Gas generant compositions containing salts of 5-nitrobarbituric acid, salts of nitroorotic acid, or 5-nitrouracil
First Claim
1. A composition comprising:
- A. from about 25% to about 75% by weight of a heterocyclic compound having the structure;
##STR4## wherein R is selected from the group consisting of hydrogen,--CO2 X, and--OX and X is a cation selected from metals of Group I-A of the Periodic Table (except sodium), calcium, strontium, or barium;
B. from about 25% to about 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of Group I-A of the Periodic Table (except sodium), calcium, strontium, or barium, said salt having an anion which is essentially free of carbon, hydrogen or halogens; and
C. from 0 to about 5% by weight of a binder.

Abstract
Automotive airbag gas generant formulation providing alternative to commercially used formulations containing sodium azide. The composition comprises from about 25% to about 75% by weight of a heterocyclic compound having the following structure: ##STR1## wherein R is selected from hydrogen,
--CO2 X, and
--OX
and X is a cation providing an anhydrous salt. The other principal ingredient of the composition is from about 25% to 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of Group I-A of the Periodic Table (except sodium), calcium, strontium, or barium, and an anion which is essentially free of carbon, hydrogen, or halogens. From about 0% to 2% of a binder can be added, if necessary. An automotive airbag inflator containing the composition and a method for generating gas comprising the step of igniting the composition stated above are also disclosed.
