摘要：

Vapor pressures of triadimefon {1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butanone} were measured between 25 degrees C and 70 degrees C, using a gas saturation technique with XAD-2 adsorbent vapor traps. Vapor pressures ranged from (2.25 +/- 0.24) x 10(-4) Pa to (8.72 +/- 0.29) x 10(-2) Pa. The experimental results were related to temperature by the equation log p/Pa = (15.87 +/- 0.35) - (5802 +/- 113)K/T. The calculated molar enthalpy of sublimation was found to be (111.1 +/- 2.2) kJ.mol(-1) and shows no significant temperature dependence in the temperature range investigated.
