I am fairly sure there is no way your going to be able to plasticize AN/Al at home.
Even if you could the 10%-15% inert binder/plasticizer would make an already not very powerful explosive even less powerful.

Use Nitrocellulose/nitroglycerin as plasticiser for the AN/Al...it should work and boost the things up.
But beware of headaches

For AN/Al you will need dark aluminium. Anything else will give inferiour performance or will not work at all with small charges.
You cannot make this yourself. You need to buy it somewhere.
For plastification, try this:

That is exactly how I plasticize it as well Philou, it is essentially aluminized ammonia gelatine dynamite. Maybe with very small amounts of NG &
NC it wouldn't be specified as dynamite anymore. It can be very rubbery depending on the content of NG & NC.

Wow, I never knew you could plasticize AN based explosive.
And using an energetic material to plasticize it sounds good.

What do you use as a solvent when you mix the AN/AL/NC together...? Nitro methane, I have tried (as Yoda would say). But I used smokeless powder, it
did not dissolve well, so a gel it was, instead of plastic (as Yoda would say again!)

I use a little acetone and sometimes a little heat to prepare the NC & NG gelatine first then mix in the finely powdered and well mixed ammonium
nitrate and fuel (whether the fuel is fine aluminum , corn starch or whatever). The vapor pressure of NG at ordinary temperatures is very low while
the vapor pressure of acetone is very high, so most of the acetone can be easily and fairly quickly evaporated away with the loss of very little NG.

can sulfanilic acid be used to make explosives?
Yesterday i read about sulfamic acid and come to know that it contain nitrate.
So can it be used to make explosive???

Sulphanilic or sulphamic acid? You have sulphanilic (sulfanilic) acid in your title and sulphamic (sulfamic) acid in the question beneath.
In one of the threads in the energetic sub-forum there is a reference to an old GB patent for the preparation of picric acid from sulphanilic acid, I
don't have a copy but it was probably posted in that thread. Try using the search engine instead of starting a new thread every time you have a
question.

is it possible to make acetone peroxide in this way??
I want to make acetone peroxide . I also have homemade peroxy disulfuric acid(h2s2o8) which gives h2o2 and di sulfuric acid (h2s2o7) on hydrolysis .
So can i use this mixture instead of h2o2 and few drops of h2so4 for making acetone peroxide.

Disulfuric acid is HO-SO2-O-SO2-OH a kind of anhydride
Its hydrolysis leads to sulfuric acid!
HO-SO2-O-SO2-OH + H-OH --> HO-SO2-OH + HO-SO2-OH
= 2 (HO)2SO2 or H2SO4

This is purely hypothetical, based however on a similar process know to work.
Add it to a stoichiometric ratio of copper (II) hydroxide and heat it.
(NH4)2SO4 + Cu(OH)2 --> 2 NH3 + 2 H2O +
CuSO4
The one problem I can see with this is the ammonium sulfate may boil (decompose) before the copper hydroxide dissolves in the melt, preventing the
ions from exchanging.

I'd do it in solution, rather than trying to melt the salts.

making nitrobenzene
I am wishing to make nitrobenzene for many weeks but in my area benzene is not available easily but yesterday i read on wikipedia that it can be
synthesised by reacting aniline and KMno4 in specific condition .can anybody explain me the whole procedure from A-Z.
And thanks in advance.

So you're saying you have access to aniline but not benzene? That seems odd.

You are right we don't have acess to aniline but my friend has and he had given me a little sample and in future we are going to make aniline from
indigo.

Using the Sandmeyer reaction you could go from phenylamine to its diazonium ion to benzene or straight to nitrobenzene, but the latter is harder.

Your AN must be very dry and away from air moisture...because traces of moisture allow the protective oxyd layer of the aluminium to be chewed by the
NH3 and the HNO3 present in traces in dissociated NH4NO3.
To see what happens...make a saturated solution of NH4NO3 and suspend Al foil schredings into it...after a week or two all the Al will be dissolved as
Al2O3 , Al(OH)O and Al(OH)3. If the recipient is closed, pressure will build up inside and crack or expel the cap...probably some hydrogen is formed
by the decomposition of the water in contact with the naked aluminium.
2Al(s) + 3H2O(l) --> Al2O3(s) + 3H2(g)

So, CAN I detonate a 100g AN/AL charge with 1g of tatp in copper pipe?
Thanks!  |
Is CTAP (cyclo-triacetone peroxyde) stable towards copper, Cu(OH)2 or Cu(2+)?
--> Answer is no; those are not storage advisable!
Peroxydes don't like copper and many transition metals!
Is AN/AL stable towards copper, Cu(OH)2, Cu(2+)?
--> Answer is no; oxydised Cu and metallic Al form a battery in shortcut...thus heating, AN complexes Cu, Cu(OH)2 and Cu(2+) as Cu(NH3)4(NO3)2...
All this is thus not storage advisable, especially if the AN is not well dried and protected from the air.
Better coat the Cu with a varnish/lacker.

The other problem is the formation of CuSO4.xH2O and the complexation of NH3 as Cu(NH3)4SO4...thus more heat and time will be needed to expel fully
the NH3 and the H2O.
