ABSTRACT:
A one vessel process for manufacturing stable ammonium phosphate fertilizer utilizes a spray reactor in which phosphoric acid is reacted with ammonia to form ammonium phosphate. The ammoniation is conducted under conditions which form sufficient ammonium polyphosphate to stabilize the solution in the liquid condition. The liquid may be stored and transported without substantial solidification or crystalization so that the product may be subsequently used as an ammonium phosphate fertilizer.
