Abstract
With the deepening of the concept of green chemistry and sustainable development, ionic liquids, as a new catalytic medium and catalyst, show unique advantages and broad application prospects in catalytic hydrogenation reaction. In this paper, the latest research progress of ionic liquid in catalytic hydrogenation reaction is reviewed, and its application effect and performance characteristics as catalyst, solvent or stabilizer in various hydrogenation reactions are discussed. Ionic liquids play an important role in catalytic hydrogenation due to their unique properties such as low vapor pressure, high thermal stability, chemical stability and designability. As a catalyst, ionic liquids can significantly improve the activity and selectivity of hydrogenation reactions by forming intermediates with reactants or providing active sites. At the same time, the recyclability and reusability of ionic liquids also reduce production costs and meet the requirements of green chemistry. In hydrogenation reactions, ionic liquids can also be used as solvents or stabilizers to optimize the catalytic process by regulating the polarity and mass transfer efficiency of the reaction system. For example, functionalized ionic liquids can stabilize and disperse nanocatalysts by introducing specific functional groups, thus improving catalytic activity and stability. In addition, the development of supported ionic liquid technology has further improved the application effect of ionic liquid in catalytic hydrogenation reaction, and reduced the difficulty and cost of industrial applications by reducing the amount of ionic liquid and improving the efficiency of product separation. The results show that ionic liquids exhibit excellent catalytic activity and product selectivity in the hydrogenation of olefins, aromatics, unsaturated aldehydes and other compounds. By optimizing the structure of ionic liquid, reaction conditions and preparation process of catalyst, its catalytic performance can be further improved to meet the needs of different industrial fields. With the further study of the catalytic mechanism of ionic liquid and the continuous improvement of the technology, the application of ionic liquid in catalytic hydrogenation reaction will be more extensive and in-depth. At the same time, combined with the development of new materials and new technologies, ionic liquids are expected to achieve innovative applications in more fields and make greater contributions to green chemistry and sustainable development.
