Vapor-liquid equilibrium for binary systems of methyl ethyl ketone and methyl isobutyl ketone

摘要

Atmospheric vapor-liquid equilibrium data of methyl ethyl ketone (MEK) - methyl isobutyl ketone (MIBK) were measured using an improved Rose still and were used to recover the parameters of NRTL and UNIQUAC models. The results show that the simulated results agree well with the experimental data. The mean temperature variation is 0.14°C and the mean mole fraction variation is 0.0023 using UNIQUAC model while the mean temperature variation is 0.17°C and the mean mole fraction variation is 0.0025 using NRTL model. Both models can be used to calculate the atmospheric vapor-liquid equilibrium data of MEK - MIBK.
