KINETICS OF DECOMPOSITION OF SOLID OXIDIZERS.
Abstract
The purpose of this research has been to study the thermal decomposition of the solid oxidizers, INFO-635P, poly FA-BDE, and BTU, to obtain knowledge of their decomposition kinetics and mechanism. Thermal decompositions of poly FA-BDE were continued with additional experiments in the temperature range 160 - 180 C. The work was done both at low pressure of decomposition gases and under continuous vacuum. Separation and analysis of decomposition products showed that, although secondary reactions between gaseous products and the solid phase had been greatly minimized, the measured decomposition was well advanced as evidenced by the detection of nitrogen in initial samples. Extrapolation of decomposition rates from pressure-time data on poly FA-BDE to rates at zero time and the use of these rates in an Arrhenius plot produced an apparent activation energy for onset of decomposition of 44.4 kcal. A series of experiments in which the solid polymer was examined as a function of time and temperature as it decomposed under continuous vacuum produced a value of 46.9 kcal.
