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.

Dioctyl terephthalate (DOTP) is a plasticizer that can be prepared by alcoholysis of polyethylene terephthalate (PET) with isooctyl alcohol. Application DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films.
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 DOTP (Dioctyl Terephthalate)?
- DOTP, Dioctyl Terephthalate (also abbreviated DEHT) is a PVC plasticizer. It is considered safer than other plasticizers due to its excellent toxicological profile and is one of the most important phthalate-free plasticizers in the market. It is the ester of terephthalic acid and 2-ethylhexanol.
- What is Dioctyl terephthalate?
- Dioctyl Terephthalate, also known as DOTP, is a non-phthalate containing plasticizer. It is used primarily as a plasticizer in PVC production. DOTP-based end products comply with environmental requirements such as 16P, ROHS and REACH regulation. It has no adverse effects on human health.
- 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 DOTP used for?
- DOTP is the plasticizer of choice for high-temperature resistant cables (e.g., 70°C class cables), and is widely used as a sheathing material for power transmission and communication cables due to its low volatility and high electrical insulation properties.
- Is DOTP a good replacement for DOP & DINP?
- It has no adverse effects on human health. DOTP can be used as a direct replacement for DOP and DINP in a range of applications due to its thermal resistance, excellent durability and transparency. DOTP is an excellent plasticizer in the production of PVC and its copolymers.
- What is a DOTP based end product?
- DOTP-based end products comply with environmental requirements such as 16P, ROHS and REACH regulation. It has no adverse effects on human health. DOTP can be used as a direct replacement for DOP and DINP in a range of applications due to its thermal resistance, excellent durability and transparency.
