1
Q
what is a clandestine explosive?
A
are improvised explosives made from widely available chemicals in an uncontrolled way
often being unaware of the products formed
2
Q
Acetone peroxide
A
most common clandestine explosive (trimer TATP or dimer DATP form)
- very oxygen deficient - doesn’t conform to K-W rules
- is an entropic explosion (large gas vol. but no fireball)
- endothermic reaction
3
Q
detection of TATP
A
no strong UV or visible light absorption = HPLC not possible
not sensitive and not good for trace amounts
4
Q
ANFO
A
nitrobenzene + ANFO = ‘Annie’ used in 1980-90s in the IRA
