How To Make Smokeless Powder
|
|
----------------------------
|
|
|
|
[1> Boil cotton for 30 minutes, in a 2% solution of sodium hydroxide.
|
|
[2> Wash the cotton in hot water and allow it to dry.
|
|
[3> Mix slowly and carefully at 25 degrees Centigrade, 250 cc. of concentrated
|
|
sulfuric acid, 150 cc. of concentrated nitric acid, and 20 cc. of
|
|
water. They must be kept at 25 degrees C.
|
|
[4> Next place the dried cotton in the acid solution, and stir well with
|
|
either a glass or porcelain rod (do not use metal). This should be
|
|
done for 35 minutes.
|
|
[5> After nitration, the acids are washed away, and the cotton is washed in
|
|
boiling water five times, each time for 25 minutes. The cotton is
|
|
given several tests with litmus paper. If the litmus test proves
|
|
that there is still some acid present, a 2% solution of sodium
|
|
bicarbonate should neutralize whatever is left. This is important,
|
|
since any remaining acid acts as an impurity to make the explosive
|
|
more unstable.
