Anhydrous sodium pyrophosphate is colorless transparent crystal or white powder. The relative density is 1.824, and the melting point is 880ºC. Soluble in water, insoluble in alcohol, its aqueous solution is alkaline, easy to weather, moisture absorption. It has a strong pH buffer and has certain chelating effect on metal ions. Anhydrous sodium pyrophosphate is mainly used as water softener, bleaching auxiliaries for printing and dyeing, wool degreaser, boiler descaling agent, metal ion chelating agent, dispersant, auxiliaries for printing and dyeing and fine bleaching of grass products. Synthetic detergent additives.
Used as a complexing agent for copper in electroplating solution. Used as a rust remover in machining. Preparation of wool bleaching aid and wool degreasing agent with insurance powder. Auxiliaries for bleaching, dyeing and finishing bleaching of plant fibers. Used for synthetic detergent as a washing aid. In the production of calcium hydrogen phosphate for toothpaste, adding an appropriate amount of sodium pyrophosphate to form colloids, which plays a stabilizing role. Used as dispersant and emulsifier in chemical production. Water treatment as water softening agent, boiler descaling agent. It is a raw material for producing other pyrophosphates.
As a quality improver, it can improve the complex metal ions, pH value and ionic strength of food, thereby improving the binding force and water retention of food. China's regulations can be used for dairy products, poultry and fish products, meat products, ice cream and instant noodles, the maximum use of 5.0g/kg; The maximum use in canned, fruit juice (flavored) drinks and vegetable protein drinks is 1.0g/kg. As a whitener used for compounding potato starch, the maximum usage is 0.025g/kg.
