Six phys. absorbents with the ether groups were selected for CO2 absorption: tetraethylene glycol di-Me ether (TEGDME), diethylene glycol monohexyl ether, 2-butoxyethyl ether, triethylene glycol monobutyl ether, ethylene glycol di-Bu ether, and dipropylene glycol di-Me ether (DPGDME). CO2 solubilities in these absorbents were measured at 273.15 and 283.15 K and 0-1.2 MPa. Henry’s constants of these CO2 + ether absorbent systems were calculated and analyzed at 273.15 K. The ether group is found more powerful than the methylene group, and the Et group is more effective than the hydroxyl group to improve the absorption ability of the absorbents. A lower temperature tends to facilitate the absorption process by increasing the absorption ability. Henry’s constants and mass solubilities of the ether absorbents were compared with those of the ionic liquids, common solvents, and other absorbents. TEGDME and DPGDME are potential absorbents according to the evaluation in both mole and mass fraction. The thermodn. properties, such as entropy, enthalpy, and Gibbs free energy of solution, for CO2 + the ether absorbent systems were calculated and discussed for potential development of corresponding CO2 capture processes. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol
