Plasticizers - Chemical Economics Handbook (CEH) | S&P Global
Major phthalates include di (2- ethylhexyl)phthalate (DEHP), also known as dioctyl phthalate (DOP); diisononyl phthalate (DINP); diisodecyl phthalate (DIDP); and di (2-propylheptyl) phthalate (DPHP). Nonphthalate plasticizers are not based on phthalic acid, and have a different chemical structure and toxicological profile.
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]

Thermodynamics and kinetics of dioctyl phthalate synthesis
The synthesis of dioctyl phthalate (DOP) involves mono- (2-ethylhexyl) phthalate (MEHP) formation firstly by phthalic anhydride (PA) with 2-ethyl hexanol (2-EH) and further esterification between
Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.
- What is dioctyl phthalate (DOP)?
- Dioctyl phthalate (DOP) is used in substantial quantities in industry, primarily as a plasticiser for PVC and other polymers. One route to its production is via the esterification of 2-ethylhexanol (2EH) with phthalic anhydride (PA) using a homogeneous catalyst. The process can be carried out in batch reactors.
- What is the manufacturing method of dioctyl phthalate (DOP)?
- Manufacturing method of dioctyl phthalate (DOP) Dioctyl phthalate (DOP) is a common plasticizer widely used in plastics, rubber, paints, coatings and other fields. This article will introduce the manufacturing method of DOP. I. Raw material preparation The following raw materials are needed for the manufacture of DOP: phthalic anhydride, octanol.
- How is dioctyl phthalate made?
- II.Reaction Principle DOP is manufactured by the esterification reaction between phthalic anhydride and octanol to produce dioctyl phthalate and water. III. Process Flow
- What is octyl phthalate?
- Octyl phthalate Dioctyl phthalate is one of the most important plasticizer, mainly used in the processing of PVC resin and high polymers such as chemical resin, acetic acid resin, ABS resin, rubber and in the production of lacquer, dyestuff and dispersant.
- Which phthalate is used as a plasticizer?
- DEHP is the most common member of the class of phthalates, which are used as plasticizers. DOP is the diester of phthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid is soluble in oil, but not in water. Dioctyl Phthalate (DOP) is a plasticizer used in the production of flexible polyvinyl chloride (PVC) plastic.
- Is dioctyl phthalate soluble in water?
- Dioctyl phthalate (DOP) is a colorless viscous liquid, which is non-soluble in water; however, it is soluble in oil. Its chemical names include phthalic acid, Bis (2-ethylhexyl) ester, and diethylhexyl phthalate (DEHP). These are manufactured by the reaction of 2-ethylhexonal with phthalic anhydride in the presence of catalyst sulfuric acid.
