Vapor liquid equilibrium for the binary systems 2-methylpentane+2-butanol at 329.2 K and n-hexane+2-butanol at 329.2 and 363.2 K with a static apparatus
A static total pressure apparatus was build. Isothermal vapour-liquid equilibrium of two binary systems, 2-methylpentane + 2-butanol at 329.2 K and n-hexane + 2-butanol at 329.2 K and 363.2 K were measured. The results of the 2-methylpentane + 2-butanol measurements were compared with earlier measurements made with a recirculation still and good agreement was found. The ability of estimation methods (UNIFAC and modified UNIEFAC Dortmund) to predict the measured data was tested. The capability of the original UNIFAC to predict the behaviour of the systems measured was worse than the performance of the modified UNIFAC Dortmund.
