1)。这些反应会生成相应的苯氧自由基。
