Superbase-derived protic ionic liquids with chelating fluorinated anions
摘要:
Eighteen new protic ionic liquids were synthesized in one step from five organic superbases and five commercially available fluorinated beta-diketones. Physical properties of the ionic liquids, including thermal decomposition temperature were determined. Nine of the ionic liquids were examined as extraction media for La3+, with some very large distribution coefficients obtained. (C) 2011 Elsevier Ltd. All rights reserved.
