Data supporting protic ionic liquids with low viscosity for efficient and reversible capture of carbon dioxide
The data presented in this article affords insight into the synthesis, characterization, and CO2 absorption performance of three low viscous protic ionic liquids (PIL), tetramethylgunidinium imidazole ([TMGH][Im]), tetramethylgunidinium pyrrole ([TMGH][Pyrr]) and tetramethylgunidinium phenol ([TMGH][PhO]). The density and viscosity of PILs were measured using density meter and viscometer. The experimental setup for CO2 absorption was followed weighing methods. in-situ FTIR and theoretical calculations were used to analyze the interaction between ILs or IL-H2O system and CO2.
