摘要
UNIFAC基团贡献法是推算组分活度系数应用最广泛的模型之一。介绍了UNIFAC基团贡献法的研究进展,分析了UNIFAC模型在气液平衡(气体溶解度、纯组分的蒸汽压、典型气液平衡预测)、液液平衡(液体混合物的表面张力、萃取精馏体系、聚合物溶液粘度的推算、典型液液平衡预测)、固液平衡(同分异构体的平衡体系、固体溶解度的计算)体系的应用领域及其局限性,并针对UNIFAC基团贡献法存在的问题,提出UNIFAC基团贡献法的研究方向和具体的研究内容。
UNIFAC Group Contribution Method is one of the most extensive models for applications to calculate the component activity coefficient. This text introduces the progress of research, analyzes the applications and limits of UNIFAC model in vaporiquid equilibrium （solubility of gases, vapor pressure of pure component, typical prediction of vapor liquid equilibrium）, liquid-liquid equilibrium （surface tension of fluid mixture, system of extraction and rectification, typical prediction of liquid-liquid equilibrium）, solid-liquid equilibrium （equilibrium of isomer, solubility of solid）and other systems. And to resolve these questions, it also makes a prospect of the trend and specific contents for the study of UNIFAC Group Contribution Method.
