Friction Sensitivity of Nitramines. Part Ⅲ:Comparison with Detonation Performance

摘要

The friction sensitivities (FS) of five linear and eight cyclic nitramines have been determined.These FS values were compared with the respective detonation velocities,D,and with the dimensionless ratio created by relating the heat of explosion,Qreal,to the activation energy,Ea,of non-autocatalyzed thermal decomposition of the explosives concerned.For the nitramaines studied,these comparisons show a general trend of FS decreasing with increasing energy content.%The friction sensitivities (FS) of five linear and eight cyclic nitramines have been determined. These FS values were compared with the respective detonation velocities, D, and with the dimensionless ratio created by relating the heat of explosion, Qreaf, to the activation energy, Ea , of non-autocatalyzed thermal decomposition of the explosives concerned. For the nitramaines studied, these comparisons show a general trend of FS decreasing with increasing energy content.
