Base-stable ionic liquids for extraction of metal ions from alkaline aqueous solutions
Book - Dissertation
Ionic liquids are solvents that consist entirely of ions. They have unique properties such as a very low vapor pressure, an intrinsic electric conductivity and a good thermal stability. They can act as solvents for many types of organic and inorganic compounds. Ionic liquids have applications ranging from solvents for catalytic organic reactions, over solvents for liquid-liquid extraction to electrolytes for batteries. Although ionic liquids are very stable against strong acids, most ionic liquids have a poor stability towards strong bases. This project is about the design of a new class of base-stable ionic liquids, derived from highly substituted 1,2,3-triazoles. The stability of these new triazolium ionic liquids against different types of strong bases is tested. Water-immiscible triazolium ionic liquids are used as organic phase for solvent extraction of metal ions from alkaline aqueous feed solutions.
