基于不同路线合成环己基苯的催化剂研究进展OACSTPCD

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.
