l preferably from about 0 1 to 3 0 mol l depending upon temperature effective temperatures range from about 0 u00b0 to 100 u00b0 c preferably from about 0 u00b0 to about 60 u00b0 c an effective amount of caustic moh where m is selected from li na and k is also conducted into reaction zone rz via line 12 where hydrolysis takes the caustic converts the ammonium ion from the ammonium perchlorate to ammonia gas also the m cation that is introduced into reaction zone rz via the caustic takes the place of the ammonium ion in solution with the formation of m perchlorate aqueous or solid caustic can be introduced to reaction zone rz the reaction zone rz may be heated to enhance the rate of ammonia gas generation and recovery as a result the addition of solid caustic to reaction zone rz is beneficial in that the exothermic heat of solution can be used to heat the reactor of reaction zone rz in this invention the processing of 45 4 kilograms of ammonium perchlorate requires 15 4 kilograms of sodium hydroxide for the generation of a stoichiometric mixture in reaction zone rz the hydrolysis reactor generates about 6 8 kilograms of additional water about 6 8 kilograms of ammonia and about 47 2 kilograms of sodium perchlorate next the recovered ammonia is used to produce hydrogen as previously mentioned reaction zone rz is one in which hydrolysis of ammonium perchlorate in the presence of a caustic generates a product stream comprised of gaseous.
