摘要
低碳醇共沸体系广泛存在于化工、制药和食品等各个工业领域,因此迫切需要开发高效、经济的分离技术来满足日益增长的市场需求。萃取作为分离共沸混合物的一种经济有效的方法,在很大程度上取决于萃取剂的选择。由于离子液体(IL)的独特物理性质和萃取过程的重要性,越来越多的研究人员开始利用离子液体作为萃取剂。本文回顾了离子液体用于分离低碳酒精体系的两相行为研究的最新进展,详细介绍了分子模拟在相平衡研究中的应用。此外,本文还介绍了用于低碳醇的惰性醚的液-液萃取分离模型,发现 NRTL 模型在拟合过程中表现良好。最后,论文探讨了以 ILs 为萃取剂分离低碳醇体系的机理分析、实验研究和模拟研究进展。
Multiscale analysis of the phase behavior of azeotropic systems containing low-carbon alcohols with ILs as extractants
Low-carbon alcohol azeotropic systems are widely present in various industrial fields such as chemicals, pharmaceuticals, and food, creating an urgent need for the development of efficient and cost-effective separation technologies to meet the growing market demand. Extraction, as an economical and effective method for separating azeotropic mixtures, relies heavily on the choice of extracting agents. Due to the unique physical properties of ionic liquid (ILs) and the importance of the extraction process, an increasing number of researchers are utilizing ILs as extracting agents. This paper reviews recent advances in the two-phase behavior studies of ILs for separating low-carbon alcohol systems, detailing the application of molecular simulation in phase equilibrium research. Additionally, it describes the liquid-liquid extraction separation model of ILs for low-carbon alcohols, revealing that the NRTL model performs well during the fitting process. Finally, the paper explores the mechanism analysis, experimental studies, and simulation research progress of using ILs as extracting agents for the separation of low-carbon alcohol systems.
