text: why shouldn't 2,4,6 trinitrobenzene be used on its own in a blasting ground (e.g. in coal mines)?   kevin, please look up my answer to your previous question...i think you are still confusing tnb with tnt.  in the case of tnt, it is too shock-sensitive to be handled safely...that is why it is converted to dynamite and set off via percussion caps...fuller info in previous answer.  if you really meant tnb, the 2,4,6 (actually 1,3,5) isomer would be very difficult (and expensive) to make...moreover it would give much less 'bounce to the ounce'  :-))
