Procedure

To produce 9.6-34-0 compound, phosphorous acid, ammonia and water are merely added to the reactor and mixed appropriately at the temperature and pH set forth previously. To produce 9.8-34-0 orthopolyphosphoric acid via a polymerization reactor, phosphorus acid, ammonia, and water are added to the reactor. Alternatively, premanufactured 10-34-0 ammonium phosphate, phosphorous acid, ammonia and water are all added to the reactor. However, using premanufactured 10-34-0 ammonium phosphate is not preferred since such use may result in some hydrolysis thereby adversely affecting product stability. To produce 8.8-29-0 compound solution, orthophosphoric acid, phosphorous acid, ammonia and water are added to the reactor. Alternatively, premanufactured 8-24-0 compound, phosphorous acid, ammonia and water are added to the reactor. The following is an example of commercial production:
