Abstract

Environment regulations and a strict legal framework motivate scientists and researchers to develop clean technologies for sustainable development. Researchers amplify their efforts to convert separation processes like extraction and distillation into clean technologies. The knowledge of thermodynamic properties like equilibrium data and activity coefficient at infinite dilution is required for adequate separation. Liquid–liquid equilibrium (LLE) data help in the selection of solvent for the selective separation of the solute component. In addition to this economic aspect, clean technology also considers the ecological aspect. Since the past few decades, eco-friendly solvents like ionic liquids (ILs) have been considered as a better replacement for conventional volatile solvents (Brennecke & Maginn, 2001; Welton, 1999). The rate of publication in the open literature has been rising at a greater rate for years. A total of 12,400 papers have been published since 2007 against 7,400 published between 1990 and March 2007. These data show the increase in new applications of ILs (Martins et al., 2014).
