摘要
运用主成分分析最小二乘分析和聚类分析对二氧化氯和24种酚类化合物氧化动力学数据进行了模式识别研究,结果表明电子效应是影响二氧化氯与酚类化合物反应速度的主要因子,反应过程为亲电自由基氧化,反应中心为酚盐负离子中的氧负离子,给电子基团对反应进行有加速作用,吸电子基团减缓反应的进行.
Pattern recognition of oxidation kinetics between chlorine dioxide and 24 substituted phenolic compounds were studied through bases analysis, regression analysis and cluster analysis. The results showed that the electronic effect was the control factor which affected the reaction rate of chlorine dioxide and phnolic compounds. The reaction of chlorine dioxide and substituted phenols was of radical oxidation mechanism, and the reaction center was the negative oxygen in phenoxide. Electron donor accelerated, while electron acceptor reduced, the reaction rate.
