Abstract
In recent years, ionic liquid as a new green solvent has shown great potential in the field of electrochemical synthesis. The purpose of this study is to explore the application of ionic liquids in electrochemical synthesis, especially their advantages in improving reaction efficiency and selectivity. Through systematic screening and optimization of various ionic liquids, combined with electrochemical experimental techniques, we found that some ionic liquids can significantly reduce the overpotential of electrochemical reactions and improve the current efficiency. For example, using [BMIM][PF6] ionic liquid as solvent, the high efficiency electrooxidation of phenol to prepare benzoquinone was successfully achieved, and its current efficiency reached more than 90%, which was much higher than that of traditional organic solvents. In addition, the unique physical and chemical properties of ionic liquids, such as high electrical conductivity and low volatility, make them exhibit excellent stability in long-term electrochemical reactions. The experimental results show that ionic liquid can not only increase the reaction rate, but also effectively inhibit the occurrence of side reactions, so as to improve the selectivity of target products. This study provides a new idea and method for the application of ionic liquid in electrochemical synthesis, which has important theoretical significance and practical application value. Future studies will further explore the application potential of different types of ionic liquids in complex electrochemical systems in order to provide more possibilities for green chemical synthesis.
