ISOBARIC VAPOR-LIQUID-EQUILIBRIUM OF BINARY-MIXTURES OF 1-BUTANOL PLUS CHLOROBENZENE AND 2-BUTANOL PLUS CHLOROBENZENE AT 20 AND 100 KPA

Isobaric vapor-liquid equilibria were obtained for l-butanol + chlorob enzene and for 2-butanol + chlorobenzene systems at 20 and 100 kPa usi ng a dynamic still. The experimental error in temperature was +/-0.1 K , in pressure +/-0.01 kPa and +/-0.1 kPa for the experiments carried o ut at 20 and 100 kPa, respectively, and in liquid and vapor compositio n +/-0.001. The two systems satisfy the point-to-point thermodynamic c onsistency test. Both systems show a positive deviation from ideality. The data were correlated with the Wilson equation.
