Abstract
Isobaric vapour-liquid equilibrium data are measured at 200, 500 and 707 mm Hg at ten compositions spread evenly over the entire liquid mole fraction range, employing a Swietoslawski type ebulliometer. The liquid phase compos ition vs. bubble temperature (x-t) data are found to be well represented by Wilson model. The optimum Wilson parameters are used to calculate the vapo ur phase compositions, activity coefficients and the excess Gibbs free ener gies.
