What is Di Sodium Phosphate 99%?

Di Sodium Phosphate 99% refers to a high-purity form of disodium phosphate, also known as disodium hydrogen phosphate or di-sodium phosphate. It indicates that the product has a minimum purity level of 99%. Disodium phosphate is a compound composed of sodium cations (Na+) and phosphate anions (HPO42-). It is commonly found as a white, crystalline powder that is highly soluble in water. The 99% purity specification implies that the product is predominantly composed of disodium phosphate, with minimal impurities or other substances present.

Disodium Phosphate 99% is produced using a method that avoids the use of organic solvents and ensures a high level of purity. The process involves reacting monosodium sulfate with a phosphate component, such as phosphate rock, dicalcium phosphate, or a combination of both, in the presence of phosphoric acid. This reaction takes place at a temperature ranging from 40 to 100 degrees Celsius. Once the solid is separated, the resulting filtrate undergoes two stages of neutralization. In the first stage, a calcium component, such as calcium carbonate, calcium hydroxide, or a mixture of both, is added, leading to the formation of dicalcium phosphate, which is then separated. In the second stage, the filtrate is further neutralized using an alkali sodium component, such as sodium hydroxide, sodium carbonate, sodium bicarbonate, or a mixture of these, at a pH level between 8.0 and 9.5. Finally, the pure disodium phosphate is obtained through crystallization from the resulting filtrate.
