… Vomiting Gas …
Chloropicrin: Chloropicrin is also known as vomiting gas. Though not really
a
gas but a liquid, the inhalation of it’s mist or fumes causes projectile
vomiting in humans.
It’s production is easy but requires some special
equipment. Needed are a chemical hood or
glove box, protective clothing and
a gas mask or clean air respirator. The gas mask must be
impermeable to the
fumes of chloropicrin as the chemical is known to penetrate most masks.
Chloroform in
your box or hood. Also needed is about 1/2 lb. of plaster of
paris. Put on your protective
clothing and turn on the exhaust of the hood.
Slowly pour the nitric acid into the chloroform
while stirring and cooling
the mixture. The acid is added a little at a time. When all the
acid is added
continue stirring for 15 min. The reaction flask contains chloropicrin and
water. This water will hydrolize and destroy the chloropicrin after a while
and must be
removed. This is where the plaster comes in. Added a tsp. of
plaster and stir. Continue adding
the plaster and stirring until about 6 oz.
of plaster is in the mix. Cap the flask and let the
plaster settle out.
When all the plaster is settled, filter the chloropicrin through filter
To make fuming
nitric acid take red fuming nitric acid and add a little
urea. Blow dry air through it until
the red fumes stop coming off.
Chloropicrin (known in chemwarfare circles as PS) can be
mixed with either
CN or CS teargas. The makes a very nasty chemweapon. The effects of both
hour or so but
can continue for a week or more.
