ABSTRACT

Reliable azeotropic data have been measured for the following binary systems: 1-methoxy-2-propanol + toluene, 1-methoxy-2-propanol + cyclohexane, and 2-butoxy ethanol + decane by means of a wire band column. Additionally, molar excess enthalpies (HE) for the four binary systems of benzene and cyclohexane with 1-methoxy- 2-propanol and 2-butoxy ethanol at 313.15 K have been measured using an isothermal flow calorimeter. The azeotropic data were compared with predicted data by Modified UNIFAC (Dortmund). The HE data measured are in good agreement with the predicted results using Modified UNIFAC (Dortmund).
