What is Sodium Phosphate Dibasic?

Sodium phosphate dibasic, also known as disodium phosphate, is commonly produced from mined phosphate rock. Our sodium phosphate dibasic is of high purity and utility. It is formulated using premium-grade chemicals, ensuring a product with exceptional purity and chemical stability. Sodium phosphate dibasic is available in both anhydrous (water-free) and hydrated forms, with the hydrated forms being more prevalent.


The manufacturing process of sodium phosphate dibasic involves the following steps: First, a clear solution is prepared by dissolving 1 part of sodium hydroxide in 3.125-10 parts of deionized water, based on weight ratio. Then, while stirring the solution, 1.4375 parts of phosphoric acid solution with an 85% mass concentration is added, carefully adjusting the pH of the solution to fall within the range of 8.2-8.6. The temperature is maintained at 60-70 degrees Celsius, and stirring of the solution continues for 15-25 minutes. The pH of the solution is monitored until it stabilizes without any significant changes. The solution is then filtered. The filtrate is cooled under continuous stirring to a temperature of 30-35 degrees Celsius, promoting the precipitation and crystallization of sodium phosphate dibasic.

In summary, sodium phosphate dibasic is derived from phosphate rock and is produced through a meticulous manufacturing process. Our sodium phosphate dibasic offers exceptional purity and stability. It is available in anhydrous and hydrated forms, and the production process involves precise measurements, pH adjustment, filtration, and controlled cooling to facilitate the crystallization of the compound.
