The detonation failure diameter df and detonation velocity D of mixtures of nitromethane, trinitrotoluene, dinitrotoluene, and trinitrobenzene with sulfuric acid and oleum have been measured in the wide range of concentrations. It was shown that the detonation ability of the nitrocompounds depends significantly on the sulfuric acid content. The minimum value of df for the mixture TNT/oleum is about 2 mm, i.e., 30 times less, than that for pure melted TNT, and practically equal to df of nitroglycerine. In some cases, the temperature dependencies of failure diameter have been determined. Dremin theory of detonation failure diameter was used to treat quantitatively the results of experiments with the NM and TNT solutions in the frameworks of the Arrhenius chemical kinetics.
