LIQUID-LIQUID EQUILIBRIA OF TERNARY-SYSTEMS OF WATER PLUS ACETONE AND C-5-ALCOHOL AND C-8-ALCOHOL AT 298-K, 303-K AND 308-K

Ternary liquid-liquid phase equilibria (LLE) of water and acetone with 1-octanol, 2-octanol, 1-pentanol and isopentanol (3-methyl-1-butanol) at 298, 303 and 308 K are presented. With the exception of water + acetone + 1-octanol at 303 K, these systems have not been previously investigated at these temperatures. The data are successfully correlated using the NRTL model. The UNIFAC predictive model was also tested with the various group parameter databases
