M. Iglesias et al., Vapor-liquid equilibria for the ternary system acetone plus methanol plus water at 101.325 kPa, J CHEM EN D, 44(4), 1999, pp. 661-665
The vapor-liquid equilibrium at 101.325 kPa has been measured for the terna
ry system acetone + methanol + water in an equilibrium still with circulati
on of phases. Satisfactory results were obtained for the prediction of acti
vity coefficients and the equilibrium compositions with group contribution
models (ASOG, UNIFAC, UNIFAC-Dortmund, and UNIFAC-Lyngby). Small standard d
eviations of vapor molar fraction and temperature were calculated. Azeotrop
ic behavior was observed only in the acetone + methanol mixture. The correl
ation parameters for the Tamir-Wisniak and UNIQUAC equations were presented
.
