The density of these materials at or near room temperature is an important physical property for the assessment of their detonation and combustion performances. A novel method is introduced here for the prediction of the density of various classes of organic compounds, including different derivatives of triazole, tetrazole, triazine, tetrazine, furazan, and some organic nitrogen-containing chains. The core model is based on elemental composition, where its reliability has been improved by considering some molecular fragments including specific functional groups. The high reliability of these simple model has been compared with the output from two complex quantum mechanical approaches. For 91 high nitrogen compounds, the values of the standard deviation ( SD ) of the core and improved correlations were 0.076 and 0.047 g·cm –3 . For a further 32 materials, the values of SD were 0.057 and 0.042 g·cm –3 for the core and improved correlations, respectively. These data are close to core and improved quantum mechanical methods, i.e. 0.056 and 0.042 g·cm –3 , respectively, where the calculated data from complex quantum mechanical approaches were available. organic compounds, molecular structure, clean enormous energy release","PeriodicalId":9679,"journal":{"name":"Central European Journal of Energetic Materials","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43433426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized GAP and triblock copolymer were characterized by Fourier-transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), and nuclear magnetic resonance spectroscopy (1H and 13C NMR). The thermal stability of the triblock copolymer PPG-GAP-PPG was studied by differential scanning calorimetry (DSC) and thermogravimetry (TG). The DSC results showed that the glass transition temperature (Tg) of the triblock copolymer (Tg = −63 °C) was lower than that of neat low molecular weight GAP (Tg = −53 °C). Furthermore, the results indicated that this triblock copolymer is more stable than GAP. The influence of heating rate (10, 20, 30 and 40 °C·min−1) illustrated that increasing the heating rate results in an increase in the triblock copolymer’s decomposition temperature. Non-isothermal methods, proposed by ASTM E698, Flynn-Wall-Ozawa (FWO) and Kissinger, were used to calculate the kinetic parameters, such as activation energy and frequenc factor, for the thermal decomposition of the triblock copolymer PPG-GAP-PPG, using the DSC-DTG Central European Journal of Energetic Materials ISSN 1733-7178; e-ISSN 2353-1843 Copyright © 2020 Łukasiewicz Research Network – Institute of Industrial Organic Chemistry, Poland 263 Study on the Thermal Stability and Decomposition Kinetics...

The heat of combustion was determined in a calorimeter and the pressure history was measured in a manometric bomb. Ballistic parameters, such as maximum pressure, propellant force and covolume of gaseous products, as well as the dynamic vivacity, were determined based on the experimental results. The sensitivities to friction and impact were determined for the tested propellants. Calculations of the ballistic characteristics (the heat of combustion, propellant force, covolume and ratio of specific heats of the combustion products, and ballistic energy) were performed. The theoretical parameters were compared with the experimental data and quite good agreement was found between them. The largest differences occurred in the cases of propellant force and covolume. This disagreement is explained. An analysis of the test results and a comparison of the parameters of the RDX-based propellants and the JA2 propellant allowed the possibility of using the tested propellants in ammunition to be assessed.","PeriodicalId":9679,"journal":{"name":"Central European Journal of Energetic Materials","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41821469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
