Bis(2-ethylhexyl) terephthalate
This colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications. Production [ edit]
Alcoholysis of polyethylene terephthalate to produce dioctyl
Dioctyl terephthalate (DOTP) is a new kind of green and non-toxic plasticizer. The traditional process to prepare DOTP is costly and complicated, thus it is very necessary to find an efficient and environmentally-friendly way to obtain DOTP. In this study, we prepared DOTP from the alcoholysis of polyethylen
The quantification of di‐octyl terephthalate and calcium carbonate
We explored alternative analysis techniques, Fourier transform-infrared (FT-IR) and micro-Raman spectroscopy to quantify the main components within a plasticised PVC (pPVC) compound with dioctyl terephthalate (DOTP) plasticizer and calcium carbonate filler. This can reduce costs in the testing and development of new products up to 50%.

- What is Dioctyl terephthalate (DOTP)?
- Visit Product Comparison Guide Dioctyl terephthalate (DOTP) is a plasticizer that can be prepared by alcoholysis of polyethylene terephthalate (PET) with isooctyl alcohol. DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films.
- What is DOTP used for?
- DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films. It may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.
- Does DOTP contain phthalates?
- DOTP does not contain phthalates, in line with the EU REACH and other international regulations on the restriction of hazardous substances, safer for human beings and the environment, especially for food packaging, medical devices and other sensitive areas.
- What is the difference between a plasticizer DOP and a DOTP?
- Compared with the traditional plasticizer DOP, DOTP has less volatility loss and higher stability in long-term use, reducing material aging problems caused by plasticizer migration. High volume resistivity (up to 1×10⁹Ω-m or more), especially suitable for wire and cable insulation materials to ensure electrical safety.
- What is the hydrolysis of Di 2 ethylhexyl terephthalate?
- The hydrolysis of di (2-ethylhexyl) terephthalate (DEHT) and di (2-ethylhexyl) phthalate (DEHP) were studied using rat gut homogenate fractions in vitro. Both isomers were hydrolysed by the intestinal fraction; however, DEHP was hydrolysed to 2-ethylhexanol (2-EH) and mono (2-ethylhexyl) phthalate (MEHP) in
