Acetylcholine-based deep eutectic solvents for highly efficient SO2 absorption, selective separation from CO2 and their mechanism

Improved Reversible and Selective SO2 Absorption by a Stable Phosphonium Carboxylate Ionic Liquid

“…Our approach differs from other models previously reported to describe the isothermic SO 2 absorption in ILs that did not take into account the extent of the reaction chemical reaction. Thus the calculated Henry’s law constants were often inaccurate since the composition of the solution significantly changes as the chemisorption of the gas proceeds. , Other models based on 1:1 or 2:1 stoichiometry have been suggested, but when tested with our experimental data, non-physically sound results were calculated for the 2:1 reaction, further confirming the mechanism assumed herein.…”

Starch esterification using deep eutectic solvents as chaotropic agents and reaction promoters

“…It is noteworthy to mention that both compounds have been successfully used to produce eutectic solvents themselves, and even applied in the valorization of biomass and the capture of emission gases. 82–84 Indeed, the recovered samples of acetylcholine : urea 3 : 1 remained liquid at room temperature. Their potential as green solvent in esterification reactions warrants further experimentation.…”
