A mathematical model of sublimation (evaporation) of thin films of explosives is presented based on the molecular-kinetic theory of evaporation. 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 has been carried out. The evaporation dynamics for a film of trinitrotoluene (TNT) with a surface density of 100 ng/cm 2 on the glass is calculated. The trinitrotoluene sublimation heat and the evaporation coefficient from the glass have been determined based on a comparison with the experiment on evaporation of this TNT film
