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. Bis(2-propylheptyl) phthalate is mainly used as a plasticizer or modifier, in fields such as PVC processing, rubber, coatings, adhesives, plastic product modification and environmentally friendly materials. Bis(2-propylheptyl) phthalate 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, the waste gas treatment process and the solid waste incineration treatment process are included within the dataset boundary, and 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 esterification reaction, neutralization, water washing, stripping, filtration and other process steps.
Activity Description
The production activities of this product include esterification reaction, neutralization, water washing, stripping, filtration and other processes.
Process Description
Di(2-propylheptyl) phthalate (DPHP for short) has the chemical formula C28H46O4 and CAS number 53306-54-0. It is a colorless to light yellow transparent oily liquid under normal temperature and pressure. It has no obvious odor, extremely low volatility, a freezing point of about -47°C, and excellent low-temperature fluidity. It is insoluble in water, easily soluble in most organic solvents such as ethanol, ether, toluene, and esters, and has excellent compatibility with polymer materials such as polyvinyl chloride (PVC), polyurethane (PU), and cellulose. It is chemically stable, resistant to hydrolysis, aging, and extraction, and has excellent heat resistance and low-temperature flexibility. It is a high-performance general-purpose plasticizer. Industrially, it is mainly used in PVC processing and rubber industry; it is also used in coatings and adhesives, modification of plastic products, and can also be used to prepare environmentally friendly cable materials, toy plastics, etc.

Technology comment
Phthalic anhydride and 2-propylheptanol are used as raw materials for esterification:
1. Esterification: Phthalic anhydride, 2-propylheptanol, and tetrabutyl titanate are charged for the esterification reaction.
2. After vacuum dealcoholization, sodium hydroxide solution is added for neutralization.
3. Process water is added for washing.
4. Steam is introduced for stripping.
5. Activated carbon is added, and the product is obtained by filtration.
Main reaction equation: C8H4O3 + 2C10H22O → C28H46O4 + H2O.
