ABSTRACT

Density, speed of sound, viscosity, and surface tension of the binary mixtures N-ethyl-2-pyrrolidone (EP) + ethanolamine (MEA) (or diethanolamine (DEA) or triethanolamine (TEA)) were measured at different temperatures from (293.15 to 323.15) K over the entire range of concentrations. The excess molar volumes and isentropic compressibility deviations were calculated. Moreover, the excess molar volumes were fitted using a Redlich Kister equation, and the surface tension data were fitted by the Connors Wright model.
