Detonation of nitrobenzene and propargyl alcohol

Detonation of mononitrobenzene and propargyl alcohol at reduced pressure is recorded for the first time in 10-mm-diameter steel tubes with a wall thic kness of 13 mm with high-power initiation. The detonation velocities of nit robenzene equal 25-50% of the ideal value obtained from thermodynamic calcu lations. The conditions for stationary detonation propagation are examined and the critical porosities for these materials are computed based on calcu lations of the fraction of material that is heated and burnt up during deto nation. The computations are in good agreement with experiment.
