NITRIC ACID/NITROBENZENE ("HELLHOFFITE") EXPLOSIVE

An explosive munition can be made from mononitrobenzene and nitric acid. It is a simple explosive to prepare. Just pour the mononitrobenzene into the acid and stir.


MATERIALS REQUIRED: SOURCES:
Nitric acid
Field grade or 90% concentrated
(specific gravity of 1.48)
Mononitrobenzene (also known as nitrobenzene)
Drug store (oil of mirbane)
Chemical supply house
Industries (used as solvent)
Acid resistant measuring containers. Glass, clay, etc.
Acid resistant mixing rod
Blasting cap
NOTE: Prepare mixture just before use.


 

PROCEDURE:

1.  Add 1 volume (cup, quart, etc.) mononitrobenzene to 2 volumes nitric acid in bottle or jar.

2. Mix ingredients well by stirring with acid resistant rod.

 


 

CAUTION: Nitric acid will burn skin and destroy clothing. If any is spilled, wash off immediately with a large amount of water. Nitrobenzene is toxic; do not inhale fumes.

 

HOW TO USE:

1. Wax blasting cap, pipe and end cap.
