ABSTRACT

The total pressure measurements made at 313.15 K by the static method for five binary mixtures 1-Butanol + heptane, + iso-octane, +dodecane, + cyclohexane and + toluene are presented. Data reduction by Barker s method provides correlations for GE, using the Margules equation, also Wilson, NRTL and UNIQUAC models have been used for fitting binary systems. The five investigated mixtures exhibit a positive deviation from ideality. No azeotrope has been detected for 1-butanol + dodecane, the other systems show positives azeotropy. The good results are obtained in the prediction of the total pressure for these systems.
