چکیده انگلیسی
The solubilities of CO2 in 2-methoxyethyl acetate, 1-methoxy-2-propyl acetate, and 3-methoxybutyl acetate were measured by isothermal synthesis method under pressures up to 1.2Â MPa and at temperatures ranging from (293.15 to 333.15)Â K. Henry's constant was calculated based on experimental data regression. The solubilities of CO2 were found to increase with decreased temperature and increased the methyl group to the molecular structure of the absorbent. Henry's constant and volumetric solubility of selected absorbents at TÂ =Â 298.15Â K were compared with those of commercial absorbents and common solvents. 3-Methoxybutyl acetate showed the best performance by mole fraction, and 2-methoxyethyl acetate behaved the best by volumetric fraction. Based on Henry's constant, thermodynamic properties such as Gibbs free energy of solution, enthalpy of solution, and absorption entropy of solution were determined. These properties are very essential for designing an absorption process.
