Dioctyl terephthalate = 96 6422-86-2 - Sigma-Aldrich
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 di-octyl terephthalate (DOTP)?
- Di-Octyl Terephthalate (DOTP) is a versatile and environmentally friendly plasticizer widely used in various industries. 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.
- Why is DOTP a good material?
- Its molecular structure provides excellent thermal stability, low volatility, and resistance to migration, making it ideal for long-lasting products. The following are key properties of DOTP: Low Volatility: Ensures stability over time in PVC products. Excellent Durability: Resists degradation even in high-temperature environments.
- What is Dioctyl terephthalate used for?
- Dioctyl Terephthalate is primarily used as a plasticizer. 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.
- What are the properties of DOTP?
- The following are key properties of DOTP: Low Volatility: Ensures stability over time in PVC products. Excellent Durability: Resists degradation even in high-temperature environments. Eco-friendly: Free from phthalates, making it safer for humans and the environment.
- 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.
- Can you eat Dioctyl terephthalate?
- Dioctyl terephthalate is approved for contact with food. According to an assessment by the European Food Safety Authority from 2008, up to 1 mg dioctyl terephthalate per kg body weight can be ingested daily without having any effects on health. There are no known harmful effects of dioctyl terephthalate on nature.
