Technical Document

Brief Overview
Trisodium phosphate appears as a white granular solid with a chemical formula of Na3PO4. It is highly soluble in water and is widely used in several applications, such as cleaning agents, lubricants, and food additives.
Manufacturing Process
Trisodium phosphate is produced through a neutralization reaction between sodium hydroxide and disodium phosphate, which is produced using sodium carbonate and phosphoric acid.
Na2CO3 + H3PO4 → Na2HPO4 + CO2+ H2O
Na2HPO4 + NaOH → Na3PO4 + H2O
