“…-(N2H4 + 2NaC104 + 6000H20) (soln.) + 2H20(1) (1) culations were taken from NBS tables. 3 Since the final state is basic, some consideration was given to the enthalpy change due to a slight shift in the equilibrium N2H6+ + OH-N2H5OH and to the possible decomposition or oxidation of the hydrazine solution.…”

“…To evaluate the accuracy of the methods mentioned above in estimating the enthalpy of formation for perchlorates and nitrates, we used the NIST database [11] and other experimental studies [12][13][14][15] on the determination of the enthalpies of salt formation and collected in Table 2 different cations values. The average value of the difference between the enthalpies of formation for perchlorates and nitrates ΔH an (ClO 4 ) -ΔH an (NO 3 ) from Table 2 is 19.43 kcal mol − 1 , which is quite close to the value according to the MAIC method (Table 1):…”

Based on various calculation methods, the enthalpies of formation for a number of salts of nitric and perchloric acids were estimated. Relationships between the thermochemical characteristics of salts depending on various cations are considered. Calculations have been made and the efficiency of using a number of quantum-chemical methods in estimating the formation enthalpy of compounds in the gas phase has been analyzed. Based on a combination of quantum chemistry methods and Atom-Atom Potentials, the crystal structure of salts was simulated and the enthalpy of sublimation was estimated for subsequent use in calculations by the recently developed MICCM method. This method surpasses all the most commonly used calculation schemes in terms of accuracy in estimating the enthalpies of salt formation. Among the compounds considered, the calculations of the salts enthalpies of three amino-1,2,4-triazoles showed a significant discrepancy with the experimental data.

“…Unfortunately, their application is still plagued by developmental problems relating to their thermal stability, storability, impact and friction sensitivity, and hygioscopicity (36). The research effort in this field of high energy oxidizers is still in its infantile stages; cnly now, are papers starting to appear in this field (156)(157)(158)(159)(160)(161)(162)(163)(164)(165). The only general remarks that can be made is that they usually melt around 200°C (36) and that they usually decompose in a manner similar to ammonium perchlorate, i.e., they gc through a dissociative gasification step followed by an exCthermic gas-phase reaction stage (36,(160)(161)(162).…”
