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.
A comparative study on the impact of phthalate esters on soil
In this study, an isothermal microcalorimetric technique was used to demonstrate the impact of dimethyl phthalate (DMP), di-n-octyl phthalate (DOP) and diethyl phthalate (DEP) on soil microbial activity. The effect of these phthalate esters (≤100 μg g soil) follows the order: DEP > DMP > DOP
5 Most important facts about Dioctyl phthalate (DOP) - Ideh
Dioctyl phthalate (DOP), also known as diethylhexyl phthalate (DEHP), is an organic compound with the molecular formula C6H4 (CO2C8H17). Dioctyl phthalate, characterized by its molecular weight, high boiling point, and low vapor pressure, is one of the most widely used general emollients.
- 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 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.
- 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.
