Isobaric Vapor-Liquid Equilibrium for Thiophene-Pyridine-Dimethyl Sulfoxide System
摘要
Abstract
Isobaric vapor-liquid equilibrium (VLE) data of thiophene-pyridine-dimethyl sulfoxide ternary system and three constituent binary systems with different liquid phase composition were measured by using a pump-ebullionmeter. The three binary systems were correlated with the Wilson, NRTL, Margules and van Laar models, respectively. The VLE data correlation results of the three binary systems show that the NRTL model is much better than the other models, and its average absolute values of temperature deviation of above three binary systems are 0.13 K, 0.27 K and 0.39 K, respectively. The VLE data of the ternary system were evaluated by respectively using the different parameters obtained from above three binary systems with the four different models, and then from the evaluation of the VLE data, the vapor-phase compositions y and the calculated bubble point were obtained. The thermodynamic consistency of the VLE data were checked by means of the Herington test for the binary systems and the McDermott-Ellis test for the ternary system, respectively, and the results show that the VLE data of these systems strictly satisfy the thermodynamic consistency.关键词
