How to make diamine hydrogen phosphate?

Slowly add concentrated ammonia water to the diammonium hydrogen phosphate solution for neutralization reaction, till the pH value is 14 to form the ammonium phosphate solution, and then cool, crystallize, centrifuge and dry it.

Using wet process phosphoric acid as raw material to produce diammonium hydrogen phosphate for feedstuff, the production process involves two steps of defluorination, three stages of ammoniation and pyrolysis of diammonium phosphate for feedstuff.
