Bis(2-ethylhexyl) phthalate, also known as dioctyl phthalate or DOP, is the most widely used plasticizer. In 2005, DOP accounted for approximately 85% and in 2017, for approximately 65% of all plasticizers used worldwide. DOP is miscible with many polymers. Its most common use is for PVC.
DOP is a colorless, almost odorless liquid with a high boiling point. It is insoluble in water and soluble in nonpolar solvents and oils. Its specific gravity is 0.99 g/mL, its melting point is -50 °C, and its boiling point is 385 °C.
DOP oil, which is the abbreviation of dioctyl phthalate, is an organic compound with the chemical formula C24H38O4, which is made from two main ingredients: diethylhexanol and phthalic anhydride. This compound is a chemical that is used as a phthalate ester and as one of the most common plasticizers in the plastics and coating industries. This product is one of the most important softeners of various types of PVC granule powder. Zafar Shimi Kimiagar Company is one of the leading manufacturers of DOP oil, which produces this product using high-quality raw materials. Zafar Shimi Kimiagar Company has been active in the field of plasticizer production for nearly a decade, offering the best and highest quality products at reasonable prices.

DOP oil is produced by combining the raw materials with catalysts, which are actually chemical reaction accelerators, in a stirred reactor at very high temperatures, and finally DOP oil is produced. The produced DOP oil is passed through a special filter and can be used after its temperature has been equilibrated. DOP oil is made by reacting excess 2-ethylhexanol or phthalic anhydride in the presence of an acidic catalyst such as sulfuric acid or para-toluene sulfonic acid. Because most 2-ethylhexanol is produced as a racemic mixture, commercially produced DOP oil is usually always racemic and consists of equal amounts of all three stereoisomers. PVC is widely used in the production of sewer pipes due to its low cost, chemical resistance, and ease of connection.
DOP oil has a softening effect and is used in various polymer industries. The most important applications of DOP oil include the following.
Plastics industry
DOP oil is used as a plasticizing agent in the plastics industry. By using this oil, polymers become flexible and transparent.
Paint and resin industry
DOP oil is used in the production of various paints and resins, leading to their high resistance and strength against heat.
Production of chemical products
DOP oil is one of the main materials used in the production of chemical products such as preservatives, derived oils and solvents.
Textile industry
DOP oil is used in the textile industry to soften fibers and make them more flexible.
Benefits of using DOP oil
The main industries that consume DOP in some form are:
Granulation
Cable manufacturing
Hose manufacturing
Paint manufacturing
Artificial leather manufacturers
Shoes
Adhesives
Toys
DOP is produced from the esterification of 2-ethylhexanol and phthalic anhydride in the presence of a catalyst.
The benefits of using dioctyl phthalate oil include the following:
Electrical and thermal resistance and resistance to ultraviolet rays
Low volatility and high efficiency
High flexibility at low temperatures
Affordable and inexpensive
Resistance to dehydration
Property of changing the physical and mechanical properties of polymers without changing their chemical structure
Excellent resistance to various conditions such as cold and climate changes
Improved flexibility and reduced deformation due to pressure
Resistant to abrasion and corrosion
Good electrical properties and softening
Increased resistance and creating a smooth surface
