MARIA MAGDALENA BUDEANU, VASILE DUMITRESCU, SIMONA RADU, ALEXANDRU CAMENITA DENSITIES, VISCOSITIES AND EXCESS PROPERTIES OF BINARY MIXTURES OF 2-METHOXY-2-METHYLPROPANE WITH ISO-PROPANOL Densities (r) and viscosities (h) of the binary systems 2-Methoxy-2-methylpropane with iso-propanol were measured at temperatures (288.15, 293.15, 298.15, 303.15 and 308.15) K and atmospheric pressure, over the whole composition range. The density and viscosity of the solutions were correlated with the temperature with a linear equation, respectively with Guzman’s equation. The excess values of molar volume (VE), viscosity (hE) and molar Gibbs energy (DG*E) were calculated from experimental measurements. The excess functions of the binary systems were fitted to Redlich-Kister equation. Viscosity results were fitted to the equations of Grunberg-Nissan, Heric-Brewer, Jouyban-Acree and McAllister.
