摘要：

Vapor-liquid equilibrium data are reported for the ammonia-water system at 60 degree C and the ammonia-water system at 40 to 60 degree C at pressures up to 2. 5 MPa. Isobaric vapor-liquid equilibrium data are reported for the ammonia-methanol-water system at 2. 0 MPa and at 60, 100, and 140 degree C. A new apparatus was developed for these measurements and good agreement with available literature data of Kudo and Toriumi for the ammonia-methanol system could be obtained. Correlation of the data with the Patel-Teja equation of state and van der Waals random mixing rules failed to reproduce the curvature of the P-x diagrams; however, mixing rules based on Wilson's local composition could reproduce the detailed system behavior.
