Isobaric vapour-liquid equilibrium for the binary mixtures of 2-methyl-2-propanol with some halohydrocarbons at 40.0 and 101.3 kPa
Vapour-liquid equilibria of the binary systems 2-methyl-2-propanol+chlorocyclohexane, chlorobenzene, bromocyclohexane or bromobenzene have been determined at two constant pressures, 40.0 and 101.3 kPa. The equipment used was a dynamic recirculating still. The isobaric VLE data have been found to be thermodynamically consistent according to the point-to-point test of Van Ness. The activity coefficients have been correlated with the mole fraction through Margules, van Laar, Wilson, NRTL and UNIQUAC equations, and they have been compared also to the predictions obtained using ASOG and UNIFAC group contribution methods.
