The rate constants for the reaction of primary alkyl radicals with substituted phenolic compounds have been measured in benzene or toluene at room temperature by using the radical clock technique. With three representative phenols, containing in the ortho positions substituents of different size, the kinetics of the hydrogen transfer to alkyl radicals was studied at different temperatures to obtain the
伯烷基自由基与取代酚类化合物反应的速率常数已在室温下在苯或甲苯中使用自由基时钟技术测量。使用三种具有代表性的苯酚,在邻位含有不同大小的取代基,在不同温度下研究了氢转移到烷基的动力学以获得相应的阿伦尼乌斯参数。还在作为氢键受体的六种不同溶剂中研究了动力学溶剂对与 α-生育酚反应的影响,同时研究了与 2,4,6-三甲基苯酚和 2,6-二叔丁基苯酚在甲苯和γ-戊内酯。对于某些酚类,还研究了自聚集对动力学参数的影响。
