The effect of various metal complex catalysts of tetraaza-(14)-anurene on the thermal decomposition of ammonium nitrate,
ammonium perchlorate and a solid propellant containing ammonium perchlorate as an oxidizer was studied by thermal analysis and
burning rate measurements. The following results were obtained.
A metal complex, which had iron or vanadium as a central metallic ion, showed high activity during the thermal decomposition
of ammonium nitrate. Especially, this activity became high when chloride and perchlorate ions were combined with iron or vanadium
ions.
Iron and vanadium catalysts also had high activity during the thermal decomposition of ammonium perchlorate and its solid
propellant. For the solid propellants which contained iron or vanadium complexes as catalysts, the burning rate increased by 1.6
times and their n index decreased to 80% compared to the burning experiments without a catalyst at a pressure of 5.0 MPa.
硝酸アンモニウム, 過塩素酸アンモニウムおよび過塩素酸アンモニウムを含む固体推進薬の熱分解に及ぼすテトラアザ−14−アヌレンの種々の金属錯体触媒の効果を，熱分析や燃焼実験によって検討した。
硝酸アンモニウムの熱分解には中心に鉄やバナジウムを配位した触媒が高活性を示した。その際，鉄やバナジウムに塩素や過塩素酸イオンを結合させた錯体の活性が特に高かった。過塩素酸アンモニウムの熱分解や過塩素酸アンモニウムを含む固体推進薬の熱分解や燃焼反応にも鉄やバナジウム錯体が高活性を示した。
