摘要
The experimental excess molar enthalpy, HmE, 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 HmE data are positive over the whole range of mole fraction and the magnitude of HmE 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 HmE data. As a comparison with PRSV EOS, the ERAS-model was applied for simulation of the experimental excess molar enthalpy to describe the experimental HmE data.
