摘要：
The constant-volume method is used to determine the solubility of CO2 in methanol, ethanol, n-propanol, n-butanol, n-propanol, ethylene glycol, propylene glycol, acetone, 2-butanone, ethylene glycol monomethyl ether, and ethylene glycol monoethyl ether under the pressure of 6 MPa and the temperature variations from (288.15 to 318.15) Kin this paper. It is found by contrast that ketones have a greater ability to dissolve CO2 than alcohols, ethers, and glycols, which also indicate that both the carbonyl group and the ether bond in solvents can promote the CO2 absorption, but hydroxyl group will inhibit the CO2 absorption.
