Gas-generative composition consisting essentially of ammonium perchlorate plus a chlorine scavenger and an organic fuel
First Claim
1. A gas-generative composition comprising:
- a) an amount of ammonium perchlorate;
b) at least one chlorine scavenger in an amount sufficient to combine with chlorine present in the amount of ammonium perchlorate; and
c) at least a stoichiometric amount of organic fuel for complete combustion.

Abstract
This invention relates to gas-generative compositions consisting essentially of ammonium perchlorate with a chlorine scavenger, such as strontium nitrate, barium nitrate, potassium nitrate, or lithium carbonate, the combination being present in an amount of about 30 to about 95% by weight, up to about 5% by weight of a binder, up to about 5% by weight of a burning rate catalyst, together with an organic fuel, such as guanidine nitrate. The fuel is in an amount complementary to the combined weight of ammonium perchlorate, burning rate catalyst, chlorine scavenger, and binder, at an oxidation ratio of 0.90 to 0.98. The invention also includes the method of inflating an inflatable device by generating gas employing the noted composition and a gas generator in which the gas-generative composition is that of the present invention.
