Abstract: The isoplethic vapor-liquid equilibria(VLE)for N,N -dimethylformamide +2-propanol+1-propanol and their binary constituent mixtures were measured by using an inclined ebulliometer with a pump-like stirrer. The comparison between the experimental results and literature for binary systems was given. The ternary VLE were predicted by using modified UNIQUAC model with temperature-dependence binary parameters.
