The vapor pressure and vaporization enthalpy of pristane and phytane by correlation gas chromatography

The vapor pressure and vaporization enthalpy of pristane and phytane, two compounds of interest to paleobotanists investigating the antiquity of life, have been evaluated and compared to existing values by correlation gas chromatography. Vapor pressures have been evaluated from T = (298.15–550) K for both pristane and phytane. Both sets of values were fit to a second order polynomial. Comparison with existing literature values for pristane over...
