顺丁烯二酸酐-癸二酸二丁酯二元体系等温气液平衡
Isothermal Vapor-liquid Equilibria for the Binary System Maleic Anhydride+Di-n-butylsebacate
摘要
Abstract
Vapor-liquid equilibrium(VLE) data for maleic anhydride (MAN) and its absorption solvents are important for developing and researching the MAN production process. Isothermal VLE data for MAN and di-n-butylsebacate(DBS) binary system at 413.15, 433.15 and 453.15 K were determined with a modified ebulliometer in this work. Saturated pressure of pure DBS and MAN were measured and their Antoine constants were obtained. The experimental results were correlated and calculated using the NRTL model. The UNIFAC model was also used to predict the VLE data. At the same time, the parameters of the NRTL model for the MAN(l) +DBS(2) binary system were obtained. And the predicted results show a good agreement between the correlated data and the experimental data.关键词
