| Abstract: | The enthalpies of combustion for 3,4,5-trinitro-1Н-pyrazole, 1-methyl-3,4,5-trinitro-1Н-pyrazole, 3,4,5-trinitro-1Н-pyrazole ammonium salt, and ammonium salts of all isomeric dinitropyrazoles and dinitroimidazoles were measured by bomb calorimetry, and the corresponding enthalpies of formation were calculated. The partial contributions to the enthalpies of formation of structurally related compounds were calculated for trinitropyrazole, trinitropyrazolate anion, and anions of isomeric dinitropyrazole and dinitroimidazoles. |
