초록

A novel compound, used for example, as a gas generating fuel, is defined as a compound having the structural formula of R3—R1—R2, wherein R1 is a urea group, R2 is a tetrazolyl group with a C—N bond to the urea group, and R3 may be defined as a non-tetrazolyl, triazolyl, heterocyclic, heterocyclic amine, aliphatic, aliphatic amine, aryl, alkyl, hydrogen, or nitrogen group linked to the free nitrogen on the urea group. A method of making the compound is also provided. A gas generating composition 12 containing the novel compound as a ...
