负载型离子液体在C-H键电氧化活化中的应用研究
Application of Composite Ionic Liquid in Electro-Oxidation Activation of a C-H Bond
摘要
Abstract
In this paper,the ionic liquid/carbon nanotube composite material was prepared through modifying the ionic liquid 1-ethyl-3-methylimidazolium acetate to multi-walled carbon nanotubes.The electro-oxidation properties ofp-methoxy toluene (p-MT) were studied using the composite as an electrolyte.The effects of scanning speed,temperature and substrate concentration were studied by cyclic voltammetry and chronoamperometry.The electrochemical kinetics ofp-MT in this system was also studied.The results showed that the electrochemical oxidation ofp-MT in the composite electrolyte solution was irreversible.The process was mainly controlled by diffusion,and the diffusion coefficient (D) was 7.69 x 10-10 cm2· s-1.Increasing the reaction temperature and the concentration of substrate could promote the electro-oxidation of the C-H bond to the corresponding aldehyde,and the selectivity ofp-methoxybenzaldehyde (p-MBA) could improve to 95％.The electrolysis in one-pot was more efficiency and achieved better selectivity than that in the H-type.关键词
