ABSTRACT
Two vibrating tube densimeters have been used to measure the densities of two hybrid solvents: water + diethanolamine + methanol and water + N-methyldiethanolamine + methanol in the temperature range (283-353) K. The alkanolamines and methanol contents are respectively between 20 and 50 and between 20 and 60 mass percent. The experimental results have been correlated using the Redlich-Kister equation. A set of parameters for the Redlich-Kister equation has been determined using the densities of pure compounds and of binary systems available in the literature. The methodology has been extended to density calculations dealing with hybrid solvents.
