TSP Chemical

TSP chemical with the full name of trisodium phosphate, is also known as sodium phosphate tribasic. It is a white, granular or crystalline solid inorganic compound with the chemical formula of Na3PO4. In general, it usually contains two types, trisodium phosphate anhydrous with the formula of Na3PO4 and dodecahydrate trisodium phosphate tsp with the formula of Na3PO4• 12H2O. TSP powder is highly soluble in water and can produce an alkaline solution. Chemate can supply both the two type tsp chemical for using in food and various industrial fileds.

Types of TSP Chemical

In addition to the tsp anhydrous and tsp dodecahydrate we mentioned above, it can also be divided into industry grade and food grade depends on its uses. Industry grade tsp chemical can be dodecahydrate and anhydrous. And the food grade trisodium phosphate is usually dodecahydrate TSP. The melting point of dodecahydrate is 73.4℃, the relative density is 1.62. It is almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide and the PH value of 1% aqueous solution is 12.1. When heated to 55-65℃, it becomes decahydrate, heated to 60-100℃ into hexahydrate, heated to above 100℃ to become monohydrate. When heated to above 21℃, it becomes anhydrous.

  • In chemical industry, textile, printing and dyeing, papermaking, power generation and other industries, it is used as water softener and detergent, boiler antiscalant, water softener in paper dyeing, PH buffer for the production of adhesives for waxed paper, solid printing and dyeing colorant, mercerizing enhancer of fabric, anti-brittle agent of thread.
  • Used in the metallurgical industry for chemical degreasing and decontamination. Also used as an excellent accelerator in photographic developing solutions.
  • Used as tooth cleaner and detergent for bottle applicators, coagulant in rubber milk, syrup cleanser.
  • Phosphate chemicals play a role in quality improvement in food processing. For example, it can maintain the water holding capacity of the meat and enhance the binding strength in meat products, so as to reduce the loss of nutrients in the meat and preserve the tenderness of the meat. It is also used as an emulsifier, nutritional supplement in food processing. It is used as raw material to prepare edible alkaline water, also used in sugar refining and starch manufacturing.
  • Solid trisodium phosphate(TSP) is a strong alkali and weak acid salt, which has strong alkalinity and high solubility. With stable chemical properties, it can be stored for a long time. Adding TSP instead of NaOH in the spray water of the containment spray system can adjust the PH value of the spray liquid, effectively remove the iodine gas released into the containment from the leaked cooling water into the containment, and avoid the damage of strong alkali to the staff. It is easy to clean up after an accident.

Phosphoric acid can directly interact with sodium to form three sodium salts. When a hydrogen ion in the molecular formula of phosphoric acid is replaced by a metal sodium atom, the first sodium salt is formed, namely sodium dihydrogen phosphate NaH2PO4. When two hydrogen ions in the phosphate formula are replaced by two sodium metal atoms, a second sodium salt is formed, namely disodium hydrogen phosphate Na2HPO4. These two sodium salts are called acid salts because of the presence of hydrogen ions in the molecular formula. When the three hydrogen ions in the formula of phosphoric acid are completely replaced by three sodium atoms, a third type of sodium is generated called sodium orthophosphate, that is trisodium phosphate Na3PO4.

As food additive, trisodium phosphate has been widely used in food processing. There are international standards for this product, and the indicators are very strict, such as, the standards of JECFA, FCC. The food health and safety organization has relatively strict restrictions on some harmful impurities. In the rule of FCC, The index of arsenic is no more than 0.0003%, the fluoride is no more than 0.005%, the lead is no more than 0.0004%. Used as food additive, sodium phosphate tribasic is widely used in various food processing industries, which is directly related to human health. So it is necessary to control the quality and the content index of each substance of trisodium phosphate food grade.
