Thermochemische untersuchungen an nitraminen

Heats of combustion of seven nitramines were determined by calorimetric measurement from which standard enthalpies of formation could be derived. By means of differential scanning calorimetry (DSC) heats of fusion were measured of those substances which have a fusion point below their decomposition temperature (tetryl, methyltetryl, ethyltetryl). Heats of transformation of the four known polymorphic forms of octogen were ascertained. Specific heats (C_p) of the seven compounds are indicated for the temperature region from ?7O°C up to beginning decomposition.
