摘要：

Deep eutectic solvents are based upon environmentally benign moieties and have the potential to capture CO2 from flue gases. In this study, guanidine carbonate, malic acid, ethylene glycol, arginine and water were mixed in certain molar ratios to produce eutectic solvents. Their viscosities were determined in a temperature range of 303.2 - 330.2 K, while Henry's law constants of CO2 for these solvents were obtained at 313.2 K. The results have been compared with some other water-lean solvents and showed a compromise exists between the viscosity and CO2 solubility of eutectic based solvents for potential use in carbon capture applications.
