KINETICS OF DECOMPOSITION OF SOLID OXIDIZERS.
Abstract
The degradation of INFO-635P and poly FA-BDE was investigated chiefly by performing decompositions in the temperature range, 160 - 180 C., under conditions of continuous vacuum, and low and high pressure of product gases. In addition, the technique of mass spectroscopic thermal analysis (MTA), complemented by high-resolution mass spectroscopy, was used to study the decomposition under high vacuum where secondary reactions were minimized. Examination and interpretation of the experimental data have shown that INFO- 635P may decompose, after nucleation, by one or more of several paths simultaneously. This multiplicity of reaction mechanisms is mainly a result of the sublimation of INFO-635P, which appears to obey a first order rate law. This physical process is presumed to occur after a series of reactions in the solid phase involving proton transfer and desorption from the solid. Suggestions for desensitization of INFO-635P are given. The early gaseous products of the poly FA-BDE decomposition were identified, and related to the solid phase reaction. The residue was an insensitive and insoluble material believed to be a highly crosslinked polymer. Mechanisms are proposed for the early degradative steps which explain the formation of the observed products. The experimental results give little hope for the desensitization of this material.
