ABSTRACT

Vapor-liquid equilibrium (VLE) data for cis-2-butene + methanol, + 2-propanol, + 2-butanol, and + 2-methyl-2-propanol were measured at 364.5 K with a static total pressure apparatus. Measured pTz (pressure-temperature-total composition) data were reduced to liquid- and vapor-phase compositions using Barker s method. An azeotropic point was found for cis-2-butene + methanol (x1 ) 0.847; T ) 364.52 K; p ) 1303.8 kPa). Wilson parameters were calculated; the results were compared with predictive UNIFAC and UNIFAC-Dortmund models; and an error analysis was made.
