Zhang, Kai published the artcileEfficient and Reversible Absorption of CO2 by Functional Deep Eutectic Solvents, Formula: C6H20Cl2N4, the publication is Energy & Fuels (2018), 32(7), 7727-7733, database is CAplus.
Extremely low-volatility functional deep eutectic solvents (DESs), based on ethylene glycol (EG) and diethylene glycol (DG) as hydrogen-bond donor and the ammonium salts obtained from triethylenetetramine (TETA) and HCl at different mole ratios as hydrogen-bond acceptor, were designed and used to capture CO2. All of the designed DESs can efficiently capture CO2 even at low partial pressures. CO2 absorption capacity of [TETA]Cl-EG DES with n[TETA]Cl/nEG 1:3 is high up to 17.5 wt % (1.456 mol CO2/mol [TETA]Cl) at 40 ¡ãC and 1 atm. CO2 absorption capacity decreases with increasing temperature and decreasing CO2 partial pressure. Regeneration experiments show that CO2 absorption capacities in [TETA]Cl-EG DES and [TETA]Cl-DG DES do not vary after five absorption/desorption cycles. It is found that EG or DG can increase the absorption capacity via activating -NH- or -NH2 on [TETA]Cl and enhance the basicity of DESs. In addition, CO2 absorption mechanism in [TETA]Cl-EG DES based on the change of its viscosity during absorption and FTIR anal. indicates that there is a chem. interaction between CO2 and [TETA]Cl, and the stoichiometry for the reversible absorption is 1.5 mols. of CO2 per [TETA]Cl-EG DES mol.
