Procedure

Sodium ammonium phosphate and ammonium chloride are prepared from an ammonium phosphate (e.g., diammonium phosphate) and sodium chloride in water. The crystallization of sodium ammonium phosphate may take place between -10° C. to 40° C. Using the present invention, technical grade sodium ammonium phosphate and ammonium chloride can be produced from fertilizer grade diammonium phosphate.

Workup

  1. customThe crystallization of sodium ammonium phosphate
  2. custombetween -10° C. to 40° C
