摘要: Abstract Isobaric vapor–liquid equilibrium (VLE) data for the quaternary system sec-butyl alcohol + sec-butyl acetate + N, N-dimethyl formamide (DMF) + dimethyl sulfoxide (DMSO) and constituent binary DMF + DMSO were determined at 101.3 kPa with a modified Othmer still. The measured experimental of systems certified to be thermodynamically consistent according Van Ness method. And correlated by Wilson, NRTL UNIQUAC activity coefficient models. rest interaction parameters have been obtained in our previous work. Then, predicted models parameters. results show that three yield good prediction systems. But model performed better than other two predicting VLE system.
