Carbon Dioxide Solubilities in Decanoic Acid-Based Hydrophobic Deep Eutectic Solvents

[Image: see text] The solubility of CO(2) in hydrophobic deep eutectic solvents (DESs) has been measured for the first time. Six different hydrophobic DESs are studied in the temperature range from 298 to 323 K and at CO(2) pressures up to 2 MPa. The results are evaluated by comparing the solubility...

description [Image: see text] The solubility of CO(2) in hydrophobic deep eutectic solvents (DESs) has been measured for the first time. Six different hydrophobic DESs are studied in the temperature range from 298 to 323 K and at CO(2) pressures up to 2 MPa. The results are evaluated by comparing the solubility data with existing hydrophilic DESs and currently applied physical solvents and fluorinated ionic liquids. The DESs are prepared by mixing decanoic acid with a quaternary ammonium salt with different halide anions and alkyl chain lengths. The measured CO(2) solubilities are similar to those found in renowned fluorinated ILs, while the heats of CO(2) absorption are in the range of nonpolar solvents. The presented DESs show good potential to be used as CO(2) capture agents.
