Dioctyl Phthalate (DOP) - Chemical Supplier Distributor Chemceed
Dioctyl Phthalate is one of the most widely used plasticizers in PVC due to its low cost. DOP is a general-purpose plasticizer and long-time industry standard known for its good stability to heat and ultraviolet light, and broad range of compatibility for use with PVC resins. Dioctyl Phthalate can also be used as dielectric and hydraulic fluids.
Dioctyl Phthalate (DOP) Plasticizer - Fengbai Group
Dioctyl phthalate DOP, an organic ester compound, is one of the most commonly used plasticizers. DOP plasticizer is a transparent oily liquid with no visible impurities in appearance, which is insoluble in water, soluble in most organic solvents such as ethanol, ether, mineral oil, etc. As the most widely used plasticizer in industry, DOP as
An investigation of plasticisers in 21st century value chains
Until 2015, the chemical substance di-2-ethylhexyl phthalate (DEHP) – also known as dioctyl phthalate (DOP) – was widely used. A LMW compound, it remains approved for use in medical devices across most jurisdictions – largely due to a lack of effective replacements.

- 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.
