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.
BASF begins production of Palatinol DOTP plasticizer at its
HOUSTON, TEXAS, July 18, 2017 – BASF started the production of Palatinol DOTP (dioctyl terephthalate), a general purpose plasticizer, at its Pasadena, Texas facility, with a nameplate capacity of 60,000 metric tons per year. The plant enables BASF to respond to the growing demand for non-ortho-phthalate plasticizers in North America, and strengthens its position as a reliable source for DOTP.

- 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 makes DOTP safer than other plasticizers?
- DOTP, Dioctyl Terephthalate (also abbreviated DEHT) is a PVC plasticizer that is considered safer than low-chain and ortho-phthalate plasticizers due to its excellent toxicological profile.
- What is DOTP commonly used for?
- DOTP, Dioctyl Terephthalate (also abbreviated DEHT) is a PVC plasticizer that is considered safer than low-chain and ortho-phthalate plasticizers due to its excellent toxicological profile. It is probably one of the most important phthalate-free plasticisers in the market.
- What are phthalate-free plasticizers?
- One of the most important phthalate-free plasticizers in the market is Dioctyl terephthalate (DOTP). It is the ester of terephthalic acid and 2-ethylhexanol. In the European plasticizer market, DOTP is one of the growing phthalate-free plasticizers due to European environmental restrictions.
- What are some of the molding processes DOTP is used in?
- Dioctyl Terephthalate, DOTP, is extensively used in applications like extrusion, calendaring, injection molding, rotational molding, dip molding, slush molding, coating and some ink applications.
