with the kinetics of bromine addition to unsaturated compounds in presence of added bromide ions at 22, 30, 38, 46, and 54 °C. The substrates used were acrylamide (AAm), methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA), t-butyl acrylate (tBA), methacrylamide (MAAm), methyl methacrylate (MMA), ethyl methacrylate (EMA), methyl crotonate (MC), and ethyl crotonate (EC). The kinetics was followed
本文讨论了在 22、30、38、46 和 54 °C 下,在添加溴离子存在下,溴与不饱和化合物的加成动力学。所用基材为丙烯酰胺(AAm)、丙烯酸甲酯(MA)、丙烯酸乙酯(EA)、丙烯酸丁酯(BA)、丙烯酸叔丁酯(tBA)、甲基丙烯酰胺(MAAm)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸乙酯(EMA) )、巴豆酸甲酯 (MC) 和巴豆酸乙酯 (EC)。通过电位测定法跟踪动力学。计算并比较激活参数(ΔH\eweq、ΔS\eweq和ΔG\eweq)。溴代醇与二溴化物的产物比率的估计表明产物形成与底物的反应性之间不存在任何相关性。观察到的参数与建议的反应机制有关。
