EXCESS GIBBS FREE-ENERGY, ENTHALPY, AND VOLUME AND VISCOSITY OF ACETONE METHYL CELLOSOLVE MIXTURES

Isothermal vapor-liquid equilibrium data at 70, 60, and 48.2 °C, and isobaric data at 1 atm pressure are reported for the acetone-methyl cellosolve system. The molar excess enthalpies at 48.2 °C and excess volume at 40 °C are measured In an isothermal phase change calorimeter and a glass dllatometer, respectively. The kinematic viscosity data at 25, 30, 35, 40, and 48.2 °C are obtained by using an Ostwald viscometer. The VLE data are corrected for vapor-phase nonideallty and tested for thermodynamic consistency. The kinematic viscosity data are correlated by McAllister and excess function models. © 1979, American Chemical Society. All rights reserved.
