The task of the program is fundamental research on advanced solid oxidizers with the aim of understanding their self-deflagration. Hydrazine perchlorate and hydrazine diperchlorate have received, of late, most of the attention. Effort was devoted to elucidating some of the chemistry involved in the deflagration process. Toward this end, a literature review of the thermal behavior of hydrazine and perchloric acid was carried out. This was extended to include a review of reactions of chlorine oxides. The kinetics and mechanisms of the latter compounds, it was discovered, are not very well understood. Hence, some experiments were performed on C1O2 and C1O3, two species which seem likely to be important in oxidizers encountered in the program. In particular we have concentrated on the explosive decomposition of C1O2. It was found to explode by a degenerate chain-branching mechanism at all temperatures and pressure above 54C and a few tenths of a mm Hg. Very long induction periods were observed, and C1O3 was shown to be a critical intermediate. The explosion is promoted by irradiation and by addition of foreign gases.
