Vapor-liquid equilibrium data for binary systems of 1H-Pyrrole with Butan-1-ol, Propan-1-ol, or Pentan-1-ol. Journal of Chemical and Engineering Data. 57(9): 2520-2527. doi:10.1021/je30041940021-95681520-5134 (Online)isidoc: 003SGhttps://hdl.handle.net/10321/4690Isobaric 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. © 2012 American Chemical Society.8 pen0904 Chemical EngineeringChemical EngineeringArticle2023-03-2710.1021/je3004194
