Solubilities of carbon dioxide in 2-methoxyethyl acetate, 1-methoxy-2-propyl acetate and 3-methoxybutyl acetate

摘要: Abstract The solubilities of CO2 in 2-methoxyethyl acetate, 1-methoxy-2-propyl and 3-methoxybutyl acetate were measured by isothermal synthesis method under pressures up to 1.2 MPa at temperatures ranging from (293.15 333.15) K. Henry’s constant was calculated based on experimental data regression. found increase with decreased temperature increased the methyl group molecular structure absorbent. volumetric solubility selected absorbents T = 298.15 K compared those commercial common solvents. 3-Methoxybutyl showed best performance mole fraction, behaved fraction. Based constant, thermodynamic properties such as Gibbs free energy solution, enthalpy absorption entropy solution determined. These are very essential for designing an process.
