How is potassium dihydrogen phosphate made?
Potassium dihydrogen phosphate, KDP, is a compound that is used as a source of potassium and phosphorus in fertilizers and other applications. It is produced by reacting ammonia with phosphoric acid.
Potassium dihydrogen phosphate is manufactured using the following steps:
1. Ammonia gas (NH3) is passed through a scrubber to remove dust particles from the air.
2. The ammonia gas is warmed to about 150°C (300°F). At this temperature, NH3 condenses into liquid NH4OH (ammonium hydroxide).
3. The liquid NH4OH flows through a distillation column where it is heated to about 200°C (400°F). This causes some of the water in the liquid to evaporate into a vapor phase and leave behind a concentrated solution of ammonium hydroxide in liquid form.
4. The concentrated solution of ammonium hydroxide flows into a reactor where it reacts with phosphoric acid at high temperatures (about 300°C or 570°F) and pressures (up to 800 pounds per square inch [psi]). The reaction produces a mixture of compounds that includes potassium dihydrogen phosphate (KDP).

What does potassium dihydrogen phosphate do to the body?
The human body needs potassium for a variety of functions. It is an important electrolyte that helps regulate blood pressure and fluid balance in the body. Potassium also helps maintain normal muscle and nerve function, keeps heart rhythm steady, and supports the immune system. The recommended daily intake for adults is 4,700 milligrams (mg). Most people get enough potassium from their diets, but those who have certain medical conditions or take certain medications may need to take a supplement.
Potassium plays an important role in maintaining healthy blood pressure levels. It does this by helping regulate calcium flow into and out of cells, which affects how much sodium enters cells as well. When sodium levels go up, potassium levels go down; when sodium levels go down, potassium levels rise again. This process maintains normal sodium-potassium concentrations inside each cell in your body so they can function properly.
