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

SINOPSIS

1,3,3-Trinitroazetidine (TNAZ) is the prospective high-energy explosive with some practically important properties (low sensitivity, high thermal stability, low melting point). The thermal decomposition kinetics of TNAZ have been investigated by the method of volumetry in gas and liquid phase. The gas-phase reaction (the temperature range was 170−220°C) followed the first order kinetics and obeyed Arrhenius equation k = 1015,67±0,6exp[−(40500 ± 1400)/RT] s−1, where R = 1,987 cal·mol−1·K−1. According to IR-spectrophotometric data the complete TNAZ decomposition at 220°C resulted in the formation of N2, NO2, CO2, O2NCH2CHO and the traces of CO and NO. We explained the formation of nitroacetaldehyde (O2NCH2CHO) by the decomposition of intermediate 3,3-dinitroazetidine. The total quantity of the gaseous products non-condensed at normal conditions was about 4 moles per 1 mole of TNAZ. The more complex kinetics has been measured for TNAZ decomposition in m-dinitrobenzene solution (180−231°C). One could observe the small self-acceleration of the process at low reaction conversions (from 10% up to 25%) and gas-formation level increasing from 4 to 5 moles per 1 mole of TNAZ. Simultaneously, the nitrogen content in the gaseous decomposition products was reduced from 14% in the case of the gas-phase reaction to the traces. TNAZ decomposition in solution was described by the Arrhenius equation:
k (s−1) = 1016.60±1.20 · exp[−(44800 ± 2800)/RT] (R = 1,987 cal/mol , r = 0,998)
