Kinetic parameters of overall gas-phase reactions for propellants based on ammonium perchlorate and polybutadiene binder

A technique is described for calculating the thermal kinetic parameters of an overall reaction $\nu_1$A$_1$ + $\nu_2$A$_2$ $\to$ $\nu_3$A$_3$ + $\nu_4$P which approximates a multistage kinetic mechanism. The stoichiometric coefficients $\nu_i$, the rate constant and order of the reaction, and the thermodynamic parameters of the reagents A$_i$ and final reaction product P are obtained at pressures $p$ = 10–100 atm using the heat release functions based on kinetic schemes describing the chemical structure of the flames of ammonium perchlorate and homogeneous composite propellants consisting of ammonium perchlorate and polybutadiene binder.
