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.
CPSC Staff Statement on University of Cincinnati Report
Di(2-ethylhexyl) terephthalate (DEHT) is a U.S. EPA high production volume chemical, with production above 50 million pounds/year in the U.S. (SCENIHR, 2008). Because it can be used as a substitute for DEHP, and other regulated or restricted plasticizers, consumption volume is increasing.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Terephthalate Plasticizers Terephthalate esters, particularly di-2-ethylhexyl terephthalate, are the most popular replacements for DEHP. Their low cost and long history as commercial plasticizers are their most attractive features. Dialkyl terephthalates with sidechains containing more than 8 carbon atoms have limited compatibility with PVC.
Terephthalates - Plasticisers - Information Center
Terephthalates Terephthalates are esters of tere-phthalic acid such as the 1,4 benzenedicarboxilic acid ester known as DEHTP or DOTP which offers low temperature performance, better resistance to soapy water extraction and low volatility.

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.
- What is DEHT (Dioctyl 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 often generically referred to as octyl.
- What is a standard state of terephthalate?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 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.
- Is Dioctyl terephthalate harmful?
- There are no known harmful effects of dioctyl terephthalate on nature. Since the substance is hardly water-soluble and also tends to bind to soil particles, it is presumably hardly mobile in the environment. Ensure your supply of Dioctylterephthalate (DOTP), ideal for producing plastic packaging, shoe soles, and waterproof clothing.
- What products contain Dioctyl terephthalate?
- In particular, it replaces the plasticizer DEHP (DOP), which has fallen into disrepute due to health risks, for example in PVC products for the food sector such as the caps of plastic bottles. Products containing dioctyl terephthalate also include gaskets, pipes, conveyor belts, cable sleeves, waterproof clothing, shoe soles and floor coverings.
- What is terephthalate used for?
- It is used primarily as a plasticizer for polyvinyl chloride and other polymers. DEHT is manufactured by the esterification of terephthalic acid and 2-ethylhexanol. Dioctyl terephthalate (DOTP) is a plasticizer that can be prepared by alcoholysis of polyethylene terephthalate (PET) with isooctyl alcohol.
- How do you store Dioctyl terephthalate?
- Dioctyl terephthalate is stable during shipment, storage and use under normal pressure and temperature conditions. However, it should be stored away from light, dry and in the closed container in a well-ventilated place. Dioctyl terephthalate reacts with strong acids, bases and oxidizing agents. The compound is combustible, but difficult to ignite.
