摘要
本文讨论了由于环丁砜(SF)与水的物性本质差异导致了甲基二乙醇胺(MDEA)在环丁砜水中溶液中的pK_a值低于在水中的pK_a,使得H_2S、CO_2在环丁砜——甲基二乙醇胺水溶液中的溶解度和在MDEA水溶液中有明显不同。
In this paper, it is discussed that because of the intrinsic difference between the physical properties of sulfolance(SF)and water, the pK. of MDEA in SF-H_2O solution is lower than the pK. of MDEA in water to make the solubilities of H_2S and CO_2in SF-MDEA-H_2O solution are evidently different from that in aqueous MDEA solution.
