Molar heat capacities for {isomer of butanediol + methanol} as function of mixture composition and temperature
چکیده انگلیسی


• Heat capacities for (butanediol + methanol) mixtures were measured.
• Molar heat capacities of mixtures and its components were determined.
• Excess functions were calculated.
• Redlich–Kister equation was used.
• Intermolecular interactions are discussed.

Isobaric specific heat capacities for the binary mixtures {isomer of butanediol + methanol} were measured using a differential scanning calorimeter. The isobaric molar heat capacities were determined in the temperature range from (293 to 324) K. The excess molar isobaric heat capacities of mixtures and its components were calculated. The composition dependencies of the excess molar isobaric heat capacities at T = 298.15 K and at T = 323.15 K were fitted by the Redlich–Kister polynomials. The obtained results were analyzed from point of view of the influence of distance of OH groups in butanediol molecule.
