RDX with E-Synthesis.
At Begin You must know the yield of the E-Synthesis are
very bad. (only 15 % of NOX from ammonium nitrate goes into reaktion)
You can get with the amount`s of Megalomanias Page
(260 ml acetic anhydride, 105 g ammonium nitrate, 38 g
paraformaldehyde) max. 12 - 15 % from paraformaldehyde.
The yield is max. 5.5 g RDX type B.
Procedure:
When you begin after heating the AN/AA mixture up to 90C
remove from heat-source and add "verry slowly" the paraformaldehyde or the raktion-temperature will rise high and the AA-liquid evaporate
in short time !!!!
Add max. 1 g portions over 20-25 min. and wait for reakt.
(be careful - toxic fumes, irritating skin and eyes !!!)
Holt temperature between 60C and 70C and control with thermometer, putting in and out in cold/hot water-bad.
After all adding and reakting dump the solution (little brown/red) into 400 ml cold "destilled water".
an let stand for 3-4 hours to full precipitate RDX.
After precipitate RDX (very big little-yellow/brown crystal-splinter)
filter and dry crystals at room temperature for 24 hours.
It`s necessary to purificate the RDX with acetone to remove many
impurities or you have big problems to detonate the crude product.
I used self-made acetic anhydride (from acetyl chloride and sodium acetate) and ammonium nitrate.
The paraformaldehyde i bought in chemical store (it`s to difficuld for self-made ).
At finnish i can say to make large quantitys of RDX with E-Synthesis it`s a very expensive and costly and precisely worked.
In industrial reactors they produce "100 Kg RDX-B" with 5000 Kg acetic anhydride, 1500 Kg ammonium nitrate and 800 Kg paraformaldehyde. (very expensive !!!!)
