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 grams of sulfur and 7.5 g. of

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 soln. 1 and allow to cool.

5. Filter the soln. 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 soln. 3.

7. Slowly and drop by drop add conc. sulfuric acid to soln. 3 until the soln. turns

orange-brown.

8. Add to the orange-brown soln. 7.5 grams of sulfuric acid.

9. In 2nd beaker dissolve 5.4 grams of potassium or sodium nitrite in 240 ml of water.

Name it soln. 4.

10. Soln. 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.

SILVER ACETYLIDE

Synonyms: Double Salts

FORMULA:

Ag2C2 * AgNO3

VoD:

8

About 3600 m/s @ 5,38

EQUIVALENCE:

1.8 grams are needed for a #8 cap

SENSITIVITY:

not light sensitive, moderately friction sensitive, burns violently, may detonate in small

amounts.

DRAWBACKS:

not very powerful

COMPATIBILITY:

Can be mixed with most high explosives.

Avoid contact with copper and brass.

ADDITIONAL INFORMATION:

First prepared by the Swiss chemist Dr. Alfred Stettbacher.

Caps loaded with double salts are stable and have a long storage life.

PREPARATION:

Chemicals:

nitric acid (70%)

silver dime or equivalent silver metal

acetylene /calcium carbide + water/

alcohol

Materials:

2 test tubes 50 ml

glass beaker

filter paper

MANUFACTURE:

1. Fill a test tube with 18 ml of 70 % HNO3 ,

add a silver dime or equivalent silver metal in the acid.

2. If the silver does not dissolve completely, heat the acid carefully until it does.

NOTE: The red-brown gas given off by this reaction ( NO2) is highly toxic and should

be avoided.

A green solution should remain.

3. Heat the green liquid in a water bath until crystals form.
