| | Sodium trimetaphosphate Usage And Synthesis |
| Chemical Properties | efflorescent; tricl-rhomb prisms [MER06] | | Uses | Pharmaceutic aid. | | Uses | Sodium Trimetaphosphate works as the crosslinking agent in the cross-linked amylase-resistant starch. | | Industrial uses | Sodium trimetaphosphate, Na3[P3O9], is the most stable compound of this group of reagents. The hydrated form of sodium trimetaphosphate contains 6 or 10 molecules of water of crystallization. Commercial production is obtained by heating NaPO3 at 525 °C. | | Safety Profile | Poison by intravenous route. Moderately toxic by intraperitoneal route. When heated to decomposition it emits toxic fumes of POx and Na2O. See also PHOSPHATES. | | Purification Methods | It is precipitated from an aqueous solution at 40o by adding EtOH. It is dried in air. |
