Abstract: |
|||
| A process for preparing nitrates includes dissolving ammonium nitrate in ammonia solution, reaction of the solution on excessive solid calcium lime under a certain Vacuum to obtain calcium nitrate and ammonium sulfate as by-product, reaction of calcium nitrate with sodium (zinc) sulfate, or sodium carbonate (or barium amide), separation, concentration crystallizing and drying to obtain sodium (zinc, or barium) nitrate. Its advantages are easy control, high reaction speed, high output, and less consumption of product. | |||
