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 consumption end, and the transport service is calculated based on the transport situation of the product in the region. Trisodium phosphate is mainly used as a water softener, boiler cleaner, metal rust inhibitor, and in papermaking, leather making, photography and other fields; trisodium phosphate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy, waste and air emissions of the production process, and infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed based on stoichiometry and by merging data from multiple sources; the production activity of this product includes neutralization, concentration, crystallization, drying and other process steps.
Activity Description
The production activities of this product include neutralization, concentration, crystallization, drying and other processes.
Process Description
Trisodium phosphate has the chemical formula Na3PO4 and CAS number 7601-54-9. It is typically a colorless to white hygroscopic crystalline solid with a relative density of approximately 2.5. It is readily soluble in water, insoluble in ethanol, and forms a strongly alkaline aqueous solution. It decomposes on heating. Trisodium phosphate is mainly used as a water softener, boiler cleaner, and metal corrosion inhibitor, and is also used in papermaking, tanning, photography, and other applications.

Technology comment
The wet-process phosphoric acid neutralization method is an economical mainstream technology for the production of trisodium phosphate. It is produced by the neutralization reaction of low-cost wet-process phosphoric acid and soda ash. It accounts for more than 80% of the domestic industrial grade trisodium phosphate market. This data set represents this mainstream technology: trisodium phosphate is modeled as the product of the reaction of phosphoric acid and sodium hydroxide, involving the chemical reaction equation: 3NaOH + H3PO4 → Na3PO4 + 3H2O.
