Explosive properties of sym-trinitrobenzene

The lead block test is 330 cm3, and compared with picric acid (taken as 100), it is 108-111. 

The sensitiveness to impact is slightly lower than that of TNT. According to Wohler and Wenzelberg [25], an impact energy of 12.1 kgm/cm2 is necessary to produce 50% explosion. Thus compared with picric acid (100) its relative sensitiveness is 109, i.e. to bring about an explosion, the impact energy has to be higher by 9% than that necessary to explode picric acid.
