Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. Potassium pyrophosphate is widely used in fields such as food, daily chemicals, electroplating, pharmaceuticals, ceramics, metal surface treatment and textiles; Potassium pyrophosphate is modelled as a pure substance; when modelling this substance the user needs to add a solvent of their choice in the model; the dataset contains the main raw and auxiliary materials, energy, waste and atmospheric emissions of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include neutralisation, filtration, drying, polycondensation, cooling, and crushing and screening. Sulfur is a by-product of this production process.
Activity Description
The production activities of this product include neutralization, filtration, drying, polycondensation, cooling, crushing and screening and other processes.
Process Description
The chemical formula of potassium pyrophosphate is K4P2O7, CAS number 7320-34-5. It is usually a white crystalline powder or granule, odorless, salty in taste, and easy to absorb moisture. It is easily soluble in water, the aqueous solution is weakly alkaline, and it is insoluble in organic solvents such as ethanol and ether. It has stable chemical properties and is not easily decomposed in the air, but it will be converted into potassium phosphate when heated to a higher temperature (about 900°C). It reacts with acids to generate phosphoric acid and corresponding potassium salts, and can form stable complexes with metal ions (such as calcium and magnesium ions). Industrially, it is widely used in the food industry (as a quality improver, used in the processing of meat products and aquatic products to improve elasticity and water retention, and can also be used as a moisture retaining agent, pH Conditioner), daily chemical industry (preparing toothpaste abrasives and detergents, using its complexing properties to remove calcium and magnesium ions in hard water, and enhancing the decontamination effect); also used in the electroplating industry (as a complexing agent for electroplating solutions to improve the quality of the coating), the pharmaceutical field (as a laxative ingredient), and can also be used as an auxiliary in ceramic manufacturing, metal surface treatment, and textile printing and dyeing.

Technology comment
This data set represents the mainstream technology: a neutralization reaction between phosphoric acid and potassium hydroxide produces dipotassium hydrogen phosphate, which is filtered to remove impurities and then dried. The dried material undergoes a polycondensation reaction at high temperature to generate potassium pyrophosphate, and is finally cooled, crushed, and screened to obtain the finished product. The main chemical reactions involved are: 2KOH + H3PO4 → K2HPO4 + 2H2O, 2K2HPO4 → K4P2O7 + H2O.
