Abstract:
     This invention uses fertilizers of ammonium nitrate, ammonium dihydrophosphate and ammonium sulfate to react with fertilizer of potassium oxide respectively to produce potassium nitrate, potassium dihydrophosphate and potassium sulfate. By the process of this invention, the production of potassium nitrate requires no evaporation procedure and low temp. condition, and by-product ammonium chloride may be produced at normal temp.; the yield of production of potassium dihydrophosphate is high while by-product ammonium chloride is produced at normal temp.; the high yield of potassium sulfate may be obtained with no ammonia circulation procedure, while by -product ammonium chloride is produced at normal temp..
