Physicochemical Property of Sodium tripolyphosphate powder

White powder. Easily soluble in water, its aqueous solution is alkaline.

Production methodprocess of Sodium tripolyphosphate powder

Sodium tripolyphosphate powder The traditional method of preparation is to neutralise the hot phosphoric acid with the mass fraction of H3PO4 of 75% in the suspension of soda ash to make the neutralisation slurry with Na/P of 5∶3, and keep the slurry at 70℃～90℃; after that the slurry will be sprayed into the polymerisation furnace to dehydrate at high temperature, and condense into Sodium tripolyphosphate at about 400℃. tripolyphosphate CAS 7758-29-4.
