摘　　要：计算了H2O2氧化环己烷合成己二酸体系中各反应的标准摩尔反应焓变、标准摩尔吉布斯自由能变及标准平衡常数.结果表明,在温度298.15 K-373.15 K范围内,各反应均为放热反应,在达平衡时几乎均可进行到底,制备己二酸适宜的H2O2与环己烷化学摩尔计量比为5:1~6:1.A detailed thermodynamic calculation for the reactions of oxidation of cyclohexane into adipic acid and other products was conducted , involvingΔr Hmθ,Δr Gmθand Kθ.The results showed that all five oxidation re-actions mentioned are exothermal between 298.15 K^373.15 K, and the reactants will be consumed completely when equilibrium reach .The appropriate stoichiometric ratio of hydrogen peroxide/clohexane for producing adip-ic acid is 5：1~6：1.
