Vapor pressures and vaporization enthalpy of codlemone by correlation gas chromatography
The vapor pressure and vaporization enthalpy of codlemone (trans, trans 8,10-dodecadien-1-ol), the female sex hormone of the codling moth is evaluated by correlation gas chromatography using a series of saturated primary alcohols as standards. A vaporization enthalpy of (92.3 +/- 2.6) kJ . mol(-1) and a vapor pressure, p/Pa = (0.083 +/- 0.012) were evaluated at T = 298.15 K. An equation for the evaluation of vapor pressure from ambient temperature to boiling has been derived by correlation for codlemone. The calculated boiling temperature of T-B = 389 K at p = 267 Pa is within the temperature range reported in the literature. A normal boiling temperature of T-B= (549.1 +/- 0.1) K is also estimated by extrapolation. (C) 2015 Elsevier Ltd. All rights reserved.
