Product description
Potassium pyrophosphate, also known as tetra-sodium pyrophosphate, is made from the melting of di-potassium phosphate which causing it loss of one water molecule.
At room temperature, it is as a white crystalline powder or granules and has a strong moisture absorption capability in air and is easily soluble in water but insoluble in ethanol.
Its aqueous solution is alkaline and has effect on inhibition of food spoilage and fermentation.
The pH of 1% aqueous solution is about 10.5.
At about 25 ℃, the solubility of potassium pyrophosphate in 100g of water is 187g.
Potassium pyrophosphate is hydrolyzed into potassium phosphate in acid or alkaline solution and can form a viscous-like slurry body when being mixed with water.
Potassium pyrophosphate is mostly used in combination with other condensed phosphates, such as for the preparation of adhesive of ham and sausage in the ratio of 10% potassium pyrophosphate, 10% sodium pyrophosphate, 30% potassium polyphosphate, 30% sodium polyphosphate and 20% sodium metaphosphate.
Potassium pyrophosphate is commonly used for preventing the generation of struvite in canned fish, preventing the discoloration of canned fruit, increasing the swelling degree of ice cream, the extracting amount of the raw materials of coffee as well as the yield of ham and sausage, enhancing the water holding capacity of fish, improving the taste and yield of noodles, and preventing the aging of cheese.
In order to strengthen and smooth the plating layer, the formulation of industrial production of the plating solution is often very complicated.
Potassium pyrophosphate is previously often applied to cyanide as the complexing agent cyanide for preparing plating solution. However, because of the high toxicity of CN-, it does severe harm to the health of electroplating worker.
Moreover, the discharge of CN-of sewage, waste gas also seriously contaminates the environment.
So it is currently mainly applied of non-cyanide plating with the complexing agent replacing cyanide being potassium pyrophosphate.
The potassium pyrophosphate has all the properties of other polymeric phosphate and is also similar with sodium pyrophosphate but with a larger solubility and being able to have chelation reaction with the metal ions in alkaline soil and heavy metal ion;
Potassium pyrophosphate can also form complex with the Ca2 +, Mg2 + in harden water thereby softening the hard water, improving washing ability as well as removing dirt.
Potassium pyrophosphate can also form a protective film in the surface of metals such as iron, lead, zinc, and aluminum; the pyrophosphate ion (P2O74-) has a strong dispersing capability on the fine and dispersive solids, thus promoting the homogeneous mixing of fine, trace substances.
High purity, low iron-type potassium pyrophosphate has a stable pH buffering capacity with ability of long-term maintenance of pH value of the solution.
