Abstract

The carbonyl compounds 5,6-carbonyl-ascorbic acid and 5,6-carbonyl-erythorbic acid been found useful for the preparation of explosive and propellant materials by admixing them with nitrate-containing oxidation agents and optionally further ingredients.

Claims

1. An explosive and propellant composition which comprises an admixture of 5,6-carbonyl-ascorbic acid or 5,6-carbonyl-erythorbic acid and a nitrate-containing oxidation agent.

2. A composition according to claim 1, wherein the nitrate-containing oxidation agent is an alkali or alkaline earth metal nitrate.

3. A composition according to claim 2, in which the nitrate-containing oxidation agent is an alkali metal nitrate.

4. A composition according to claim 3, in which the nitrate-containing oxidation agent is potassium nirate.

5. A composition according to claim 1, in which the nitrate-containing oxidation agent is ammonium nitrate.

6. A composition according to claim 1, wherein the weight ratio nitrate-containing oxidation agent to carbonyl compound is between about 40:

60 and about 80;
