Abstract

FURTHER OXIDATION OF AMINE GROUPS ON DAAF RESULTS IN THE EXTREMELY POWERFUL EXPLOSIVE 3, 3’-DINITROAZOXYFURAZAN. DNAF’S EXPLOSIVE PROPERTIES RATE IT AS ONE OF THE MOSTPOWERFUL OF THE CONVENTIONAL EXPLOSIVES WITH EXCEEDINGLY HIGH VELOCITY OF DETONATION, VERY HIGH HEAT O FORMATION AND GOOD OXYGEN BALANCE. DNAF IS ALSO CASTABLE, MELTING AT 110-112OC AND BOILING AT 270°C [1]. THE LITERATURE METHODS FOR DAAF OXIDATION TO DNAF REQUIRE AMMONIUM PERSULPHATE [2] OR SODIUM PERSULPHATE [2]; 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 INTO A 250 ML CONICAL BEAKER WAS ADDED 27.5 G 50% HYDROGEN PEROXIDE DILUTED WITH 17.5 ML WATER. IT WAS THEN CHILLED TO 5OC.30 G AMMONIUM PERSULPHATE WAS THEN DISSOLVED INTO THE PEROXIDE SOLUTION AND LEFT TO COOL IN THE FREEZER. ANOTHER SOLUTION WAS MADE BY DISSOLVING 2.5 G DAAF INTO 32 G 98% SULPHURIC ACID AND WAS SLOWLY ADDED TO THE COOLED PEROXIDE SOLUTION WHILE MAINTAINING THE TEMPERATURE BELOW 20OC. 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. THIS WAS MAINTAINED FOR 8 HOURS, THE ORANGE SOLUTION TURNING BRIGHT YELLOW. THE SOLUTION WAS THEN DROWNED IN 200 ML 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. YIELD WAS 1.3 G (40%). THE DNAF WAS PRESSED INTO A DRINKING STRAW, TAPED TO A LEAD BLOCK, BURIED UNDER SAND AND DETONATED.
