Abstract
The standard enthalpies of combustion and formation for isomeric polynitropyrazoles, viz., 3,4- and 3,5-dinitro-1-trinitromethyl-1Н-pyrazoles, were measured by combustion calorimetry in an oxygen atmosphere. The enthalpies of formation for the 3,4-dinitro isomer by 19.7 kJ mol–1 exceeds the corresponding parameter for the 3,5-isomer.
