Aus Urbanski:

Decomposition of TNT during detonation, dependent on a number of factors may be represented (Kast [57]) by the following equation:
16C7H5(NO2)3 = 20CO2 + 47CO + CH4 + H2O + 2C2H2 + 2HCN + 14.5 H2 + 21.5 N2 + + 3NH4HCO + 29C
The heat of explosion of TNT is 950 kcal/kg, the volume of gases V0 = 690 l/kg, the temperature t = 2820°C.

Schmidt gave [111] a number of the equations for TNT decomposition; calculated on 1000 g (4.4 moles) of trinitrotoluene. Here are two of them, for the extreme density of loadings d = 1.0 and 1.59 g/cm3

(1) for A = 1.0 g/cm3
4.4C7H5(NO2)3 = 2.84CO2 + 17.0CO + 3.77H2O + 2.49H2 + 0.1CmHn + 0.1CH4 + + 2.85NH3 + 0.47HCN + 0.2C2N2 + 4.75N2 + 10C
The heat of explosion = 910 kcal/kg, the volume of gases V0 = 773 l./kg, t = 3080°C.

(2) for d = 1.59 g/cm3
4.4C7H5(NO2)3 = 5.47CO2 + 9.39CO + 6.09H2O + 1.63H2 + 0.03CmHn + 0.42CH4 + + 1.5NH3 + 0.32HCN + 0.3C2N2 + 5.39N2 + 14.6C
The heat of explosion = 1085 kcal/kg, the volume of gases V0 = 685 l./kg. I = 3630°C.
