In this chapter, a solvent selection methodology for extractive distillation processes is applied to identify promising ionic liquid (IL) solvents for the following separation cases: methylcyclohexane/toluene, 1-hexene/n-hexane and ethanol/water. Thermodynamic and phase stability analysis are done in order to understand the strong interactions between the solutes and the ionic liquids (solvents...

Mechanistic analysis of the reaction between elemental sulfur or selenium and 1,3-dialkylimidazolium acetate ionic liquids, in the absence of an external base or solvent, affords evidence for the equilibrium presence of carbene species in these ionic liquids. It demonstrates the potential to control, through anion selection, the concentration of carbene in stable ionic liquids.

A systematic and quantitative methodology for synthesis of gas separation networks is being developed to allow generation of effective and economic separation schemes. Synthesis includes selection of appropriate separation methods, e.g. absorption, lowtemperature separation processes and membrane permeation. In the screening step of the methodology, a quick assessment of alternative separation ...
