Vaporization enthalpies and liquid vapor pressures, have been evaluated at T/K = 298.15 for phencyclidine, a hallucinogen (PCP, Angel Dust) and fenpropidin, a fungicide by correlation gas chromatography. Both substances are aliphatic tertiary amines. Vapor pressures of liquid fenpropidin and subcooled liquid phencyclidine have been evaluated over a T/K = 30 temperature range. The fusion enthalpy of phencyclidine has been estimated by a group method and together with its vaporization enthalpy and subcooled liquid vapor pressure at Tfus, a sublimation enthalpy and vapor pressure of crystalline phencyclidine has also been estimated at both T/K = (Tfus and 298.15). A comparison of current results with limited amounts of both experimental and estimated data from the literature is quite good.
