Kinetics of oxidation of indole-3-acetic acid (IAA) by peroxomonosulphate (PMS) in aqueous acetonitrile medium has been investigated. The reaction follows a total second order, first order each with respect to [IAA] and [PMS]. The rate of the reaction was not affected by added [H+]. Variation of ionic strength (μ) had no influence on the rate. Increase of percentage of acetonitrile decreased the rate
研究了在水性乙腈介质中过氧单硫酸盐 (PMS) 氧化吲哚-3-乙酸 (IAA) 的动力学。反应遵循总的二级,第一级每个相对于[IAA]和[PMS]。反应速率不受添加的 [H+] 的影响。离子强度(μ)的变化对速率没有影响。乙腈百分比的增加降低了该速率。不存在任何聚合表明非自由基途径。已经计算了活化和热力学参数。提出了基于这些观察的合适的动力学方案。发现 PMS 对 IAA 的反应性高于与过二硫酸盐的反应性。© 2002 Wiley Periodicals, Inc. Int J Chem Kinet 34: 569–574, 2002
