The 'zippo' ref. should have told me what to expect. . .

The videos were originally intended for Youtube, I apologize for the somewhat unprofessional nature of them. Ill just remove them if all it will do is
make me look bad. I just felt something other than a written description of the event would be appreciated.......

Nice vids.
Somehow i also have had some kind of interest in HDP.
I might be that this was rejected by the industry, that does absolutely not mean that it cant be usefull for amateur use.
For example AgNO3/AgC2 is used by a lot of amateurs while for the industry it has no use what so ever.
Btw i found this on google:
http://video.aol.co.uk/video-detail/hexamine-diperchlorate-s...
Uhm it is quite sad to see the guy doing the stuff (he calls it getto style ughum does that mean the same as idiot style? ).
Measuring out NH4ClO4 using his bare vingers, well what ever.
Also according to some sources HDP is rated 116%.
Also i found this patent: US Patent 4340755
It is about biguanide diperchlorate.
A small cutout:
| Quote: |
EXAMPLE 1 Biguanide (3.0 g, 101.11 g/mol; 2.96×10 -2 mol) was added gradually as a solid to perchloric acid (10.3 mol, 5.78 N) in an ice bath. The
solution was evaporated under vacuum with a dry ice trap. The white crystals (8.6 g 96.5%) of biguanide diperchlorate were dried under vacuum over P 2
O 5 and KOH. Concentration of a saturated ethyl acetate/acetonitrile solution gave crystals, mp 217°-219° C. |
Interesting how the biguanide is added as a solid mass.
This makes me wonder if the same could be done with hexamine to maybe improve yields.
Funny how reading the patent it looks like biguanid diperchlorate Seems quite a good explosive in terms of stability and easy prep with good yields.

What a fine day for chemistry this is.

That looks interesting, didn't see it in PATR. I know guanidine perchlorate is very powerful and easily initiated.

Are you sure this reaction works ?

Hi, Deus.
I am aware that the YouTube channel "Explosions&Fire" has recently made a video discussing and testing HDP. Check it out, there's some good
footage there if you're interested.
Cheers!~

Hey Tetra, you do realize DeusExMachina posted this in 2002 . I think the
ScienceMadness forum has some of the longest-running threads on the net.

CHP
If you have NH4ClO4 you can making no HDP hexamine diperchlorate, but directly CHP. Copper hexamine perchlorate. VoD est. 7500m/s in1.8g cm3. Low
friction, stabile in time, burning on air only. Ideal for filling detonator as monomaterial. Details on Liptakov channel.

Liptakov do you have any idea how long a detonator with this stuff can be stored?
Tacp cant very long... is CHP any better?
I mean it is fascinating stuff, but since you got system Berta to work with ETN, why not use this?
Much easier to make and to source the raw materials.

system Berta
Q1: Storage detonator CHP, 90 days by 20 Celsius. Same working power. Confirmed.
Q2 : CHP is soft material with low sensitive friction than crystals TACP. His DDT is better. Has the zero OB. Thus, much advantages against TACP.
Q3 : Maybe I am not understand your question. What should be easily? If you will have NH4ClO4, is possible making TACP on the stump in the wood. And
CHP also on stump on some piece metal plate. With hexamine fire and reagent. 2 in 1. Without el. power supply, cooling, without concentrate acids,
measurement, weighing, neutralisation, purification, etc.
Berta not working with ETN. But ETN + Al + NC . It are next processed. And now you can put the question again. What is easier ?

I second LL TACP is much easier than ETN, and lower sensativity. How can it not be stored long?

System Berta -- with CHP -- is conceived, destined for safety initiation on the amateur field. Easy, cheap, quick, best safety against others type
detonators. But Berta -- with CHP--Not for army with 10 years storage. What happens with 2 year old CHP detonator? Only it, that will be deflagrate
instead detonation. What happens with 2 year old professional factory ammonium nitrate emulsion? Will be not detonate. And yet they cheerfully sold
worldwide.

copper hexamine perchlorate
Details about preparation of copper hexamine perchlorate (CHP) was necessary deleted from YT but, according next research is clearly, that mixture ETN
+ CHP is possible use and it in almost any ratios. For example 20% ETN + 80% CHP or 85% ETN + 15% CHP. Running always, full strenght. With 80% ETN is
brisance of course bigger. Stability 90 days confirmed without changes of properties. Used was 95 days old powder from glass jar and filling before
test. 300mg pressed on 100 Kg/ dia 6mm and 200mg pressed on 5 Kg. Insert Bickford fuse. Detonator long 40 mm, wall 1 mm from soft Copper, Cu tube 6/8
mm. If you have ammonium perchlorate, you not need look any primary substance, which trashed the fingers. ......LL......
