Popis: Experimental isobaric vapor−liquid−liquid and vapor−liquid equilibrium data for the ternary system water (1) −cyclohexane (2) −isooctane (3) and the quaternary system water (1) −ethanol (2) −cyclohexane (3) −isooctane (4) were measured at 101.3 kPa. An all-glass, dynamic recirculating still equipped with an ultrasonic homogenizer was used to determine the VLLE. The results obtained show that the system does not present quaternary azeotropes. The point-by-point method by Wisniak for testing the thermodynamic consistency of isobaric measurements was used to test the equilibrium data.
