The resulted beta-amino acid-TSILs were evaluated for CO2 scrubbing under ambient pressures and expected to mimic the reactivity of the alkanolamine system. Depending on the anion structure, the number of amino group, and type of solvent (water or ethylene glycol), 0.6-0.9mol of CO2 was captured per mol of TSIL at 0.1MPa and at 313K. FT-IR and 13C NMR spectroscopy studies indicated the formation of ammonium carbamate and HCO3- species when atmospheric CO2 was bubbled through a solution containing 30wt.% of amino acid-TSIL. © 2012 Elsevier B.V.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]13C NMR spectroscopy,Ammonium carbamates,Capture,Hydrolysis reaction,Michael additions,Mild reaction conditions,Task-specific ionic liquids,Tetrabutylammonium hydroxides[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Capture,Carbon dioxide,Hydrolysis,Michael addition,Task specific ionic liquids[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.cej.2012.01.021[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
