Patent ID: 7662248

Claim:
A process for producing a gas generating agent, which comprises the following sequential steps: (a.) feeding at least two starting components including a nitrogen-containing compound fuel and basic copper nitrate oxidizing agent and stirring and mixing them in the presence of 10 to 60% by weight moisture which has an electrical conductance of not higher than 2 μS/cm and which is in the form of an aqueous solution, water, or water vapor to form a mixture, (b.) aging the mixture by heating it at a temperature of 35 to 50° C. for 8 hours or more so that an amount of moisture in the mixture of the starting compounds at the time of being transferred to the extrusion-molding step which follows is 10 to 20% by weight, (c.) extrusion-molding the mixture and cutting it, and (d.) drying it by a two-stage drying process which comprises placing it in a drying oven, then carrying out pre-drying at 20 to 40° C. and subsequently carrying out drying at 80 to 120° C., whereby an amount of moisture in the gas generating agent is reduced to 0.5% by weight or less.
