摘　　要：The isobaric vapor-liquid equilibrium data of butanone(1)-N, N-dimethylformamide (DMF)(2) at 100.92kPa, 93.32kPa, and 79.99kPa and of toluene(1)-DMF(2) at 100.92kPa were measured using a modified Rose-Williams still. The above data met the thermodynamic consistency test and were correlated with the Wilson,NRTL, and UNIQUAC equations. These data can be used in the analysis and design of the process that involves separating DMF from butanone and toluene in the leather synthesis industry.The isobaric vapor-liquid equilibrium data of butanone(1)-N, N-dimethylformamide (DMF)(2) at 100.92kPa, 93.32kPa, and 79.99kPa and of toluene(1)-DMF(2) at 100.92kPa were measured using a modified Rose-Williams still.
