The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

Derivatives of mesoionic heterocycle azasydnone (oxatriazolium-5-olate derivatives) may be of interest not only as medications, but also as energetic materials. In order to determine the possible applications of a new class of energetic compounds, it is necessary to determine the thermal stability, the combustion behaviors, and other properties of representatives of this chemical class. The thermal stability of the substances was studied by differential scanning calorimetry (DSC) method under non-isothermal conditions and by means of gas evolution method (in Burdon glass manometers) under isothermal conditions. Combustion behavior of pressed samples was investigated in a constant-pressure bomb in a wide pressure interval, and the flame structure was studied with the help of thin tungsten–rhenium thermocouples. Investigation of the thermal stability of the derivatives of azasydnones showed that the heterocycle possesses satisfactory stability. The decomposition of molecules begins with the decomposition of the azasydnone ring, and there is a strong dependence of the thermal stability of azasydones on the nature of the substituent. The heat effect of decomposition of the azasydnone ring consists of the enthalpy of formation (16–20 kcal mol-1) and the heat of oxidation of the carbon atom adjacent to the cycle. It is shown that the introduction of mesoionic heterocycle in nitropyrazoles leads to a decrease in the exponent in the combustion law. It turned out that the decomposition reaction with activation energy less than 30 kcal mol-1 controls the burning rate of these compounds.
