ABSTRACT
In this paper, we present atmospheric pressure liquid densities for binary mixtures of n-methyldiethanolamine + water over the entire composition range at temperatures between 263.15 and 363.15 K. We measure the liquid densities using a vibrating tube densimeter and use them to produce a correlation for excess molar volumes based upon a Redlich-Kister equation. The excess volumes exhibit negative deviations from ideality at all the investigated temperatures and become less negative with increasing temperature.
