| 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.
