CAS 7320-34-5 K4P2O7 Tetrapotassium Pyrophosphate Water Treatment

Product Description:
 
Easily deliquescence, easily degradable water, the solution is alkaline, does not dissolve alcohol, it loses two molecules of crystal water when heated to 180℃, and completely loses water when it reaches 300℃. The solubility in 100g of water at 25°C is 187g. The pH of a 1% aqueous solution is 10.2. Potassium pyrophosphate has all the properties of other condensed phosphates.

Properties:
 
1. It will not decompose if used and stored according to specifications.
2. Dissolve 187g in 100g water at 25℃, which can chelate with alkaline earth metal and heavy metal ions. It is soluble in water but insoluble in ethanol. The aqueous solution is alkaline. The solubility in 100g of water at 25°C is 187g. The pH of a 1% aqueous solution is 10.2. Potassium pyrophosphate has all the properties of other condensed phosphates.
3. Both hygroscopicity and deliquescent are great. The solubility in 100g water is 187g (25°C). Insoluble in ethanol. The pH of a 1% aqueous solution is 10.2. There are two variants of α type (high-temperature type) and β type (low-temperature type). The β form is converted to the α form at 500°C. The pure aqueous solution is difficult to decompose when boiling, but it can be hydrolyzed when there are other acids or alkalis.

Application:
 
Used for cyanide-free electroplating, dyeing, refined clay, etc.;
1 Mainly used for non-cyanide electroplating, instead of sodium cyanide as a complexing agent for electroplating. It is also used as a pretreatment agent for electroplating and as a pyrophosphate electroplating solution. Preparation of detergent components for clothing, metal surface cleaning agents and bottle detergent components, additives for various cleaning agents. Used as a clay dispersant in the ceramic industry, as a dispersant and buffer for pigments and dyes. The bleaching and dyeing industry is used to remove a small amount of ferric ions in the water to improve the quality of bleaching and dyeing. Potassium pyrophosphate is also an excellent stabilizer for hydrogen peroxide.
2 Used as an emulsifier, texture improver, chelating agent in the food industry, and also used as a raw material for alkaline water for noodle products. It is often used in combination with other condensed phosphates. It is usually used to prevent struvite from canned aquatic products and prevent discoloration of canned fruits; increase the expansion of ice cream, the yield of ham and sausage, and the water holding capacity of ground fish; improve the taste of noodles and increase the yield Rate, prevent cheese aging, etc.
3. Potassium pyrophosphate can also be used as a complexing agent for alkaline electroless nickel plating and for preparing detergents. Pyrophosphate can also be used as a complexing agent for alkaline nickel plating.
