摘要

The experimental excess molar enthalpy, H_m^E, data are reported for 1-alkanols (2), namely, {methanol, ethanol, 1-propanol, 1-butanol and 1-pentanol} in cyclopentanone (1) at T = 298.15 K and ambient pressure over a whole range of mole fractions. The values of H_m^E data are positive over the whole range of mole fraction and the magnitude of H_m^E data also increases with increasing chain length of 1-alkanols. The Peng-Robinson-Stryjek-Vera (PRSV) equation of state (EOS) has been used to predict the experimental H_m^E data. As a comparison with PRSV EOS, the ERAS-model was applied for simulation of the experimental excess molar enthalpy to describe the experimental H_m^E data.
