Thermogravimetric studies were carried out with double base propellants to find out the rate‐determining stage and to understand the mechanism. The decomposition process can be divided into 3 stages as follows: Diffusion of nitroglycerin takes place in the temperature range 120°C–160°C. Two processes occur in the temperature range 170°C–205°C, namely the dissociation of nitroglycerin and the cleavage of the CO bond, the later being the rate‐determining step. The cleavage of the CO bond is followed by a considerable decomposition of nitrocellulose.
