What is Butanol Recovery from Aqueous Solution Into Ionic Liquids by Liquid–liquid Extraction about?

Biobutanol has currently attracted considerable attention as an alternative biofuel to the petroleumderived fuel due to several advantages including high energy content, low water absorption and easy application to the existing gasoline infrastructure. However, its production has still faced many obstacles to overcome including lack of energy-efficient butanol separation process from fermentation broth. To solve this issue, the extraction behavior of butanol from aqueous media into a variety of imidazoliumbased ionic liquids (ILs) was investigated by liquid-liquid extraction. To understand the effect of ILs properties, the solvent characteristics of ILs such as mutual solubility of feed solvent (water) and extraction solvent (IL), distribution coefficient of butanol between water and IL, selectivity, and extraction efficiency were correlated with hydrophobicity and polarity of ILs. The butanol distribution between ILs and water strongly depends on the hydrophobicity of anions of ILs followed by the hydrophobicity of cations of ILs. On the other hand, butanol extraction efficiency and selectivity depend on the polarity of ILs. Considering extraction efficiency and selectivity, [Tf 2
