Several (water + alkanolamine) systems are used for removal of acidic gases such as carbon dioxide and hydrogen sulfide from gas streams in the natural gas and petroleum industries and are of increasing importance in treating streams in the chemical production industries. The authors have made calorimetric measurements of enthalpies of mixing of (water + monoethanolamine), (water + diethanolamine), and (water + triethanolamine) at T = 298.15 K and of (water + methyldiethanolamine) at T = 298.15 and 313.15 K. Results of these measurements have been used in some thermodynamic calculations to illustrate general principals that are applicable to many systems of mixed liquids.
