vapor-liquid equilibrium for the systems trans-2-butene plus methanol, plus 1-propanol,plus 2-propanol, plus 2-butanol, and plus 2-methyl-2-propanol at 364.5 K

Vapor-liquid equilibrium (VLE) data for trans-2-butene + methanol, + 1-propanol, + 2-propanol, + 2-butanol, and + 2-methyl-2-propanol were measured at 364.5 K with a static total pressure apparatus. Measured p-T-z (pressure-temperature-total composition) data were reduced to liquid and vapor phase compositions using Barker's method. An azeotropic point was found for trans-2-butene + methanol (x(1) = 0.854; T = 364.52; p = 1385.1 kPa). Wilson model parameters were calculated. The fitted Legendre polynomial was compared against predictive UNIFAC and UNIFAC-Dortmund models, and an error analysis was made.
