This report examines the stability of TNT and dinitronaphthalene and their mixtures after their thermal extraction from the shells of artillery munitions by means of water vapor and their use for improvised explosives with high power. The comparison of the baseline explosive mixture with the samples acquired after the water vapor extraction showed no significant differences in their characteristics. Similarly, each of the explosive mixture components (TNT and DNN) after the water vapor extraction, examined separately, did not show significant differences from the original TNT and DNN characteristics.

Technology for utilization of waste single and double based propellants by obtaining porous propellants was worked out. The technology contains the preparation of solutions of waste propellants with concentration up to 20%, mixing with additives, forming a liquid layer with determined thickness, evaporation of some amount of the solvent, leaching liquid components with water and draying the porous propellants. The time for evaporation of some amount of the solvent was determined from the results of the rates of evaporation. The investigated additives were 1-butanol, ethylene glycol and polyethylene glycol 400. The porous propellants with specific density from 0.5 to 0.7 g/cm3 and regular distribution of voids of dimensions from 0.1 to 500 žm were obtained.

Single-base propellants stored for more than 50 years were investigated by quantitative IR spectroscopy. The natural aging of the propellants was made in military storehouse for 9, 12, 18, 29, 36, 40, and 51 years. The change in the propellants was characterized by IR spectra. The most suitable absorbances for qualitative IR analysis of -OH and -NO2 groups and of internal standards were determined. The hydrogen bonds formation was characterized by the shift of the bonds the peak width at half-height.
