ABSTRACT
An automated total pressure measurement apparatus was used to measure PTz data that was regressed into PTxy data using the method of Barker (1953). The isothermal vapour liquid equilibrium measurements were carried out for the five binary systems 2-methylpropane + methanol, +ethanol, +2-propanol, +2-butanol and +2-methyl-2-propanol at 313.15 K. Error analysis of the measured results is presented. Measurements were compared with predictions given by UNIFAC and COSMO-RS. All systems exhibited positive deviation from Raoult's law and azeotropic behaviour was found for the systems 2-methylpropane + methanol and 2-methylpropane + ethanol.
