环己基苯（CHB）是一种重要的化学中间体，具有特殊的物理化学性能，可用作锂离子电池的电解质添加剂，少量添加即可防止过度充电并确保电池的循环性能和寿命；CHB在用于过氧化反应合成苯酚中时可生成另一种重要的有机化工产品——环己酮。介绍了3种合成CHB方法中使用的催化剂，这3种方法包括苯与烷基化试剂的傅克烷基化反应、联苯选择性加氢反应以及苯加氢烷基化反应；指出了开发兼具高酸量和高介孔体积的沸石分子筛催化剂是苯加氢烷基化制备CHB的关键。

Cyclohexylbenzene (CHB) is an important chemical intermediate with special physicochemical properties.It can be used as electrolyte additive for lithium ion battery. A small amount can prevent overcharging and ensure battery cycle performance and life. CHB can generate another important organic chemical product, cyclohexanone, when used in the synthesis of phenol through peroxidation reaction. Introduced the catalysts used in three methods for synthesizing CHB. These three methods include Fouke alkylation of benzene with alkylation reagent, selective hydrogenation of biphenyl, and alkylation of benzene with hydrogen. It is pointed out that the development of zeolite molecular sieve catalysts with high acid content and high mesoporous volume is the key to the preparation of CHB by benzene hydroalkylation.
