Abstract: |
|||
| The present invention features that potassium chloride and ammonium sulfate as material are pre-treated separately before conversion reaction into pre-treated high-temperature reaction liquids, which are then mixed, cooled and crystallized to separate potassium sulfate as main product; and after filtration, evaporation, is obtained potassium ammonium chloride as by product. The present invention reach a conversion rate of potassium chloride up to 70%. | |||
