Abstract
In reacting ammonia with phosphoric acid in a reaction vessel to form a reaction mixture comprising ammonium phosphate, the reaction mixture is allowed to foam whereby there is formed a foaming reaction mixture comprising steam and ammonium phosphate and steam and ammonium phosphate are discharged from the reaction vessel through a common outlet. Preferably the ammoniation is carried out under pressure and the foam reaction mixture is discharged via a spray nozzle into a zone of lower pressure where water is evolved spontaneously, e.g. by flash evaporation as the product is sprayed, to give a solid particulate product.
