Food Grade and Industrial Grade Trisodium Phosphate

Food Grade and Industrial Grade Trisodium phosphate Product Overview The CAS number of trisodium phosphate is 7601-54-9. He can be seen as using the phosphoric acid H3PO4 as a parent, and using three metallic sodium atoms, Na, to completely replace the three hydrogen ions H+ contained in its molecular formula. product. Because phosphoric acid H3PO4 is a tribasic acid, it has 3 hydrogen ions that can be replaced by metal elements in its formula. Colorless to white needle crystal or crystalline powder, anhydrous or crystal water containing 1 to 12 molecules, odorless. The dodecahydrate has a melting point of 73.4°C. Soluble in water, insoluble in ethanol. The 1% aqueous solution has a pH of 11.5-12.1. Colorless needle-like hexagonal crystals. Soluble in water, insoluble in organic solvents; Relative density 1.62 (20°C); Melting point 73.3-76.7°C (Decomposition); Easy to weather in dry air, Loss of 12 crystal water at 100°C (Na3PO4). The aqueous solution is alkaline and has a certain degree of erosion on the skin.Uses: Used as water softener in metallurgy, chemical industry, textile, printing and dyeing, paper making, electromechanical and other industries. Boiler pipe cleaning and detergents; Metal rust inhibitors, desiccants for dye intermediates, and sugar and sugar scavengers. , Photographic developer, fabric mercerizing agent, rubber latex coagulant, dental cement; also has a certain application in pharmaceutical preparations.
