Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na 2 HPO 4, and monosodium phosphate, NaH 2 PO 4, under carefully controlled conditions. [2] 2 Na 2 HPO 4 + NaH 2 PO 4 → Na 5 P 3 O 10 + 2 H 2 O. In this way, approximately 2 million tons are produced annually. [3]
