ABSTRACT

Refractive index and binary vapor-liquid equilibrium (VLE) data for anisole with xylene isomers (p-xylene, m-xylene, o-xylene & ethylbenzene) was measured at a constant pressure of 93.13 kPa by using a dynamic recirculation still. The applicability of the experimental VLE data for process modeling applications was tested with Herington, Van Ness and absolute mean deviation consistency test and the data was found acceptable. The experimental VLE data were correlated using the Wilson, NRTL and UNIQUAC activity coefficient models and binary interactions parameters were estimated using an objective function of minimizing the difference between experimental and model estimated values of vapor phase composition and total pressure. No azeotropic behavior was observed in any of the binary pairs and appears easy to separate using conventional distillation method.
