ABSTRACT

Excess molar enthalpies, HmE, for the binary mixtures of benzyl alcohol + methanol, ethanol, propan-1-ol, butan-1-ol, pentan-1-ol, and hexan-1-ol were measured over the entire range of composition at 298.15 K and ambient pressure using a Parr 1455 solution calorimeter. From the experimental results the excess partial molar enthalpies, HiE, and excess partial molar enthalpies at infinite dilution, HiE,8, were calculated. While the excess molar enthalpies are negative for the methanol mixture, those for ethanol, propan-1-ol, butan-1-ol, pentan-1-ol, and hexan-1-ol mixtures are positive over the entire range of composition of benzyl alcohol. The experimental data were correlated by the Redlich-Kister equation and the two thermodynamics models (Wilson and nonrandom two-liquid, NRTL).
