- What is dioctyl phthalate (DOP)?
- Interested in this product?
- Dioctyl phthalate (DOP) is a colorless, odorless, and oily liquid organic compound that belongs to the phthalate family. It is one of the most commonly used plasticizers and is particularly well-suited for use in polyvinyl chloride (PVC) products.
- How is dioctyl phthalate made?
- Esterification: In the next step, phthalic anhydride is esterified with 2-ethylhexanol (2-EH) to produce dioctyl phthalate. This reaction is catalyzed by an acid catalyst, typically sulfuric acid. Purification: The resulting mixture of DOP and unreacted 2-EH is then purified by fractional distillation to separate the DOP from the 2-EH.
- What is phthalic anhydride (DOP) used for?
- DOP is also known for its low volatility and resistance to high temperatures, which makes it useful in applications such as cable insulation, automotive parts, and medical devices. Synthesis of Phthalic Anhydride: The first step in the manufacturing of DOP involves the synthesis of phthalic anhydride.
- How is phthalic anhydride made?
- Synthesis of Phthalic Anhydride: The first step in the manufacturing of DOP involves the synthesis of phthalic anhydride. Phthalic anhydride is produced by the oxidation of naphthalene or o-xylene with air. Esterification: In the next step, phthalic anhydride is esterified with 2-ethylhexanol (2-EH) to produce dioctyl phthalate.
