摘　　要：借助于高效液相色谱技术(HPLC),研究了在Cu(Ⅱ)催化下,对氯苯酚和苯酚钾合成对苯氧基苯酚的反应动力学。结果表明:此合成反应对于对氯苯酚和苯酚钾的浓度分别为一级。总反应的表观活化能Ea=1.07.0 kJ/mol,指前因子A0=2.147×1010kg·mol-1·min-1, 反应的速度方程为: -(d[p-ClC6H4OH]/dt)=2.147 ×1010×exp((107.0×103)/RT)·[p-ClC6H4OH][C6H5OK]。The kinetics of the reaction of p-chlorophenol with potassium phenolate catalyzed by Cu(Ⅱ)-complex was investigated by HPLC technique. The order of reaction was found to be one with respect to the concentrations of p-chlorophenol [A] or potassium phenolate [B] by the isolation method. The Arrhenius parameters were determined for the overall reaction:Ea = 1.17.0 kJ/mol and A0=2.147×1010 kg·mol-1 ·min-1. The empirical rate law for this reaction is: -(d[p-ClC6H4OH]/dt)=2.147 × 1010×exp((107.0×103)/RT)·[p-ClC6H4OH][C6H5OK].
