Latest Patents

Ernest W. Sale holds a patent for the production of ammonium polyphosphate solutions. This patent describes a method where ammonium polyphosphate is produced in a pipe reactor. The process involves injecting a stream of ammonia countercurrent to superphosphoric acid, which is passed axially through the reaction zone. This method causes vigorous backmixing of the two reactants, yielding a melt of ammonium polyphosphate. The cooling of the sidewalls of the pipe reactor is crucial, as it forms a layer of ammonium polyphosphate melt that prevents the formation of insoluble scale on the reactor's interior. The resulting melt is then dissolved in recycled aqueous ammonium polyphosphate product solution and further diluted with water to create the final product solution. Additionally, minor amounts of urea can be added to improve stability and conversion rates.
