Abstract
Ionic liquids, as a novel class of green solvents, exhibit extensive application prospects in pharmaceutical synthesis due to their unique physicochemical properties. This study investigates the application of ionic liquid-based extraction separation technology in pharmaceutical synthesis to enhance both the efficiency and quality of drug production. By systematically examining the selective extraction capabilities of different types of ionic liquids on target drug molecules, it was found that ionic liquids with specific structures significantly improve the separation efficiency of the desired products. The experimental conditions were optimized using response surface methodology, determining the optimal process parameters and achieving effective separation of multiple pharmaceutical intermediates. Compared with traditional organic solvents, this method demonstrates higher selectivity and yield while reducing environmental pollution risks. The results indicate that ionic liquids as extraction media not only effectively avoid safety issues associated with conventional solvents but also markedly improve product purity. Through an in-depth analysis of the mechanism by which ionic liquids function in the reaction system, their unique advantages in the pharmaceutical synthesis process were revealed. Innovatively applying ionic liquids in the post-processing stage of pharmaceutical synthesis provides new insights for developing efficient and environmentally friendly drug preparation processes, potentially advancing green pharmaceutical technology. The research findings lay a theoretical foundation for the practical application of ionic liquids in the pharmaceutical industry, showcasing promising potential for industrial application.
