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 (2E,4E)-3,7,11-trimethyl-2,4-dodecadienoate, R,S-2-propynyl (2E,4E)-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.
