The study of activity coefficients at infinite dilution for organic solutes and water in 1-butyl-4-methylpyridinium dicyanamide, [B4MPy][DCA] using GLC

The main aim of this paper is to investigate the possibility of using ionic liquid as a solvent for the separation processes, especially for extraction of azeotropic mixtures i.e. aliphatic from aromatic hydrocarbons. The first step in assessing the ability of selective extraction is to determine the selectivity based on measurements of activity coefficients at infinite dilution. In this work new data of the activity coefficients at infinite...
