Abstract
Liquid monopropellants for passive vehicle restraint systems (e.g., air bags) include an aqueous solution of a water-soluble oxidizer and a water-soluble organic fuel miscible with the oxidizer. The oxidizer is most preferably ammonium nitrate, hydrogen peroxide or nitric acid, while the fuel is a lower alcohol such as methanol, ethanol, propanol or glycerol. The liquid monopropellants will advantageously have an oxidation ratio (OR) of greater than about 0.90.

12. A liquid monopropellant for passive vehicle restraint systems which consists essentially of, based on total monopropellant weight:
-
(a) an ammonium nitrate, hydrogen peroxide and/or nitric acid oxidizer present in an amount between about 60 wt. % to about 75 wt. %;
