Dioctyl phthalate (also known as DEHP or di-2-ethylhexyl phthalate) is a type of phthalate, which is a class of chemicals that are used as plasticizers to make plastics more flexible and durable. DEHP is commonly used in the manufacture of polyvinyl chloride (PVC) plastic products, such as pipes, wire and cable coatings, and inflatable products.
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.
Bis(2-ethylhexyl) phthalate
DEHP is the most common phthalate plasticizer in medical devices such as intravenous tubing and bags, IV catheters, nasogastric tubes, dialysis bags and tubing, blood bags and transfusion tubing, and air tubes. DEHP makes these plastics softer and more flexible and was first introduced in the 1940s in blood bags.
- 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 do you purify DOP & 2-eh?
- 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. The DOP is typically obtained as a clear, colorless liquid with a boiling point of around 385°C.
