PICRIC ACID Brought to you by: -= Exodus =-

|
|
Picric acid, also known as Tri-Nitro-Phenol, or T.N.P., is a military
|
|||
|
|
explosive that is most often used as a booster charge to set off another less
|
|||
|
|
sensitive explosive, such as T.N.T. It another explosive that is fairly
|
|||
|
|
simple to make, assuming that one can acquire the concentrated sulfuric and
|
|||
|
|
nitric acids. Its procedure for manufacture is given in many college
|
|||
|
|
chemistry lab manuals, and is easy to follow. The main problem with picric
|
|||
|
|
acid is its tendency to form dangerously sensitive and unstable picrate salts,
|
|||
|
|
such as potassium picrate. For this reason, it is usually made into a safer
|
|||
|
|
form, such as ammonium picrate, also called explosive D. A social deviant
|
|||
|
|
would probably use a formula similar to the one presented here to make picric
|
|||
|
|
acid.

phenol (9.5 g) 500 ml flask
|

|
|
|
|||
|
|
concentrated adjustable heat source
|
|||
|
|
sulfuric acid (12.5 ml)
|
|||
|
|
1000 ml beaker
|
|||
|
|
concentrated nitric or other container
|
|||
|
|
acid (38 ml) suitable for boiling in
|
|||
|
|
|
|||
|
|
distilled water filter paper
|
|||
|
|
and funnel
|
|||
|
|
|
|||
|
|
glass stirring rod
|
|||
|
|
|
|||
|
|
|
|||
|
|
1) Place 9.5 grams of phenol into the 500 ml flask, and carefully add 12.5 ml
|
|||
|
|
of concentrated sulfuric acid and stir the mixture.
|
|||
|
|
|
|||
|
|
2) Put 400 ml of tap water into the 1000 ml beaker or boiling container and
|
|||
|
|
bring the water to a gentle boil.
|
|||
|
|
|
|||
|
|
3) After warming the 500 ml flask under hot tap water, place it in the boiling
|
|||
|
|
water, and continue to stir the mixture of phenol and acid for about thirty
|
|||
|
|
minutes. After thirty minutes, take the flask out, and allow it to cool
|
|||
|
|
for about five minutes.
|
|||
|
|
|
|||
|
|
4) Pour out the boiling water used above, and after allowing the container to
|
|||
|
|
cool, use it to create an ice bath, similar to the one used in section
|
|||
|
|
3.13, steps 3-4. Place the 500 ml flask with the mixed acid an phenol in
|
|||
|
|
the ice bath. Add 38 ml of concentrated nitric acid in small amounts,
|
|||
|
|
stirring the mixture constantly. A vigorous but "harmless" reaction should
|
|||
|
|
occur. When the mixture stops reacting vigorously, take the flask out of
|
|||
|
|
the ice bath.
|
|||
|
|
|
|||
|
|
5) Warm the ice bath container, if it is glass, and then begin boiling more
|
|||
|
|
tap water. Place the flask containing the mixture in the boiling water,
|
|||
|
|
and heat it in the boiling water for 1.5 to 2 hours.
|
|||
|
|
|
|||
|
|
6) Add 100 ml of cold distilled water to the solution, and chill it in an ice
|
|||
|
|
bath until it is cold.
|
|||
|
|
|
|||
|
|
7) Filter out the yellowish-white picric acid crystals by pouring the solution
|
|||
|
|
through the filter paper in the funnel. Collect the liquid and dispose of
|
|||
|
|
it in a safe place, since it is corrosive.
|
|||
|
|
|
|||
|
|
8) Wash out the 500 ml flask with distilled water, and put the contents of the
|
|||
|
|
filter paper in the flask. Add 300 ml of water, and shake vigorously.
|
|||
|
|
|
|||
|
|
9) Re-filter the crystals, and allow them to dry.
|
|||
|
|
|
|||
|
|
10) Store the crystals in a safe place in a glass container, since they will
|
|||
|
|
react with metal containers to produce picrates that could explode
|
|||
|
|
spontaneously.
