1,5-diamino-1,3,3,5,7,7-hexaazidocyclotetraphosphazene.
An energetic composition comprising 1,5-diamino-1,3,3,5,7,7-hexaazidocyclotetraphosphazene.
A method of preparation of 1,5-diamino-1,3,3,5,7,7-hexaazidocyclotetraphosphazene, which method comprises the steps of:
- a. reacting a quantity of octachlorocyclotetraphosphazene with ammonium hydroxide in ether to produce isomers of diaminohexachlorocyclotetraphosphazene;
- b. isolating 1,5-diamino-1,3,3,5,7,7-hexachlorocyclotetraphosphazene from the reaction product of step (a);
- c. reacting the 1,5-diamino-1,3,3,5,7,7-hexachlorocyclotetraphosphazene with sodium azide in acetone to produce 1,5-diamino-1,3,3,5,7,7-hexaazidocyclotetraphosphazene.
