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. Bisphenol A is mainly used to produce various polymer materials such as polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin and unsaturated polyester resin, and can also be used to produce fine chemical products such as plasticisers, flame retardants, antioxidants, heat stabilisers, rubber antioxidants, pesticides and coatings. Bisphenol A 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, in which the preliminary treatment of wastewater in the auxiliary units and the waste gas treatment process are included within the dataset boundary, 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 reaction, crystallisation feeding, crystallisation purification, mother liquor and n-pentane distillation recovery, dephenolisation and residual oil recovery, tail gas and phenol water recovery, and waste gas and waste residual oil incineration.
Activity Description
The production activities of this product include reaction, crystallization feed, crystallization purification, mother liquor and n-pentane distillation recovery, dephenolization and residual oil recovery, tail gas and phenolic water recovery, waste gas and waste residual oil incineration and other processes.
Process Description
Bisphenol A has the chemical formula C15H16O2 and CAS number 80-05-7. It typically occurs as white needle-like crystals or flakes with a faint phenolic odor. Its melting point is approximately 158–159°C, its normal boiling point is approximately 360°C, and its density is approximately 1.20 g/cm³. Bisphenol A is poorly soluble in water and soluble in ethanol, diethyl ether, acetone, benzene, and dilute alkaline solutions. It is mainly used to produce polycarbonate and epoxy resins and is also used in polysulfone resins, unsaturated polyester resins, other polymeric materials, and fine chemical products.

Technology comment
The resin-catalyzed condensation of phenol and acetone is the predominant technology for bisphenol A production. The process is clean and produces a high-purity product, accounting for more than 90% of total bisphenol A production in China. This dataset represents that technology. Phenol and acetone are used as the principal raw materials and undergo catalytic condensation to form bisphenol A, which is then purified to obtain the finished product. Mother liquor and n-pentane are recovered by distillation and reused; phenol is recovered in the dephenolization unit; heavy residues from the residual-oil reactor are burned as fuel in the waste-oil furnace; and collected off-gas is also incinerated in that furnace. The principal reaction is: 2C6H6O + C3H6O = C15H16O2 + H2O.
