Abstract

The saturated vapor pressures of a series of α-pinene derivatives including camphene, isobornyl acetate, (±)-limonene, dihydromyrcenol, pinane, and dihydromyrcene were determined at the pressure ranging from (0.8 to 50.0) kPa by the boiling point method. Good agreement of the correlated values was obtained when the experimental data of vapor pressure and temperature were correlated by the Antoine equation, and the parameters A, B, and C were estimated. The molar enthalpies of vaporization ΔvapHm of these compounds were estimated within the experimental temperature range by the Clausius–Clapeyron equation. Furthermore, the reliability of regressed parameters obtained from the Antoine equation in the range of experimental data was verified.
