The present study reports the synthesis of D‐galactose based hydrophobic ionic liquid (IL) and its potential application in the removal of Cd2+ ions from aqueous solution. The synthesized D‐galactose based hydrophobic ionic liquid is insoluble in water and stable at room temperature as a solid. Batch adsorption studies were carried out to investigate the sorption capacity of IL toward Cd2+ ions. The experimental data was analyzed with various isotherm and kinetic models to understand the adsorption process. The Arrhenius activation energy was found to be 12.7 and 22.5 kJ/mol, respectively, for 10 and 30 mg/L of initial metal ion concentration suggesting physisorption of Cd2+ ions on to IL. The thermodynamic parameters suggest that the present process is spontaneous and exothermic in nature. The present IL exhibited superior adsorption capacity toward Cd2+ ions in presence of other co‐cations in aqueous solution. These results suggest that, the synthesized IL can be a superior adsorbent for the removal of Cd2+ ions from aqueous solution. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S139–S145, 2019

A new class of d-xylose derived imidazolium-based chiral ionic liquids were designed and synthesized via simple tuning approaches.

Herein, we report the application of a new class of D-xylose derived chiral ionic liquids (CILs) as chiral catalysts for the enantioselective Michael addition reaction between chalcone and diethylmalonate. These CILs were successfully employed for the same reaction and Michael adducts were obtained in very good yields with moderate enantioselectivity.
