ABSTRACT

Excess molar enthalpies of four binary systems for acetophenone + (methanol, + ethanol, + 1-propanol, and + 2-propanol) at T ) (298.15, 313.15, 328.15, 338.15, and 348.15) K and p ) (0.1 and 10.0) MPa were determined by a high-pressure flow-mixing isothermal microcalorimeter. The excess molar enthalpies increased with an increase in the temperature, pressure, and the molecular size of alcohols. The experimental data were correlated by the Redlich Kister equation and three local composition models (Wilson, NRTL, and UNIQUAC).
