摘要：

Silylamine reversible ionic liquids were designed to achieve specific physical properties in order to address effective CO2 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 CO2 (chemisorption). The RevILs can further capture additional CO2 through physical absorption (physisorption). The effects of changes in structure on (1) the CO2 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 CO2 capture process, and (4) the ability to recycle the solvents systems are reported.
