R.D.X. MFG.
KA PROCESS:
The "KA" process is a modified process for the nitration of hexamine to R.D.X. It is not as easy as the "E" process but yields are very good and it requires less acetic
anhydride. It does require concentrated nitric acid (90%+) and requires the hexamine to be nitrated to it's dinitrate form first. The product does not contain as much H.M.X.
as a byproduct. This amount will be approximately 1-3% H.M.X. The "KA" process requires smaller amounts of chemicals due to the lower amount of water produced.
CAUTION: Nitric acid and acetic anhydride are both very dangerous chemicals. They are caustic and dangerous. The vapors and all contact with them should be avoided.
This procedure should be done with good ventilation and with proper protective gear.
PROCESS:
Dissolve 50 grams of hexamine (see Kitchen Improvised Plastic Explosives) in 150 ml. of water. To this is added 70 ml. nitric acid (70%) until the solution is acid to litmus
paper. A white precipitate is formed and is filtered out of the solution. This precipitate is hexamine dinitrate. It is thoroughly dried and is ready for the next step of the
process. 95 grams of this white dinitrate is placed in a beaker or wide mouth jar. In another container place 60 grams of ammonium nitrate and 47 grams of 90%+ nitric acid.
To the 95 grams of white dinitrate add 228 grams of acetic anhydride. Add the ammonium nitrate/nitric acid mixture to the acetic acid/hexamine dinitrate solution. A vigorous
reaction will take place. After the reaction subsides the liquid is filtered. The product thus obtained is washed twice with cold water twice with boiling water. It is
dried and dissolved in the least amount of boiling acetone possible. This acetone is chilled and the product will fall out. Reduce the volume of the acetone to 1/2 by boiling
and chill and filter again. Allow the acetone to evaporate and the type "B" R.D.X. is ready to use.
CAUTION: Acetone is very flammable and great care should be used in handling it. Avoid breathing the fumes of acetone.

MANUFACTURE
Place 21 grams of finely powered polyisobutylene in a glass container. To this is added 100 ml of unleaded gasoline (camp stove gasoline). This is allowed to stand until the
P.I.B dissolves completely. To this liquid is added 53 grams of ethyl hexyl sebecate (Di-(2-ethylhexyl) sebecate) and 16 grams of ten weight nondetergent motor oil. Allow
60 ml of the gasoline to evaporate and then mix, by kneading with gloved hands, with 910 grams type B R.D.X. (see R.D.X. section of this book). This is kneaded
until a uniform mixture is formed. It is then rolled out thin and allowed to set for two hours. It is again kneaded for S minutes with gloved hands. This rolling out and kneading
process is repeated until the gasoline can no longer be smelled. The final product will be plastic from -60 to 170 degrees F. It will be a dirty white to light grey in color and
will have the consistency of a stiff putty. P.E.T.N. could replace all or part of the R.D.X. as could most crystalline high explosives.
Acetic anhydride is commonly available and thus most likely could be bought. The commercial product as always will be more consistent and much easier and more
expedient. This process does however work. Efficiency is in the 85 to 90% range based on the amount of acetone used.
