Abstract

The (liquid+liquid) equilibria of {x1CH3CN+x2C2H5OH+(1-x1-x2)C7H16} and {x1CH3CN+x2CH3(CH 2)2OH+(1-x1-x2)C7H16} at the temperature T=313.15 K, and {x1C6H5NH2+x2CH3OH+(1-x1-x2)c-C6 H12} at T=298.15 and T=298.15 and T=300.15 K have been measured. At T=298.15 K the last mixture has only one region of immiscibility, while at T=300.15 K the mixture has two separate biphasic regions. The experimental values have been compared with those predicted with the modified UNIQUAC and extended UNIQUAC models having only binary parameters.
