ABSTRACT
Density and speed of sound of ternary systems formed by water + ethanol + N-methyldiethanolamine or triethanolamine at a fixed volume ratio of ethanol to water of 50 % (ethanol mole fraction of 0.2336 corresponding to water + ethanol mixture) were determined at several temperatures (15, 20, 25, 30, 35, 40, 45, and 50 deg C). Experimental values of these physical properties have been employed to calculate isentropic compressibility value.
