摘　　要：采用Fenton试剂探索苯酚衍生物的氧化反应动力学,考察了反应时间、温度及取代基等对降解速率的影响。结果表明,随着反应时间增加和温度升高,化合物的氧化速率明显加快;取代基的位置与反应速率有一定的关系。在25~45℃的温度范围内,其氧化降解符合假一级反应动力学模型,获得了各衍生物的活化能（49.05~65.19kJ/mol）、活化焓（46.54~62.67kJ/mol）及Gibbs自由能（95.94~96.62kJ/mol）数据。Reaction kinetics study on oxidative degradation of phenol derivatives was carried out by Fenton reagent.The effects of reaction time,temperature and substituent on degradation were investigated.The results showed that the oxidative degradation rates of the compounds increase obviously with increasing both the reaction time and temperature.The positions of the substituents have a certain relationship with the reaction rates.The kinetics equation of the compounds with Fenton reagent was described with a pseudo-first-order kinetics model at the temperature of 25-45℃. The data of activation energy（49.05-65.19kJ/mol）,activation enthalpy（46.54-62.67kJ/mol）and Gibbs free energy（95.94-96.62kJ/mol）were obtained.
