ABSTRACT
In the present paper, density and speed of sound of binary systems formed by ethanol and two amines (N-methyldiethanolamine and triethanolamine) at several temperatures (15, 20, 25, 30, 35, and 40 C) have been determined. The study of these mixtures has covered its complete composition range. Experimental values of these physical properties have been employed to calculate the isentropic compressibility value
