Abstract: Thermodynamic information about the vapor-liquid equilibria of systems containing water and ethanolamines is needed in the design and optimization of important industrial processes. This knowledge is also useful in the investigation of some phenomena such as the thermal conversion of ethanolamines or their complexation reactions with metals. Physico-chemical investigations involving aqueous solutions of ethanolamines are scarce, and sometimes contradictory, in the literature. It has been stated [1] that the system diethanolamine-water obeys Raoult's law. However, there have been studies [2] indicating departure from ideal behavior for this system. The purpose of this work was to determine the molar excess Gibbs free energies of the systems formed by water and the ethanolamines. © 1980.
