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
In the production process of RDX from the reaction of hexamine and nitric acid, its reaction rate was evaluated and expressed as -r(A)=1.234X10(6)e (-5671.062/T) CNOCA1.28, 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 phi(c)=20.437-4.805/[1+exp(336.7beta-15.65)]. Its heat transfer coefficient at critical runaway condition was also estimated and expressed as (hS/V)(er)=(Rq(g)AC(NO)C(N)(AO))\(Ebeta(2)e(1/beta)phi(C)). (C) 2002 Elsevier Science Ltd.
