No. 12

METHYL NITRATE DYNAMITE

A moist explosive mixture can be made from sulfuric acid, nitric acid, and methyl alcohol. This explosive can be detonated with a blasting cap.



MATERIALS REQUIRED: SOURCES:
Sulfuric acid Clear battery acid boiled until white fumes appear
Nitric acid Field grade nitric acid (Section I, No. 4) or 90% conc. (sp. gr. of 1.48)
Methyl alcohol Methanol
Wood alcohol (not denatured alcohol)
Anti-freeze (non-permanent)
Eyedropper of syringe with glass tube
Large diameter glass (2 qt.) jar
Narrow glass jars (1 qt.)
Absorbent (fine sawdust, shredded paper, shredded cloth)
Cup
Pan (3 to 5 gallon)
Teaspoon
Wooden stick
Steel pipe with end cap
Water
Tray

 

PROCEDURE:

1.  Add 24 teaspoons of sulfuric acid to 16-1/2 teaspoons of nitric acid in the 2-quart jar.

  

CAUTION: Acid will burn skin and destroy clothing. If any is spilled, wash it away with a large quantity of water. Do not inhale fumes.

 

2. Place the jar in the pan (3 to 5 gallon) filled with cold water or a stream and allow to cool.

3. Rapidly swirl the jar to create a whirlpool in the liquid (without splashing) while keeping the bottom portion of the jar in the water.

4. While continually swirling, add to mixture, 1/2 teaspoon at a time, 13-1/2 teaspoons of methyl alcohol, allowing mixture to cool at least one minute between additions.

 

CAUTION: If there is a sudden increase in the amount of fumes produced, or if the solution suddenly turns much darker or begins to froth, dump solution in the water within 10 seconds. This will halt the reaction and prevent an accident.

 

5. After the final addition of methyl alcohol, swirl for another 0 to 45 seconds.

6. Carefully pour the solution into one of the narrow glass jars. Allow jar to stand in water for approximately 5 minutes until two layers separate.

7. With an eyedropper or syringe, remove top layer and carefully put into another narrow glass jar. This liquid is the explosive.

 

CAUTION: Explosive is shock sensitive.


8. Add an equal quantity of water to the explosive and swirl. Allow mixture to separate again as in step 6. the explosive is now the bottom layer.

9. Carefully remove the top layer with the eyedropper or syringe and discard.

10. Place one firmly-packed cup of absorbent in the tray.

11. While stirring with the wooden stick, slowly add explosive until the mass is very damp but not wet enough to drip. Explosive is ready to use.

 

Note: if the mixture becomes too wet, add more absorbent.

Note: If storage of explosive is required, store in a sealed container to prevent evaporation.

 

CAUTION: Do not handle liquid explosive allow to contact skin. If this happens, flush sway immediately with large quantity of water. Keep, sand or dirt out of mix.

 
HOW TO USE:

1. Spoon this mixture into an iron or steel pipe which has an end cap threaded on one end. If a pipe is not available, you may use a dry tin can or glass jar.

2. Insert blasting cap just beneath the surface of the explosive mix.

Note: Confining the open end of the container will add to the effectiveness of the explosive.
