摘要
基团贡献法是预测化合物物化性质的有效方法,被广泛应用于纯物质及混合体系的物性估算。介绍了基团贡献法对离子液体的密度、黏度、电导率及对CO2和SO2气体吸收的预测。分析表明,通过建立基团贡献法的参数模型,可以定向设计离子液体,推动离子液体在气体吸收方面的工业化应用。对基团贡献法主要优势进行总结,对ILs吸收气体的工业化应用进行了展望。
Group contribution method is an effective method to predict the physicochemical properties of the compounds, and is widely used in the estimation of physical properties of pure substances and mixed system. This paper introduces the applica- tion of group contribution method in the prediction of ionic liquid's density, viscosity, conductivity and CO2, SO2 gas absorp- tion. The analysis shows that, through establishment of group contribution method parameter model, ionic liquids can be direc- tionally designed to promote the industrial application in gas absorption area. The main advantage of group contribution method is summarized and the industrial application trend of ionic liquid for absorbing gas is prospected.
