Vapor-Liquid Equilibrium Data for Binary Systems of 1H-Pyrrole with Butan-1-ol, Propan-1-ol, or Pentan-1-ol

摘要

Isobaric and isothermal vapor-liquid equilibrium (VLE) data are presented for binary systems comprising lH-pyrrole (pyrolle) with light alcohols. The systems measured include lH-pyrrole + butan-1-ol at 40 kPa and T = (3S3.2, 363.2, and 373.2) K; lH-pyrrole + propan-1-ol at 40 kPa and T = (348.2, 358.2, and 368.2) K; and lH-pyrrole + pentan-1-ol at 40 kPa and T = (353.2, 363.2, and 373.2) K. Measurements were undertaken on a low-pressure dynamic still, with analysis of the equilibrium samples by gas chromatography. The IH-pyrolle + butan-1-ol and lH-pyrolle + pentan-1-ol systems exhibited azeotropic behavior for both the isobaric and the isothermal measurements. The measured data were. modeled using the Wilson and nonrandom two-liquid (NRTL) excess Gibbs energy models, with both models correlating the data well.
