The vapor pressure and vaporization enthalpy of squalene and squalane by correlation gas chromatography

Vapor pressures and vaporization enthalpies of both squalane and squalene are evaluated by correlation gas chromatography using n-alkanes as standards. Vapor pressures as a function of temperature from T = (298.15–600) K are fit to a second order polynomial. Vaporization enthalpies of (134.4 ± 2.4 and 139.8 ± 2.4) kJ mol−1 and vapor pressures of p = ((15 ± 5.4) and (3.7 ± 1.3))·10−7 Pa at T = 298.15 K are evaluated for squalane and squalene,...
