Vapor Pressures and Vaporization Enthalpy of 2‑Ethoxyphenol

The saturated vapor pressures were measured for samples of mole fraction purity of 0.9998 of 2-ethoxyphenol over the temperature range (380.221 to 486.033) K by comparative ebulliometry. Replicate measurements were performed to estimate precision measures for all measured data. The experimental data...

Description
Summary:The saturated vapor pressures were measured for samples of mole fraction purity of 0.9998 of 2-ethoxyphenol over the temperature range (380.221 to 486.033) K by comparative ebulliometry. Replicate measurements were performed to estimate precision measures for all measured data. The experimental data were correlated by means of the multiresponse maximum likelihood method, and overall measures of data reproducibility are given. The Antoine and the Frost–Kalkwarf-type equations were used. Variance–covariance parameters were reported for the Antoine equation. The calculation of molar enthalpy of vaporization from saturated vapor data is discussed, and values of the calculated molar enthalpy of vaporization are reported. The value of vaporization enthalpy at normal boiling temperature is compared with literature data and corresponding values obtained by predictive methods.
