Vapor liquid equilibria (VLE) for following systems were determined by use of a flow still and a static pressurized still: ① 2-methylbutane(1)methanol(2)(55.0℃); ② 2-methylbutane(1)tertamyl methyl ether (TAME)(2)(15.0℃,22.0℃,55.0℃); ③ 2-methylbutane(1)methanol(2)TAME(3)(55.0℃,65.0℃,80.0℃). Data for all binary systems passed the thermodynamic consistency check. Wilson、 NRTL and UNIQUAC models were used to correlate the VLE data determined and their model parameters were obtained. Results show that the NRTL model is the best. The total average vapor composition deviations are 0.0048 for correlation of binary systems and 0.0075 for prediction of ternary system.
