Abstract熱重量-示差走査熱-高感度飛行時間型質量複合分析(TG-DSC-HRTOFMS)を用いて,アンモニウムジニトラミド(ADN),モノメチルアンモニウム硝酸塩(MMAN),尿素(urea)から構成される高エネルギーイオン液体推進剤の熱-生成ガス同時分析を行った.本手法は,熱挙動と同時に生成ガスの精密質量を測定することができる.ADN/MMANおよびADN/MMAN/ureaの両組成からは,H2O, HCN, CO, N2, CH2O, CH3NH2, HNCO, CO2, N2O,およびHNO3に分解することがわかり,その反応機構を考察した.またureaの吸熱分解によって推進剤の総発熱量は低下することもわかった.
Thermal and evolved gas analyses were carried out to assess the thermal decomposition of high-energetic ionic liquid propellant consisting ammonium dinitramide (ADN), monomethyl ammonium nitrate (MMAN), and urea, using thermogravimetry-differential scanning calorimetry-high resolution time of flight mass spectrometry (TGDSC- HRTOFMS). This technique simultaneously assesses the thermal and evolved gas behavior and is able to distinguish between products having similar mass-to-charge ratios, based on accurate mass determinations. ADN/MMAN and ADN/MMAN/urea mixtures were found to decompose to form NH3, H2O, HCN, CO, N2, CH2O, CH3NH2, HNCO, CO2, N2O and HNO3, and possible reaction pathways for the decomposition processes were developed. The presence of urea reduces the net exothermic heat of reaction due to the endothermic pyrolysis reaction of urea.
