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. Epoxidized soybean oil is mainly used as a plasticizer in scenarios with strict requirements on safety, environmental protection and low-temperature performance, including plastics processing, rubber, coatings and adhesives, medical devices, environmentally friendly cable compounds, floor leather, packaging films, etc. Epoxidized soybean oil 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, where the preliminary treatment of wastewater in the utility process and the waste gas treatment process are included within the dataset boundary, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes epoxidation, static separation, alkali washing, water washing, dehydration, pressure filtration and other process steps.
Activity Description
The production processes for this product include epoxidation, settling separation, alkali washing, water washing, dehydration, filter pressing, among others.
Process Description
Epoxidized soybean oil (ESBO for short) is an environmentally friendly plasticizer and stabilizer produced by epoxidation modification of soybean oil, with CAS number 8013-07-8. It is a light yellow to amber transparent oily liquid under normal temperature and pressure, with no obvious odor, extremely low volatility, and a freezing point of about -10°C. It is insoluble in water, easily soluble in organic solvents such as ethanol, ether, toluene, and esters, and has excellent compatibility with polymer materials such as polyvinyl chloride (PVC) and rubber. It has stable chemical properties, strong resistance to hydrolysis and aging, and possesses both plasticizing and thermal stability, and does not contain phthalate esters, complying with environmental protection and safety standards. Industrially, it is mainly used in plastic processing and the rubber industry; it is also used in coatings, adhesives, and medical equipment. It can also be used to prepare environmentally friendly cable materials, floor leather, packaging films, etc. It is especially suitable for scenarios that have strict requirements on safety, environmental protection, and low-temperature performance.

Technology comment
The peroxyacid method is the mainstream technology for epoxidized soybean oil production. The reaction is carried out in two steps. First, hydrogen peroxide and formic acid undergo peroxidation to generate performic acid. Then, performic acid reacts with carbon-carbon double bond components to produce epoxidized soybean oil, regenerating formic acid. The process is as follows: the refined oil is fed into the epoxidation kettle, heated with steam through a coil to 60°C, then heating is stopped and hydrogen peroxide and formic acid are added dropwise for the reaction. After the sample is qualified, the mixture is transferred via pipeline to a settling kettle, where it is left to stand for about 4 hours before water separation begins. The oil in the treatment kettle is first pumped into a 30% dilute alkali solution (sodium hydroxide), then passed through a mixer into an alkali washing centrifuge. The separated oil is then quantitatively mixed with hot water and enters a water washing centrifuge. The oil from the water washing centrifuge is sent to a drying kettle for dehydration. After dehydration is complete, the product is obtained by press filtration. Main chemical reaction equations: HCOOH + H2O2 → HCOOOH + H2O; soybean oil + 3HCOOOH → epoxidized soybean oil + 3HCOOH.
