• Uses: (1) It can be used as the water softener, detergent, boiler detergents, metal rust inhibitors, dyeing fixing agent, fluxing agent for enamel production, bleaching agent, leather degreaser agent and degumming agent etc. (2) It can be used as analytical reagents, water softener and metal cleaning agent. (3) It can be used as water softener, boiler cleaning agents and metal rust inhibitors. It can also be applied to paper, leather, photography and so on. (4) It can be used as the softener, detergent, boiler scale inhibitor, water softener for paper dyeing water softener, PH buffers of the adhesive for producing glossy paper, the fixing agent for textile printing, mercerized enhancer for fabric, tendering resistant agent for making thread in the chemical, textile printing paper dyeing, power generation and other industries. It can be used for chemical degreasing and decontamination, and can also be used as the metal corrosion resistance agent or rust inhibitor in metallurgical industry; fluxing agent and bleaching agent in enamel industry; degreasing agents and rawhide unglued agent in leather industry; favorable promoter for photographic developing solution; tooth cleaners and detergents for bottle;? coagulating agent for rubber latex; juice purification agents. (5) It can be used as water softener, photographic developer and detergents. (6) Phosphate has the effect of improving quality in food processing, for example, keep the water capacity in meat and improve adhesive force in order to reduce the loss of nutrients make the meat soft. It can be used as the emulsifier, nutritional supplement and quality improver In food processing. It is the raw material of making the buck. It can also be used for refining the sugar and making theα-starch. The detergents for the bottles and cans. Sodium phosphate tribasic dodecahydrate is often used in the formulation of various buffers.
• Production method: (1) Neutralization method: Diluting the food-grade phosphoric acid with deionized water to a certain concentration solution, then add the mixed liquor to a stirred reactor, add the food grade caustic soda solution to the reactor slowly to neutralize the reaction. Adjust the ratio of Na/P to 3.24~3.26. Purifying the solution with bleaching agent, removing heavy metal agent and removing arsenic agent, and then remove the impurities by filtration. After the cooling crystallization, centrifugal separation and drying of the filter liquor, the final product-trisodium phosphate 12-hydrate can be obtained. The reaction is H3PO4+3NaOH→Na3PO4+3H2O (2) WPA method: add some wash water to the phosphoric which can be obtained by the reaction of the phosphate rock with sulfuric acid and dilute the solution which the content of the pentoxied is 18%~20% . The mixed liquor was heated to 85 ℃, adding 30 to 35. B6 sodium carbonate solution slowly at the condition of stirring and make the pH of it at the range of 8~8.4. Then, adding mother liquid of trisodium phosphate to the reactor and make the content of phosphorus pentoxide in the solution is less than 12%. After Insulated for 15~20min, the solution is filtered, concentrated and evaporated to 24~25 ° Bé. Adding the liquid caustic soda to make sodium reserve ratio to 3.24~3.26. The refined phosphate 12-hydrate can be obtained after the cooling crystallization, centrifugal separation and drying of the solution. The reaction is Ca5F (PO4) 3 + 5H2SO4 + 10H2O → 3H3PO4 + 5CaSO4? 2H2O + HF H3PO4 + Na2CO3 → Na2HPO4 + H2O + CO2 ↑ Na2HPO4 + NaOH →-Na3PO4 + H2O Thermal phosphoric acid method: Adding the phosphoric acid into the reactor and neutralize the liquid caustic soda which is slowly added into the reactor under the condition of the stirring can get the trisodium phosphate. The refined phosphate 12-hydrate can be obtained after the cooling crystallization, centrifugal separation and drying of the solution. The reaction is H3PO4+3NaOH→Na3PO4+3H2O
• Description: Sodium phosphate tribasic dodecahydrate is also known as trisodium phospate or TSP. It is a highly soluble in water and widely used as a cleaning agent. The pH of a 1% solution is typically around 12, making this reagent sufficiently alkaline for saponification of grease and oils. In combination with surfactants, TSP is an excellent agent for cleaning everything from laundry to concrete driveways. This versatility and low manufacturing price made TSP the basis for a plethora of cleaning products sold in the mid-20th century. Trisodium phosphate is used in the isolation of mycobacteria, including culturing of tubercle bacilli. Has been used as a protein precipitant in certain applications and in co-precipitation and fractionization of nucleotides. May be used for the preservation of biologically active soil samples. Because of the alkaline pH, TSP disrupts cytoplasmic and outer membranes of Salmonella enterica cells making it useful in preventing the spread of bacteria. It is used in photographic developing, clarifying sugar, removing boiler scale, softening water and manufacturing of paper. They are added to many foods as an emulsifier to prevent oil separation. It can be utilized as a leavening agent. Some instances of these foods include the batter coating on breaded fish or chicken, and commercially baked cakes. Adding this item to food increases the shelf life of the food, maintaining the texture and visual aspect of the food.
