Experimental vapour-liquid equilibrium data for the binary mixtures ethyl acetate + pyridine, n-propyl acetate + pyridine and n-butyl acetate + pyridine have been determined at 101.325 kPa. The Wilson, NRTL, LEMF, UNIQUAC and Effective UNIQUAC equations have been fitted to the data, which have also been used to establish UNIFAC parameters for interaction between CCOO and PYRIDINE groups.
