The application of ionic liquids in the field of extractive distillation in recent years is reviewed. Introduced in recent years, the application of experimental and model predictive screening ionic liquid extractant research results, including experimental methods include gas-liquid equilibrium method and infinite dilution activity coefficient method, the model prediction method mainly involves Wilson model, NRTL model, UNIQUAC Model, COSMO-RS model and so on. Our group conducted a more in-depth study on the application of ionic liquids as extractants in the extractive distillation process. The defects of ionic liquid in practical production and application and its development potential as a green solvent were analyzed.
