Experimental Study of Liquid-Liquid-Vapor Phase Equilibria Behavior in Gas Solvent + Polar Solute Mixtures

本研究是对常见气体溶剂与极性溶质二元混合物的液气平衡的实验研究，这将有助于我们对复杂分子体系中多相平衡的基本理解。为了评价极低挥发性、极性广泛发散的溶质液相的相对可分离性，还将研究三元混合物的液-液-气区域的详细研究。所获得的数据对于提供包含极性分子的定义良好的混合物的多相平衡数据库，以补充现有的非极性混合物的多相数据具有价值。这项研究还应该为从环境、制造和精炼应用中可能出现的复杂混合物中分离某些分子类型物种的可能新方法提供相当大的见解。

This research is an experimental study of the liquid-vapor equilibria of selected binary mixtures of common gas solvents with polar solutes, which will contribute to our fundamental understanding of multiphase equilibria in complex molecular systems. Detailed studies of the liquid-liquid-vapor regions of ternary mixtures will also be studied in order to evaluate the relative separabilities of the liquid phases of very low volatility solutes with widely divergent polarities. The data to be obtained are of value for providing a database of multiphase equilibria on well-defined mixtures containing polar molecules to complement existing multiphase data on nonpolar mixtures. This study should also provide considerable insight into possible new methods to separate certain molecular types of species from complex mixtures that might occur in environmental, manufacturing, and refining applications.
