is rated using a thermal dioctyl phthalate (DOP) test. The test dust for HEPA filters is mono-sized, 0.3 m diameter, DOP particles, generated by vaporization and c ondensation. Alternative aerosols can also be used as specified or required for given applications. A photometer measures the particle penetration of the HEPA
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 the autoignition temperature of dioctyl phthalate?
- autoignition temp. n20/D 1.486 (lit.) 384 °C (lit.) Looking for similar products?
- Visit Product Comparison Guide Dioctyl phthalate is a non-volatile solvent mainly used as a plasticizer for polymers such as polyvinyl chloride (PVC), polystyrene (PS) and polyisoprene (PI).
- Does phthalate inhibit transthyretin in human placental trophoblastic cells?
- To Di- (2-ethylhexyl) phthalate inhibits expression and internalization of transthyretin in human placental trophoblastic cells. During pregnancy, fetal thyroid hormones (THs) are dependent on maternal placental transport and their physiological level is crucial for normal fetal neurodevelopment.
- 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.
- What is DOP used for?
- Wire and cable insulation: DOP is used as a plasticizer in wire and cable insulation to make it flexible and resistant to heat and chemicals. Toys and children's products: DOP is used in the production of toys and children's products to make them soft and pliable. Source high-quality dioctyl phthalate for industrial and chemical applications.
