Abstract

This report, describes the concept of multifuncionalized-carboxylate-based Task-Specific Ionic Liquid (TSIL) in combination with controlled quantity of water, in order to capture CO₂. Different examples of TSILs were prepared centred on a acid-base reaction between formic acid, di-, tri-, terra- and multifunctionalized carboxylic acids in combination with the proper number of equivalents of an organic superbase, 1, 8-Diazabicyclo [5.4.0]undec-7-ene (DBU). The TSILs preparation method sustainability is centred on the atom economy of the reaction and use of ethanol as solvent. The use of one of these Ionic Liquids is highlighted in this work, namely the DBU-based salt of Aspartic acid: [DBUH⁺]₂[Asp²⁺]. An aqueous solution of this salt was prepared and tested for carbon dioxide capture. CO₂ uptake in wt% was obtained and evaluation of reactional mixture by NMR and FTIR techniques was carried out.
