sodium tripolyphosphate is an inorganic substance with the chemical formula Na5P3O10. It is a kind of amorphous water soluble linear polyphosphate. It is widely used in food as a moisture store, quality enhancer, pH regulator and metal chelating agent.
What are the chemical properties of sodium tripolyphosphate?
What are the physical properties of sodium tripolyphosphate?
What are the applications of sodium tripolyphosphate in daily life?
1. Drinking capacity
sodium tripolyphosphate can be divided into high temperature type (Type I) and low temperature type (Type II) due to different formation temperatures. The difference is that the binding length and the binding angle of the two are different. Hydrate Na5P3O10 6H2O.
2. The ability to chelate metal ions
sodium tripolyphosphate forms complexes with Ca2+, Mg2+, Fe3+ and other metal ions dissolved in water to form soluble complexes.
3. Buffer effect
The aqueous sodium tripolyphosphate solution is weakly alkaline (the pH value of a 1%igen aqueous solution is approximately 9.7) and forms a suspension (similar to an emulsion) in the pH range of 4.3 to 14, ie a dispersion.
sodium tripolyphosphate can be divided into high temperature type (I type) and low temperature type (II type) due to different formation temperatures. The difference is that the binding length and the binding angle of the two are different. Hydrate Na₃P₃O₀ · 6H₂O.
Under the same conditions, type I hydration quickly generates high heat, and it is easy to cause agglomeration when dissolved in water. This is due to the presence of sodium ions in the type I structure. Strong affinity, in contrast Type II produces hexahydrate very slowly in water.
sodium tripolyphosphate can be used as detergent aid and can also be used in petroleum, metallurgy, mining, paper making, water treatment, etc. use. Mainly used as an adjuvant for synthetic detergents, as a soap synergist and to prevent precipitation and efflorescence.
sodium tripolyphosphate can have a strong emulsifying effect on lubricating oils and fats and can be used to adjust the pH value of buffer soap.
sodium tripolyphosphate can be used as water softener for industrial water Tanning agent ---Dyeing agent It is used as a dispersing agent in the production of suspensions in paints, kaolin, magnesium oxide, Calcium carbonate and other industries uses drilling mud dispersing agent It is used in paper industry as oil repellent.
In the food industry, sodium tripolyphosphate can be used as a quality enhancer and water retention agent for canned foods, fruit juice drinks, dairy products, soy milk, etc. use. and can also be used as plasticizer and thickener.
