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.

There are increasing concerns over the traditional plasticizers like dioctyl phthalate (DOP) on its potential migration out of PVC compounds and release to the environment or human body. The concerns have caused the industry to move towards more eco-friendly plasticizers.
Hanwha Chemical Produces Next-generation Eco-friendly
Dioctyl terephthalate (DOTP) plasticizers are used as an alternative, but done so at the expense of product quality. The new eco-friendly plasticizer ECO-DEHCH from Hanwha, however, is not short on quality and it is safe for humans.

Nonphthalate plasticizers are not based on phthalic acid, and have a different chemical structure and toxicological profile. These include terephthalates (the most common is dioctyl terephthalate [DOTP]), epoxy, aliphatics, trimellitates, polymerics, phosphates, and others.

- What is Dioctyl terephthalate?
- 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
- How to prepare DOTP from the alcoholysis of polyethylene terephthalate (PET)?
- In this study, we prepared DOTP from the alcoholysis of polyethylene terephthalate (PET) by using 2-ethyl-1-hexanol (2-EH) as the solvent, and used choline chloride-based deep eutectic solvents (ChCl-based DESs) as the catalysts due to their cheapness, low toxicity and ease of preparation.
- Can CHCl-based des be used to prepare DOTP under mild conditions?
- This work confirmed that ChCl-based DESs are favorable for the degradation of PET to prepare DOTP under mild conditions, which can also be used for other polymer degradation strategies. Dioctyl terephthalate (DOTP) is a new kind of green and non-toxic plasticizer.
- What is a DOTP plasticizer?
- Its primary function is to enhance the flexibility, durability, and workability of polyvinyl chloride (PVC) products while offering several advantages over traditional phthalate-based plasticizers. DOTP is known for its excellent thermal stability, low volatility, and high plasticizing efficiency.
- What is DOTP used for?
- DOTP is known for its excellent thermal stability, low volatility, and high plasticizing efficiency, making it ideal for applications requiring stringent safety and regulatory compliance.DOTP finds extensive use in the production of flexible PVC products, including medical devices, toys, food packaging, and automotive interiors.
- What is the molar ratio of pet vs DOTP?
- Under the optimized conditions (ChCl/Zn (Ac) 2 1 : 1, 5 wt%, 180 °C, 60 min, PET : 2-EH 1 : 5 molar ratio), the conversion of PET and the yield of DOTP were 100% and 84.7%, respectively. Furthermore, the possible mechanism was proposed through density functional theory (DFT) calculations and experimental results.
