3,3’-Dinitro-4,4’-azoxyfurazan (DNAF) Explosive velocitu 9.800m/s, Great explosive.
Synthesised:
-----First you need to do DAAF before doing DNAF
The literature methods for DAAF oxidation to DNAF requires ammonium persulphate[18,19] or sodium persulphate[8], with hydrogen peroxide and sulphuric
acid, yield was 60%. DNAF can also be formed in by direct oxidation of 3,3’-diamino-4,4’-azofurazan or DAF, but with reduced yield (15% & 4%
respectively[18]).
3,3’-Dinitro-4,4’-azoxyfurazan: Into a 250ml conical beaker was added 27.5g 50% hydrogen peroxide diluted with 17.5ml water it was then chilled to
5°C. 30g ammonium persulphate was then dissolved into the peroxide solution and left to cool in the freezer. Another solution was made by dissolving
2.5g DAAF into 32g 98% sulphuric acid and was slowly added to the cooled peroxide solution maintaining the temperature below 20°C, on addition the
DAAF precipitated as a very fine orange suspension. The beaker was then placed in an oil bath heated to 40°C and stirred by use of a drill press
(figure 13). Good stirring must be used to churn the foam that is created during the oxidation. This was maintained for 8 hours whereby the orange
solution turned bright yellow. The solution was then drowned in 200ml ice cold water and filtered, flushed with more water then dissolved into 150ml
dichloromethane, the DCM solution was then washed with dilute sodium bicarbonate/water solution. The Yellow DCM solution was then separated and
evaporated to yield yellow crystals of DNAF (figure 13). Yield was 1.3g (40%).
Synthesys DAAF
DAAF is formed by the oxidation of DAF by a mixture of hydrogen peroxide and sulphuric acid[9].
3,3’-Diamino-4,4’-azoxyfurazan: Into 15g 50% hydrogen peroxide was added 10g crushed ice, then 14g sulphuric acid was dripped in maintaining
temperature below 20°C. This solution was then poured over 2.5g diaminofurazan in a 80ml beaker. The suspension was stirred by use of a drill press,
whereby the DAF went into solution imparting a green colour from the formed, soluble nitroso compound. Within an hour the green colour gave way to
orange due to a fine precipitate of DAAF (figure 11). The solution was stirred for 9 hours then left for a further 15 for a total of 24 hours. The
mixture was then diluted with an equal volume of water, filtered to recover a fine orange crystals (figure 12), washed with 200ml of cold water and
dried. Yield after bottling was 1.5g (57%).

This thread is not necessary seeing how a member of this forum has made this compound and dedicated a thread to it!

Looks like copy pasta.

Any Idea to do keto-RDX?
2-oxo-1,3,5-trinitro-1,3,5-triazacyclohexane is much more powerful than HMX...

Yep, Copy Pasta would certainly be "strike one".
A standard UTFSE would be a classical "strike two".

DNAF is too sensitive for any use. And 9800 ms-1 is higher than it actually is. DDF is almost as much of a pain to make as octanitrocubane.
