Zusammenfassung:A process for absorbing carbon dioxide from a gas stream containing carbon dioxide, including the steps of contacting the gas stream with an aqueous composition including a substituted heteroaromatic compound having a six-membered heteroaromatic ring with from 1 to 3 nitrogen atoms in the heteroaromatic ring and at least one substituent wherein at least one of the substituents is of formula -R1NH2 wherein R1 is selected from C1 to C6 alkylene and ethers of formula -R2-O-R3- wherein R2 and R3 are C1 to C3 alkylene.
