Making Picric Acid from Aspirin by the Jolly Roger
|
||
|
|
|
||
|
|
Picric Acid can be used as a booster explosive in detonators, a high
|
||
|
|
explosive charge, or as an intermediate to preparing lead picrate.

Procedure:
|
||
|
|
---------
|
||
|
|
|
||
|
|
1) Crush 20 aspirin tablets in a glass container. Add 1 teaspoon of water
|
||
|
|
and work into a paste.
|
||
|
|
2) Add approximately 1/3 to 1/2 cup of alcohol (100 millilitres) to the
|
||
|
|
aspirin paste; stir while pouring.
|
||
|
|
3) Filter the alcohol-aspirin solution through a paper towel into another
|
||
|
|
glass container. Discard the solid left in the paper towel.
|
||
|
|
4) Pour the filtered solution into a glass or ceramic dish.
|
||
|
|
5) Evaporate the alcohol and water from the solution by placing the dish
|
||
|
|
into a pan of hot water. White powder will remain in the dish after
|
||
|
|
evaporation.
|
||
|
|
|
||
|
|
NOTE: The water in the pan should be at hot bath temperature, not boiling,
|
||
|
|
approx. 160 to 180 degress farenheit. It should not burn the hands.
|
||
|
|
|
||
|
|
6) Pour 1/3 cup (80 millilitres) of concentrated sulfuric acid into a
|
||
|
|
canning jar. Add the white powder to the sulfuric acid.
|
||
|
|
7) Heat canning jar of sulfuric acid in a pan of simmering hot water bath
|
||
|
|
for 15 minutes; then remove jar from the bath. Solution will turn to a
|
||
|
|
yellow-orange color.
|
||
|
|
8) Add 3 level teaspoons (15 grams) of potassium nitrate in three portions
|
||
|
|
to the yellow-orange solution; stir vigorously during additions. Solution
|
||
|
|
will turn red, then back to a yellow-orange color.
|
||
|
|
9) Allow the solution to cool to ambient room temperature while stirring
|
||
|
|
occasionally.
|
||
|
|
10) Slowly pour the solution, while stirring, into 1-1/4 cup (300
|
||
|
|
millilitres) of cold water and allow to cool.
|
||
|
|
11) Filter the solution through a paper towel into a glass container. Light
|
||
|
|
yellow particles will collect on the paper towel.
|
||
|
|
12) Wash the light yellow particles with 2 tablespoons (25 millilitres) of
|
||
|
|
water. Discard the waste liquid in the container.
|
||
|
|
13) Place articles in ceramic dish and set in a hot water bath, as in step
|
||
|
|
5, for 2 hours.
