Screening of ionic liquids as extractant for 1-butanol extraction from dilute solution

Extraction of 1-butanol from dilute solution is one of the most popular means for bio-butanol recovery due to its low energy consumption and easy operation. However, the problems of low efficiency, solvent loss, extractant toxicity and etc. existed and needed to be solved by finding new extractant. Ionic liquids (ILs) as new material have been the potential extractants due to their special thermo-physical properties of negligible vapor pressure,...
