Abstract: |
|||
| In this invention, such fertilizers as ammonium dihydrogen phosphate or ammonium sulfate and potassium chloride are used as raw materials to produce potassium dihydrogen phosphate and potassium sulfate, as well as the fertilizer ammonium chloride as by-prod. During pron., the fertilizers (such as ammonium nitrate, potassium chloride and ammonium dihydrogen phosphate), industrial salt, and running water are used to prepare a cyclic soln. which then reacts cyclically with the potassium chloride fertilizer, ammonium dihydrogen phosphato or ammonium sulfate fertilizer, and sodium chloride to produce potassium dihydrogen phosphate or potassium sulfate, as well as ammonium chloride fertilizer as by-prod. | |||
