DENSITIES, EXCESS MOLAR VOLUMES, AND PARTIAL MOLAR VOLUMES FOR BINARY-MIXTURES OF WATER WITH MONOETHANOLAMINE, DIETHANOLAMINE, AND TRIETHANOLAMINE FROM 25-DEGREES-C TO 80-DEGREES-C

We have measured densities of binary mixtures of water with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) over the full range of compositions and over the temperature range from 25 to 80-degrees-C. Results of these measurements have been used in calculating excess molar volumes and partial molar volumes. Knowledge of the volumetric properties of these mixtures is useful in connection with industrial treatment of acidic gases, derived excess molar volumes and partial molar volumes can be used as a basis for understanding some of the molecular interactions in water-organic mixtures.
