A process of forming a mixture of diammonium phosphate and triammonium phosphate by the reaction of phosphoric acid with gaseous ammonia in a spray column.

With the appropriate selection of the ammonia pressure and the phosphoric acid feed rate sprayed into the spray column, the amount of each of the diammonium phosphate and triammonium phosphate formed can be controlled.
