Abstractアンモニウムジニトラミドを基材とした共融型イオン性液体の気相領域における詳細化学反応機構を改良することを目的とした.既往の詳細化学反応機構では加味されていないラジカル種による水素引抜き反応に着目し,第一原理計算により反応パラメータを導出した.ADN:MMAN:尿素の系では改良モデルを用いて導出された火炎構造は実験値を精度よく再現した.このことよりADN:MMAN:尿素の気相領域の燃焼はラジカル種の寄与する反応に支援されていることがわかった.一方,MEAN系やアセトアミド系では計算結果と実験結果に解離が見られた.これらの系では凝縮相反応の加味が重要であることが示唆された.
This study aimed to improve the detailed chemical reaction model of ammonium dinitramide-based deep eutectic ionic liquid in gas-phase. Particularly, dehydrogenations by radical species which weren't included into the conventional model were investigated and added into the conventional model. Their reaction parameters were calculated by ab initio approach. On the sample of ADN:MMAN:urea, its stable combustion wave computed by the modified model showed the good agreement with the experimental result. Reactions related with radical species might be effective for the combustion of ADN:MMAN:urea in gas-phase. On the other hand, calculated results of ADN:MMAN:acetamide and ADN: MEAN:urea were different from experimental results. It was suggested the importance of condense phase reactions in these compositions.
