Brief Overview
Monoammonium phosphate is formed with a solution of phosphoric acid and ammonia solution. Monoammonium phosphate, also known as ammonium dihydrogen phosphate, is widely used in food and fertilizer industries. Monoammonium phosphate has a tetragonal crystal prism structure. As a result of its crystal structure, ammonium dihydrogen phosphate is widely used in the optical industry. Monoammonium phosphate usually contains P2O5 (52%) and ammoniacal nitrogen (11%).
Manufacturing Process
Monoammonium phosphate is commercially produced by the reaction between ammonia and phosphoric acid of a 1:1 ratio, producing the resulting slurry of monoammonium phosphate. Monoammonium phosphates are then solidified in the granulator. Monoammonium phosphate can also be produced by the reacting 1:1 ratio of ammonia and phosphoric acid in a pipe cross reactor where the reaction generates heat to evaporate water and solidify the monoammonium phosphate product.
