ISOBARIC VAPOR-LIQUID-EQUILIBRIUM OF BINARY-MIXTURES OF 1-PROPANOL PLUS CHLOROBENZENE AND 2-PROPANOL PLUS CHLOROBENZENE

Isobaric vapor-liquid equilibria were obtained for the system 1-propan ol + chlorobenzene at 20 and 100 kPa and for the system 2-propanol + c hlorobenzene at 100 kPa using a dynamic still. The experimental error in temperature was +/-0.1 K, in pressure +/-0.01 kPa and +/-0.1 kPa fo r the experiments carried out at 20 and 100 kPa, respectively, and in the liquid and vapor mole fraction 0.001. The two systems satisfy the point-to-point thermodynamic consistency test. Both systems show a pos itive deviation from ideality. The data were well correlated with the Margules, Van Laar, Wilson, NRTL and UNIQUAC equations. (C) 1997 Elsev ier Science B.V.
