Abstractアンモニウムジニトラミド(ADN)は,高酸素バランス,高エネルギー,ハロゲンフリーであることから,固体ロケット推進薬の新しい高性能酸化剤として実用が期待されている物質である.固体ロケット推進薬での実用に向け重要な情報の一つに化学的安定性が挙げられる.本研究ではADNの熱分解機構に着目し,示差走査熱量測定 (DSC)とラマン分光分析を組み合わせ,定速昇温時の発熱挙動と凝縮相中の分解生成物の同時測定を行った.ADNの熱分解は多段階であり,分解初期では,ADNの硝酸アンモニウム(AN)への分解が主反応であることが明らかとなった.さらに昇温を続けるとADNの分解のほかANが寄与する反応が進行することがわかった。
Ammonium dinitramide (ADN) is the promising new energetic oxidizers for solid propellant because of its high oxygen balance and high energy content, and halogen-free combustion products. For practical use of ADN, one of the important characteristics is chemical stability. This study focused on thermal decomposition mechanism of ADN. Its exothermal behavior and decomposition products in condensed phase during constant rate heating were measured simultaneously with differential scanning calorimetry (DSC) and Raman spectrometry. These analyses showed that the decomposition of ADN proceeded via multiple stages. It was found that one of the main reactions at beginning of ADN decomposition is generation of ammonium nitrate (AN). With more heating, not only ADN decomposition but also the reactions involving AN proceeded.
