Technical Document

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.

Food Industry

Monoammonium phosphate is mainly used as a food additive, fermentation agent, and nourishment in the food industry. It is widely used as a leavening agent in food production. As a leavening agent, monoammonium phosphate promotes fermentation and enhances nutrition in baked food. Monoammonium phosphate is used in nutrition and foliar feeding for all plants and crops.

Agriculture Industry

Monoammonium phosphate is widely used in making effective organic complex fertilizers, compound fertilizers, and bulk blending fertilizers. Monoammonium phosphate is required to sustain healthy plant growth.

Other Applications

Monoammonium phosphate is used in ceramics, enamels, fireproofing applications, dry fire extinguisher powders, and fermentation processes.
