    摘要： A method of thermally disposing a binder containing explosive that reduces the possibility of an unplanned detonation and also allows for the control of pollution. It is particularly adapted for solid rocket propellants. The method comprises cooling a binder containing explosive to a temperature below the Tg range of the binder, reducing the cooled explosive to a smaller size and burning the resultant explosive. Another aspect of this invention is directed to a method for reclaiming ammonium perchlorate from an explosive comprising ammonium perchlorate and a binder that reduces the possibility of an unplanned detonation. It is particularly adapted for solid rocket propellants. The method comprises cooling the explosive to a temperature below the Tg range of the binder, reducing the cooled explosive to a smaller size and chemically extracting the ammonium perchlorate.

    摘要： Liquid ammonia is maintained at the required operating conditions to efficiently and rapidly achieve propellant demilitarization including recovery of ammonia perchlorate (AP) for reuse, by an environmentally safe method to comminute and remove propellant from existing rocket motor hardware. The method is also applicable to both solid and ground composite propellant which includes scrap or waste propellant. A disclosed demilitarization unit employed in the ammonium perchlorate recovery method is comprised of a supply and high pressure spray system for liquid ammonia, an extraction system, oxidizer recovery system, and an ammonia recovery, drying,* and recycling system. The method is workable at ambient temperature since ammonia is liquified under its own vapor pressure at 114 psig; however, increased temperature further enhances the extraction efficiency of the system. Solubilized ammonium perchlorate is separated after a phase change takes place through a liquid-gas expansion nozzle which provides a direct method to "automatically precipitate and chemically grind" so to speak, the solid oxidizer AP particles to a predetermined, uniform size and configuration in accordance with established, solute purification techniques based on various temperature, pressure, and liquid nozzle spray conditions for particle size control when precipitated from a solvent. This method results in the rapid fall out of AP from liquid ammonia during the phase change or gasification stage since AP is insoluble in gaseous ammonia.

    摘要： Ammonium perchlorate is produced a process which comprises:(a) oxidizing a solution of chloric acid substantially free of ionic impurities,(b) introducing gaseous ammonia or an ammonium hydroxide solution into the crystallizing zone to produce ammonium perchlorate crystals, wherein the aqueous solution of perchloric acid and/or the ammonium hydroxide solution is in droplet form.High purity ammonium perchlorate crystals can now be produced directly which are free of transition metals, sulfates and phosphates, as well as substantially free of other ionic impurities including alkali metals, chlorate and chloride.
