Novel methods for producing 1,2,4-triazoI-3-one from semicarbazide hydrochloride and formic acid are provided. In methods of this invention, ethanol is used in removal of unreacted formic acid to increase yield and purity of produced 1,2,4-triazol-3-one.
two CuII ions in a syn‐anti mode, which decreases its sensitivity but has no influence on its explosive properties. Based on the results of thermogravimetric and differential scanning calorimetry analyses, MOF 1 displays a rapid thermal decomposition process and superior thermostability. The non‐isothermal kinetics of the exothermic process of 1 were studied by the methods of Kissinger and Ozawa. The

demonstrated that the twocomplexes have good thermostability, up to 238 °C for 1 and 270 °C for 2. The non-isothermal kinetics for exothermic processes of the complexes were studied using Kissinger's and Ozawa's methods. The calculated detonation properties and sensitivity tests showed that both complexes could be used as potential explosives. In addition, the twocomplexes were explored as combustion

A new energetic complex, Cu(TO)(2)(HDNBA)(2)(DNBA)(2 )(1) (TO = 1,2,4-triazole-5-one, HDNBA = 3,5-dinitrobenzoic acid), has been synthesized and characterized. Structural analysis reveals that 1 possesses a 3D supermolecular architecture with mononuclear Cu(II) unit and mixed building blocks. TG and DSC analyses of 1 display a rapidly one-step thermal decomposition process and relatively high thermostability up to 498 K. The non-isothermal kinetics of exothermic decomposition process of 1 was studied. Based on the solution calorimetry, a thermochemical cycle was designed to determine the enthalpies of solution of reactants and products of coordination reaction of 1 by using a RD496-2000 microcalorimeter at 298.15 K The standard molar enthalpy of formation of 1 was determined to be -(1585.7 +/- 2.3) kJ.mol(-1). The detonation properties of 1 were calculated by an effective empirical method using the standard molar enthalpy of formation. The calculated heat of detonation of 1 is equivalent to that of TNT and higher than some known energetic complexes, such as CHHP and ZnHHP. (C) 2018 Elsevier Ltd. All rights reserved.
