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. Diisononyl phthalate, as a plasticizer, is mainly applied in fields such as PVC processing, rubber, coatings and adhesives, and fine chemicals, and is especially suitable for the production of plastic products with high requirements for heat resistance, migration resistance and environmental safety. Diisononyl 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 and the waste gas 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, dealcoholization, neutralization and water washing, stripping and drying, filtration, wastewater treatment and other process steps.
Activity Description
The production activities of this product include esterification, dealcoholization, neutralization and water washing, stripping and drying, filtration, wastewater treatment and other processes.
Process Description
The chemical formula of diisononyl phthalate (DINP for short) is C26H42O4, CAS number 28553-12-0. It is a colorless and transparent oily liquid at room temperature and pressure. It is almost odorless and has extremely low volatility. It has a freezing point of about -48°C and a boiling point of about 405°C. It has excellent low-temperature fluidity and heat resistance. Slightly soluble in water, easily soluble in most organic solvents such as ethanol, ether, toluene, and mineral oil. It has excellent compatibility with polymer materials such as polyvinyl chloride (PVC), synthetic rubber, and cellulose resins. It has stable chemical properties, is resistant to hydrolysis, aging, and extraction, and its plasticizer migration rate is much lower than that of short-chain phthalate ester products. Industrially, it is mainly used as a plasticizer in PVC processing and the rubber industry; it is also used in coatings, adhesives, and fine chemicals. It can also be used to prepare cold-resistant cable materials, building waterproofing materials, etc. It is especially suitable for plastic product production scenarios that have high requirements for heat resistance, migration resistance, and environmental safety.

Using isononyl alcohol and phthalic anhydride as raw materials, it includes esterification, dealcoholization, neutralization and water washing, stripping and drying, filtration, wastewater treatment and other processes:
1. Esterification: Under normal pressure, heating and the presence of concentrated sulfuric acid, esterification reaction occurs between phthalic anhydride and isononyl alcohol to generate diisononyl phthalate. During the reaction process, the water generated by the reaction is removed by heating to ensure the normal progress of the esterification reaction.
2. Neutralization: Add soda ash to neutralize the sulfuric acid and part of the monononyl phthalate in the feed liquid.
3. Dealcoholization: Remove nonanol and water from the ester through vacuum distillation.
4. Alcohol recovery: Through atmospheric pressure heating distillation, nonanol in alcohol-containing water sent from each process is recovered.
