Plasticizers: Synthesis of phthalate esters via FeCl3
Recently, sulfamic acid has been used to prepare dibutyl phthalate (4d) using about 6% catalyst loading by weight of the total reaction mixture either at 180 °C [13] or microwave conditions [14]. Dioctyl phthalate (DOP) is synthesized by using methanesulfonic acid as a catalyst at 160 °C [15].
Hanwha Solutions' phthalate-free plasticizer Eco-DEHCH offers
Given the growing need for observing the ESG mandate around the world, Hanwha Solutions' Chemical Division is seeking to completely halt its production of phthalate-based plasticizer DOP within 2025. The material is classified as hazardous material by Registration, Evaluation, Authorization and Restriction of Chemicals, EU regulations governing
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.
Plasticizers - Chemical Economics Handbook (CEH) | S&P Global
Phthalate esters, based on phthalic acid, are the main types of plasticizers used since they satisfy a broad range of processing and performance requirements, as well as a large number of markets. Major phthalates include di(2- ethylhexyl)phthalate (DEHP), also known as dioctyl phthalate (DOP); diisononyl phthalate (DINP); diisodecyl phthalate
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.
- What is dioctyl phthalate (DOP)?
- Dioctyl Phthalate (DOP) is a widely used industrial plasticizer, primarily utilized to enhance the flexibility and durability of polyvinyl chloride (PVC) products. It is a colorless, oily liquid known for its excellent compatibility with a variety of polymers.
- What is food grade dioctyl phthalate DOP?
- Food grade dioctyl phthalate DOP. Mainly used in the production of food packaging materials. But because it is easily extracted by fat, it is not suitable for fatty food packaging materials. Medical-grade dioctyl phthalate DOP.
- Is dioctyl phthalate soluble in water or oil?
- Dioctyl phthalate is soluble in oil but not water. The density of DOP is less than water, so it floats on the surface of water. Dioctyl phthalate accounts for more than 54% of the market share for plasticizers and is considered a high production volume chemical.
- Is DOP plasticizer soluble in water?
- DOP Plasticizer, or Dioctyl Phthalate, is a clear, colorless, and oily liquid commonly used to enhance the flexibility of plastics. It has a high boiling point and is insoluble in water but soluble in organic solvents like ethanol and ether. What is Dop Plasticizer?
- What phthalate is used in PVC?
- Di- (2-ethylhexyl) phthalate (DEHP, dioctyl phthalate, DOP) is the international standard PVC plasticizer, and the properties of other plasticizers are often measured against DEHP. Other general-purpose phthalates include diisononyl phthalate (DINP), di-isodecyl phthalate (DIDP), and di (2-propylheptyl) phthalate (DPHP).
- How is dioctyl phthalate synthesized?
- Dioctyl phthalate is synthesized by the esterification of phthalic anhydride with 2-ethylhexyl alcohol using a homogeneous acid catalyst such as concentrated sulfuric acid. This process is typically carried out in batch reactors under controlled temperature conditions for 16-20 hours.
