Characteristics of sublimation of traces of trinitrotoluene from the glass surface
A mathematical model of sublimation (evaporation) of thin films of explosives based on the molecular-kinetic theory of evaporation is presented. An expression is obtained for the film evaporation time until equilibrium between the evaporation and condensation of explosives is reached. An estimate of the unevaporated mass is given. A parametric study of the model was carried out. The calculation of evaporation dynamics for a film of trinitrotoluene on glass with a surface density of 100 ng/cm2 is giv. The heat of sublimation of trinitrotoluene and the coefficient of evaporation from glass based on a comparison with the experiment of evaporation of such a film of TNT were determined.
