Measurement of detonation failure diameter in thin layers of an explosive solution

The detonation failure diameter was determined for mixtures of dinitrotoluene in concentrated nitric acid with zero and negative oxygen balance in flat glass dishes. For mixtures with negative oxygen balance, detonation was detected in layers 0.10 and 0.12 mm thick, and detonation failure took place in layers 0.08 mm thick. The data obtained gives complete form to the dependence of the detonation failure diameter on composition for dinitrotoluene solutions in HNO$_3$.
