Evaluations of kinetic parameters and critical runaway conditions in the reaction system of hexamine-nitric acid to produce RDX in a non-isothermal batch reactor
Abstract
In the production process of RDX from the reaction of hexamine and nitric acid, its reaction rate was evaluated and expressed as ‑r A =1.234×10 6e ‑5671.062 T C NO C 1.28 A , where T is the reaction temperature, C A is the concentration of hexamine and C NO is the initial concentration of added nitric acid. The critical condition of runaway reaction for the RDX production in a batch reactor is φ c=20.437‑4.805/[1+exp(336.7 β‑15.65)]. Its heat transfer coefficient at critical runaway condition was also estimated and expressed as ( hS/ V) cr=( Rq g AC NO C n AO)/( Eβ 2 e 1/ β φ C).
