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. Phenyl alkylsulfonate can be used as a primary or auxiliary plasticiser, and is especially suitable for plasticising systems with requirements for environmental protection, safety and cost control; it is mainly applied in fields such as PVC product processing, polyurethane products, automobiles, coatings, personal care products, food packaging, soft sheets and footwear. Phenyl alkylsulfonate 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 chlorosulfonation, esterification, distillation refining and distillation concentration.
Activity Description
The production activities of this product include chlorosulfonation, esterification, distillation refining, distillation concentration and other processes.
Process Description
Phenyl alkylsulfonate, commonly known as petroleum ester T-50, is an environmentally preferable plasticizer produced by esterifying C12-C18 alkylsulfonic acids with phenol. It has no single fixed chemical formula; a commonly reported CAS number is 8006-24-4. At ambient temperature and pressure, it is a pale-yellow transparent oily liquid with no pronounced odor, low volatility, a pour point of no more than -10°C, and a flash point of at least 200°C. It is insoluble in water but miscible with most organic solvents, including toluene, ethanol, and esters, and is highly compatible with polyvinyl chloride (PVC), polyurethane (PU), natural rubber, and other polymers. It is chemically stable and resistant to hydrolysis, aging, and saponification, and provides plasticization, flame resistance, and impact resistance. It contains no phthalates and meets relevant environmental and safety requirements. It is mainly used as a primary or secondary plasticizer in PVC products, including products subject to child-safety requirements, and in polyurethane products. It is also used in automotive applications, coatings, personal-care products, food-contact packaging, flexible sheets, footwear, and other plasticizer systems requiring environmental performance, safety, and cost control.

Technology comment
Sulfonation method is the core mainstream technology for the production of alkyl phenyl sulfonate. Using paraffin oil, liquid chlorine and sulfur dioxide as raw materials, a sulfonylation reaction is performed to obtain alkylsulfonyl chloride, which is then esterified with phenol to produce alkylsulfonate phenyl ester. The process mainly includes the chlorosulfonic chemical section, the esterification section, the distillation and refining section and the evaporation and concentration section:
1. Chlorosulfonation section: First, use a vacuum pump to drop the sulfuric acid in the oleum tank into the paraffin oil in the metering tank through a closed pipe to oxidize the unsaturated bonds in it, and then put the paraffin oil into the sulfonation reaction kettle. Liquid and liquid sulfur dioxide enter the sulfonation reactor through their respective buffer tanks. The reacted liquid phase (paraffin oil, alkylsulfonyl chloride) enters the esterification reaction section, and the tail gas (hydrogen chloride, chlorine gas and sulfur dioxide) generated by the reaction enters the hydrochloric acid absorption section.
2. Esterification section: First add a certain amount of caustic soda solution to the esterification kettle, and then add a certain amount of phenol. The phenol and caustic soda are mixed to form a sodium phenolate solution, and then the liquid phase of the sulfonation reaction (paraffin oil, alkylsulfonyl chloride) is added dropwise to perform the esterification reaction. The reacted material is acid-adjusted to neutralize excess sodium hydroxide.
3. Distillation and refining section: The alkali-washed material contains a large amount of paraffin oil, so it needs to be distilled. The distilled material is oxidatively decolorized using sodium hypochlorite solution.
4. Distillation and concentration section: The wastewater generated by the tail gas treatment system, extraction system, and decolorization system contains a large amount of salt, which will bring great difficulty to subsequent wastewater treatment. Therefore, vacuum distillation is used for evaporation and concentration.
