Abstract
Although HMX exists in four conformational forms, α, β, γ, and δ, in the crystalline state, the most stable polymorph
at room temperature is the β form [1] . Therefore, this form
was used for this study.
Kinetic data obtained from Differential Thermal Analysis
(DTA) changes in heating rates and at isothermal conditions
showed differences in the observed activation energies in the
three temperature ranges, namely, 473°-506°K, 506°-514°K, and
above 514°K at one atmosphere.
Calculations have been made of the rate of reaction as
a function of time in each of these temperature regimes based
upon the best available model and compared with the experimental
result.
