摘要
Abstract
The VLE data of acetone-isoproponal,acetone-water,isoproponal-water and acetone-isoproponal-water were determined with single stage vapor-liquid equilibrium pot at atmospheric pressure.The experimental data of binary systems were verified by Herington method to judge whether it is satisfied for the thermodynamics consistency.The data of binary systems were corrected with Wilson,NRTL,UNIQUAC models by minimum variance method.Using the correlated three model parameters of binary systems to calculate the experimental VLE data of ternary system.Compared with the experimental data,the results show that the relative deviation of experiment and calculation is less than 5％.It means that the experimental data are consistent with the calculation results.The results provide a basis for the separation of acetone-isoproponal-water system.关键词
