Phthalates leaching from plastic food and pharmaceutical
Phthalates are often used as plasticizers in the production of plastic food contact materials (FCMs) and pharmaceutical contact materials (PCMs), and having in mind that they are not bound to...
Bis(2-ethylhexyl) phthalate
Di (2-ethylhexyl) phthalate is produced commercially by the reaction of excess 2-ethylhexanol with phthalic anhydride in the presence of an acid catalyst such as sulfuric acid or para -toluenesulfonic acid. It was first produced in commercial quantities in Japan around 1933 and in the United States in 1939. [7]
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.

phthalic anhydride and hydrogen phthalate. The principal mechanism of the thermal decomposition for DEHP is a cis elimination reaction13 even in the presence of PVC. It was Figure 2.

An investigation of plasticisers in 21st century value chains
But not all phthalates survived. Until 2015, the chemical substance di-2-ethylhexyl phthalate (DEHP) – also known as dioctyl phthalate (DOP) – was widely used. A L MW compound, it remains approved for use in me dical de vices across most juris dictions – largely due to a lack of effective replacements.
- 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.

- Is dioctyl phthalate soluble in water?
- It is insoluble in water and has a good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis. Dioctyl Phthalate is used in PVC, polyvinyl acetate, rubbers, cellulose plastics and polyurethane.
- 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 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.
- 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.
