Diphoronepentaperoxide(DPPP)

The compound currently being discussed at the madscience forum raises
big interest: the starting materials acetone, conc. HCl and 30% H2O2
are (dirt-) cheap, and the substance performs an incredible vod of
about 9000m/s.

Other favourable properties, like better stability than AP, are listed
in the following german patent of the late 70`(translation by
Hoffmann-LaRoche):

German patent DE 1951660.

1969

Diphoronepentaperoxide C18H26O2(O2)5

Field of invention: the invention refers to an explosive which has
special properties that make it suitable especially for mining and as
well for military purposes.

Task: The invention wants to make blasting operations cheaper and
easier.

Solution: Following cheap substances are required for synthesis:

1 part conc. hydrochloric acid(HCl)
1 part acetone (CH3COCH3)
2 parts 30% hydrogen peroxide(H2O2)


Process of manufacture:

1 part of acetone are added to 1 part hydrochloric acid, through which
acetone polymerizes to phoron; then 2 parts of hydrogen peroxide are
added, through which two molecules of HCl bond with the two
C-double-bonds of the phoron.

In the course of the reaction free chlorine
develops, which bonds with 3 hydrogen atoms of the phoron to give 3
HCl(see drawing) and bonds itself with phoron.
Hydrogen peroxide causes the chlorine atoms to split off the phoron
and the peroxide itself bonds with the phoron.

Because of the fact, that one peroxy-bond stays half-opened, one also
open phoronperoxide adds to give diphoronpentaperoxide, which
precipitates from the solution in crystalline form.


Properties:

a) insoluble in water
b) still explosive when heavily contaminated
c) detonation velocity approx. 9000m/s
d) low detonation temperature approx. 200°C
e) does not develop smoke upon detonation, does not smell, no solid
residues.
f) ignition by fire, blasting cap or electric
g) does not decompose at long storage
h) yield of manufacturing process approx. 90%

I have to mention that this was already discussed a bit in the
medina-thread of high explosives, but stopped in the early stage and
deserves an own thread.
The madscience thread shows a lot of progress, on the synthesis of
phorone for instance.

------------------
I do not take the credit for this post, I just wanted to make sure
this exiting new energetic substance is opened up to as wide as
possible of an audience.
This message is posted on various forums too for exactly the same
purpose.

HOGWASH !!! it is only about 6,600m/s

Organic Peroxides are DANGEROUS, VERY

Interesting but still I don't understand a few things!
(CH3)2C=CH-CO-CH=C(CH3)2 + 2HCl gives the expected
(CH3)2CCl-CH2-CO-CH2-CCl(CH3)2 with respect to Markovnikov's rules!
But after Cl2 reacting on a alfa hydrogenated ceton in acidic media
should only give tetrachlorophoron and not pentachlorophoron; there is no
reason terminal CH3 to be attacked since the CH2 viccinal to the CO are
highly favourised! Even if CH3 terminal attack can be acheived; there is
no reason to stop at the pentachlorocompound (by attacking only two of
the four CH3); hexachlorocompound and heptachloro must be present aswel
in that case!
So more than certainly:
(CH3)2CCl-CHCl-CO-CHCl-CCl(CH3)2 is formed
Peroxydation of the above will produce:
(CH3)2CCl-CHCl-CO-CHCl-CCl(CH3)2 is also ((CH3)2CCl-CHCl-)2C=O
((CH3)2CCl-CHCl-)2C=O + 5HO-OH --> ((CH3)2C(OOH)-CH(OOH)-)2C(OOH)(OH) + 4
HCl
The above is indeed a pentaperoxyde and may be subjected to intra and exo
cyclisations!
I personnally doubt a single pure compound will be produced and it will
be an horrible mix of various molecules!

Also phorone is a resonant polyunsaturated compound; mixing it with a
peroxyde will for sure induce polymerisation...thus a polymer will be a
major byproduct!

Halogenation of CH3- is less easy than CH2Cl- itself less easy than
CHCl2-; then if halogenation of CH3 takes place perhalomethyl should be
found in significant amounts!

Final CONSIDERATION:
If the patent is true then there is no reason CH2Cl-CO-CH2Cl not to be a
precursor of HOOCH2-CO-CH2OOH and thus by reaction with H2O2 in HCl to
provide:
O-CH2
I C(OH)(OOH) that will cyclise into CTAP, CDAP and CTeAP kind of
ring but with a lot more oxygen, a lot
O-CH2
more stress, density, sensitivity and power!
(C3H4O4)2 --> 6CO + 2H2O + 2H2
(C3H4O4)3 --> 9CO + 3H2O + 3H2
(C3H4O4)4 --> 12CO + 4H2O + 4H2
