Popis: Total pressure measurements made at 313.15 K by the static method for five binary mixtures 1-butanol + heptane, 2,2,4-trimethylpentane, dodecane, cyclohexane, and methylbenzene are presented. Data reduction by Barker's method provides correlations for GE, using the four-parameter Margules equation; also the Wilson, nonrandom two-liquid (NRTL), and universal quasichemical activity coefficient (UNIQUAC) models have been used for fitting binary systems. The five investigated mixtures exh ibit a positive deviation from ideality. No azeotrope has been detected for 1-butanol + dodecane, and the other systems show positive azeotropy. Good results a re-obtained in the prediction of total pressure for these systems.
