Production Technology
DSP 12H₂O is produced through the neutralization of phosphoric acid
with sodium carbonate or sodium hydroxide. The process includes
precise crystallization to obtain the dodecahydrate form, followed
by rigorous drying and quality control.
Theory
As a dibasic phosphate, DSP dissociates in water to provide HPO₄²⁻
ions, which act as a buffer to stabilize pH. Its hydrated structure
enhances its solubility and ensures stable chemical performance,
making it indispensable in many industrial and laboratory settings.
