Li, Yun published the artcileSolubility Measurement and Thermodynamic Properties Calculation for Several CO2 + Ether Absorbent Systems, HPLC of Formula: 143-24-8, the main research area is solubility thermodn property carbon dioxide ether absorbent system.
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.
Journal of Chemical & Engineering Data published new progress about Absorption. 143-24-8 belongs to class ethers-buliding-blocks, name is 2,5,8,11,14-Pentaoxapentadecane, and the molecular formula is C10H22O5, HPLC of Formula: 143-24-8.
