ABSTRACT

Isobaric and isothermal vapor liquid equilibrium (VLE) data are presented for binary systems comprising 1H-pyrrole (pyrolle) with light alcohols. The systems measured include 1H-pyrrole + butan-1-ol at 40 kPa and T = (353.2, 363.2, and 373.2) K; 1H-pyrrole + propan-1-ol at 40 kPa and T = (348.2, 358.2, and 368.2) K; and 1H-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 1H-pyrolle + butan-1-ol and 1H-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.
