ABSTRACT

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 (x1 = 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.
