Fourteen cholinium-amino acid based room temperature ionic liquids were prepared using a cleaner synthetic method. Chemicophysical properties were well correlated with the wide range of amino acid chemical structures.

liquids (ChAAILs) were much environmentally friendly. Therefore, the ChAAILs/salt aqueous two-phase systems (ATPSs) were developed for the chiral resolution of valine enantiomers in this study. The copper complexes were prepared by ChAAILs and Cu(Ac)2, which can be used as both the phase-forming components and the chiralselectors. A series of factors affecting the enantioseparation result were investigated
