Abstract
- Silylamine reversible ionic liquids were designed to achieve specific physical properties in order to address effective CO<subscript>2</subscript> capture. The reversible ionic liquid systems reported herein represent a class of switchable solvents where a relatively non-polar silylamine (molecular liquid) is reversibly transformed to a reversible ionic liquid (RevIL) by reaction with CO<subscript>2</subscript> (chemisorption). The RevILs can further capture additional CO<subscript>2</subscript> through physical absorption (physisorption). The effects of changes in structure on (1) the CO<subscript>2</subscript> capture capacity (chemisorption and physisorption), (2) the viscosity of the solvent systems at partial and total conversion to the ionic liquid state, (3) the energy required for reversing the CO<subscript>2</subscript> capture process, and (4) the ability to recycle the solvents systems are reported.
