ABSTRACT

Liquid-liquid equilibrium data is widely used in many industrial sectors. For this reason, it is important to know thermodynamics binary mixtures data to better understand molecular interactions between those components. This work reports experimental density ( a) and speed of sound (poundso) data for 2-hydroxyethanolamine acetate + 1-propanol, 2-hydroxyethanolamine acetate + 2-propanol, 2- hydroxydiethanolamine acetate + 1-propanol and 2-hydroxydiethanolamine acetate + 2-propanol binary mixtures, over a wide composition range, between 293.15 and 323.15 K, and at atmospheric pressure (101.3 kPa). For that, a vibrating tube densitometer was used to perform density and speed of sound experimental measurements. From these data, important derivative properties have been calculated, such as: isentropic compressibility (poundseS), apparent molar isentropic compressibility (poundseo), excess molar volumes (.... ), and apparent molar volume (VO).
