Volumetric properties of the isopropanolamine-water mixture at atmospheric pressure from 283.15 to 353.15 K

Densities of the isopropanolamine-water binary mixture system were measured over the whole range of compositions at temperatures from 283.15 to 353.15 K using an Anton Paar digital vibrating glass tube densimeter. The density of this system has been found an increasing function of the isopropanolamine composition. Excess molar volume data, calculated from the measured experimental densities, have been correlated using the Redlich-Kister equation. Parameters for the Redlich-Kister equation have been adjusted. Partial molar volumes at infinite dilution have been calculated for each component. (C) 2005 Elsevier B.V. All rights reserved.
