Abstract
Abstract A compound having the following formula: ##STR1## wherein R 1 is --N + H 3 as found in claim 1 and R 2 is either the same as F 1 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.
