Abstract
Temperature dependence of the heat capacity and the parameters of phase transitions of 1-ethyl-4-nitro-1,2,3-triazole (1ET) were studied between 5 and 370 K in a vacuum adiabatic calorimeter. Thermodynamic properties of the 1ET in the condensed state were obtained over the range of 0–370 K. Saturated vapor pressure for crystalline 1ET in the temperature ranges from 313 to 344 K and its enthalpy of sublimation were measured by the Knudsen effusion method. The standard enthalpy of formation for crystalline 1ET at 298.15 K was determined in a static bomb combustion calorimeter. From these data, the standard enthalpy of formation for gaseous 1ET was evaluated. The enthalpy of formation calculated using quantum chemical methods is in excellent agreement with the experimental value.
