Manufacturing method 3 – DDNP/Diazodinitrophenol

Manufacturing method 2 – DDNP/Diazodinitrophenol

Chemicals:

Sodium hydroxide

Picric acid

Sulfur

Sulfuric acid (conc.)

Potassium or sodium nitrite

Water

Materials:

4 x 500 ml glass beakers

2 x Glass stirring rod

Filter papers

Heating source

MANUFACTURE:

1. Mix in a beaker 90 ml warm water and 1.5 grams of sodium hydroxide until all

NaOH is dissolved.

2. Stir in carefully 9 grams of picric acid in the above solution. Name it solution 1.

3. In the second beaker fill 300 ml water. Stir in 7.5 g of Sulfur and 7.5 g of

Sodium Hydroxide/NaOH. Boil this solution over a heating source. After a few minutes of boiling, the solution turns red. Allow to cool. Name it solution 2.

4. Add solution 2, under stirring, in three portions to solution 1 and allow to cool.

5. Filter the solution through coffee filter. Small red crystals should form. Discard the liquid.

6. These red crystals are added to 180 ml of boiling water.

Filter hot. Discard the crystals collect in filter paper, and name the liquid solution 3.

7. Slowly and drop by drop add concentrated sulfuric acid to solution 3 until the solution turns orange-brown.

8. Add to the orange-brown solution 7.5 g of sulfuric acid.

9. In 2nd beaker dissolve 5.4 g of potassium or sodium nitrite in 240 ml of water. Name it solution 4.

10. Solution 4 is added in one portion to soln. 3 under well stirring.

11. Let mixture sit for ca 10 minutes. Filter the now brown solution (pure DDNP) through a paper. The crystals left are washed with 60 ml water. Let dry for 24 hours. DDNP is best stored with 25% water. Load moist in detonator.

Picric acid 6 g

Sodium Hydroxide 6 g (Lye – caustic soda)

Sulfur 5 g

Sulfuric acid 120 ml

Sodium nitrite (not nitrate)

Distilled water

Boiling water

Distilled ice water

Diazodinitrophenol is a greenish yellow to a brown crystal and is superior to fulminate as a detonating agent. To make it:

1. Dissolve 1 g of sodium hydroxide in 65 ml of distilled water

2. Then add 6 g of picric acid to the lye solution.

3. In another container put 10 ml of distilled water and add 5 g of Sulfur to the water.

4. Now add 5 g of sodium hydroxide to the sulfur/water. Boil this mixture until it turns bright red. Let the solution cool off.

5. Add the sulfur/lye to picric acid solution in four portions letting the picric solution cool down in between additions. Stir the solution while adding the sulfur/lye.

6. Let the mixture cool off then filter out the red particles.

7. Dissolve the red particles in 130 ml of boiling water. Filter the solution and discard any precipitate, save the solution.

8. Add 80% sulfuric acid to the solution drop by drop until it turns an orangebrown color then add 15 ml more sulfuric acid. Let the solution cool down to room temperature.

9. Dissolve 3.75 g of sodium nitrite (not nitrate) in 150 ml of distilled water.

10. Add the nitrite solution to the orange-brown solution all at once while stirring. Let the solution stand for 10 - 15 mins. The solution should be a brown color.

11. Filter out the particles of DDNP and wash them with 100 ml of distilled ice water. Store the DDNP under a small amount of water until use.
