| Abstract: | Surface tensions of diethanolamine(DEA)-water mixtures are the basic data for the CO2 absorption technologies by alkanolamine aqueous solutions.The surface tensions of DEA-water mixtures from 25 to 82 ℃ were measured by using an automatic tension-meter.The experimental data were correlated with an empirical equation and the agreement was satisfactory.Using the correlated equations,thermodynamic properties like surface enthalpy and surface entropy were determined and their temperature and concentration dependence was obtained. |
