Vaporization Enthalpies and Vapor Pressures of Some Insect Pheromones by Correlation Gas Chromatography

The vaporization enthalpies and vapor pressures of the following insect pheromones at  T /K = 298.15 have been evaluated by correlation gas chromatography:  Z -8-dodecenyl acetate,  Z -4-tridecenyl acetate,  E -11-tetradecenyl acetate,  E , E -9,11-tetradecadienyl acetate,  S -ethyl (2 E ,4 E )-3,7,11-trimethyl-2,4-dodecadienoate,  R , S -2-propynyl (2 E ,4 E )-3,7,11-trimethyl-2,4-dodecadienoate, and  Z -13-octadecenyl acetate. Also evaluated are vapor pressures as a function of temperature from  T /K = 298.15 to 500 which have been fit to a third-order polynomial. Normal boiling temperatures are predicted by extrapolation. The results are compared to available literature values.
