摘　　要：In this paper, a kinetics model for the liquid-phase oxidation of 2-methyl-6-acetyl-naphthalene to 2,6-naphthalene dicarboxylic acid catalyzed by cobalt-manganese-bromide is proposed. The effects of the reaction temperature, catalyst concentration and ratio of catalyst on the lime evolution of the experimental concentration for the constituents including raw material, intermediates and product are investigated. The model parameters are determined in a nonlinear optimization, minimizing the difference between the simulated and experimental time evolution of the product composition obtained in a semi-batch oxidation reactor where the gas and liquid phase were well nuxed. The kinetics data demonstrate that the model is suitable to the liquid-phase oxidation of 2-methyl-6-acetyl-naphthalene to 2,6-naphthalene dicarboxylic acid.在这篇论文，为到二羟基的酸由 cobalt-manganese-bromide 催化的 2,6 萘的 2-methyl-6-acetyl-naphthalene 的液体阶段氧化的一个动力学模型被建议。反应温度，催化剂集中和为包括原料，中介和产品的成分的试验性的集中的时间进化上的催化剂的比率的效果被调查。模型参数在非线性的优化被决定，最小化之间的差别模仿，产品作文的试验性的时间进化在气体和液体分阶段执行的一个半批氧化反应堆获得了很好被混合。Thekinetics 数据证明模型对到 2,6 萘的 2-methyl-6-acetyl-naphthalene 的液体阶段氧化合适二羟基的酸。
