Abstract

A compound having the following formula: ##STR1## wherein R¹ is --N⁺ H₃ as found in claim 1 and R² is either the same as F¹ or hydrogen. "A" is an oxidizing anion, and X is selected to provide a neutral charge balance for the compound. A method of making a compound of the indicated structure from a compound of similar structure by an anion exchange process is also disclosed. Finally, propellant formulations incorporating the novel compounds of the present invention as fuels and oxidizers are disclosed.

Claims

A is an oxidizing anion useful to provide oxidizing capability in a propellant formulation.

5. A liquid propellant consisting essentially of:

A. from about 60% to about 85% by weight of hydroxylammonium nitrate;

B. from about 30% by weight of a compound according to claim 1; and
