Diammonium hydrogenorthophosphate (diammonium phosphate)

CPC v2.1 Code: 34642

About diammonium hydrogenorthophosphate (diammonium phosphate)

cpc code 34642 covers the production of diammonium hydrogenorthophosphate, also known as diammonium phosphate (DAP). DAP is a widely used inorganic fertilizer that plays a crucial role in global agricultural production. As a key source of nitrogen and phosphorus, it is an essential input for farmers worldwide, contributing to improved crop yields and food security.

Production process

Diammonium phosphate is typically produced through a chemical reaction between phosphoric acid and ammonia. The process involves neutralizing phosphoric acid with ammonia, resulting in the formation of diammonium phosphate crystals. These crystals are then dried, granulated, and sometimes coated to improve their physical properties and storage characteristics.

Production inputs

The main inputs required for the production of diammonium phosphate include phosphoric acid, ammonia, and various processing aids such as granulation binders and coatings. Specialized equipment, such as reactors, dryers, and granulators, are also necessary for the manufacturing process. The availability and cost of these raw materials and equipment can significantly impact the overall production of 34642 (Diammonium hydrogenorthophosphate (diammonium phosphate)).

Production outputs

Diammonium phosphate is a widely consumed fertilizer, primarily used in agricultural applications to provide essential nutrients for plant growth. Its output is often consumed by 34611 Nitrogenous fertilizers, 34612 Phosphatic fertilizers, and 34613 Potassic fertilizers, as well as by farmers and agricultural producers directly.
