Physico‐chemical absorption data of CO 2 in three industrially important hybrid (physical + chemical) solvents were obtained in the temperature range of 0‐25°C and at a constant partial pressure of the gas of 95.59 kPa. The systems studied were N‐methyl 2‐pyrrolidone, sulfolane and methanol with a minute quantity of 40% aqueous dimethyl amine (aq.DMA). The CO 2 uptake increased by two to three fold as compared to that of the pure physical solvents, and decreased with increases in temperature. Absorption also increased with the amount of aq.DMA added.
