Implication

Experimental study demonstrates thermodynamic excess properties in propiophenone-alcohol mixtures, highlighting temperature-dependent molecular interactions.

Key Points

  • To examine intermolecular interactions and thermodynamic deviations in binary mixtures of propiophenone with 1-propanol, 1-butanol, and 1-pentanol across varying temperatures and compositions.
  • Measured densities and ultrasonic speeds of sound across the entire composition range at 303.15, 308.15, 313.15, and 318.15 K under atmospheric pressure (0.1 MPa).
  • Calculated thermodynamic excess parameters, including excess molar volume, ultrasonic velocity, acoustic impedance, intermolecular free-length, and isentropic compressibility deviation.
  • Fitted excess property data to the Redlich-Kister polynomial equation to derive binary coefficients and standard deviations, and computed partial molar volumes.
  • Generated temperature-dependent excess molar properties and acoustic deviation profiles across full mole-fraction ranges for all three binary systems.
  • Established binary coefficients and standard deviations between measured and calculated data using Redlich-Kister equation fitting.
