Outline of Final Research Achievements

The theoretical calculations for the initial elementary reactions and the development of detailed chemical kinetics models were performed for the comprehensive understanding of the hypergolic combustion of nitrogen-containing propellants used in space craft engines. The dissociation reactions of hydrazine derivatives and the H abstraction reactions by NO2 from those were successfully explained by the methyl substitution effect. In the present study, detailed chemical kinetics model for the thermal decomposition of unsymmetrical dimethylhydrzine was newly developed.
As the low-toxic alternative fuels to the hydrazine derivatives, the initial dissociation steps of tetramethylmethylenediamine and tetramethylethylenediamine were investigated and the concerted elimination of H2 and the C-C and C-N bond fission reactions were found to be important pathways.
