环己烯是一种易得的化工原料, 可通过苯选择性加氢来制备. 与环己烷相比, 引入烯烃官能团可使环己烯更易被氧化, 且反应位点选择性更佳. 因此, 环己烯氧化反应是合成尼龙-66系列产品及中间体的关键步骤, 有很好的工业应用价值. 近年来, 硒催化技术发展迅速, 与金属催化相比, 硒元素易代谢, 对生态安全, 且其催化氧化过程通常使用过氧化氢与分子氧为清洁的氧化剂, 对环境友好. 硒催化环己烯氧化技术, 有望应用于尼龙中间体合成中, 对均相以及非均相硒催化剂在该反应中的应用进行了综述, 从科学角度阐述其原理, 并对其产业化应用前景进行了展望.

Cyclohexene is an easily available chemical raw material that can be prepared by selective hydrogenation of benzene. Compared with cyclohexane, the introduction of the alkene functional group makes cyclohexene more active and can be oxidized with better selectivity. Therefore, the oxidation reaction of cyclohexene is the key step for the synthesis of nylon-66 series products and their intermediates. In recent years, selenium catalysis technology has developed rapidly. Compared with metal catalysis, selenium is easily metabolized and ecologically safe, and its catalytic oxidation process usually uses hydrogen peroxide and molecular oxygen as clean oxidants, which are environmentally friendly. The selenium-catalyzed oxidation technology of cyclohexene is expected to be applied in the synthesis of nylon intermediates. The relevant progresses including both homogeneous and heterogeneous catalysis are reviewed, the principle from a scientific perspective is expounded and prospects for its industrial application are provided.
