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. In this study, we prepared DOTP from the alcoholysis of polyethylen
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.
The quantification of di‐octyl terephthalate and calcium carbonate
We explored alternative analysis techniques, Fourier transform-infrared (FT-IR) and micro-Raman spectroscopy to quantify the main components within a plasticised PVC (pPVC) compound with dioctyl terephthalate (DOTP) plasticizer and calcium carbonate filler. This can reduce costs in the testing and development of new products up to 50%.

- What is DOTP Dioctyl terephthalate?
- TCC’s ChemFlexx DOTP Dioctyl terephthalate (bis (2-ethylhexyl) benzene-1,4-dicarboxylate), commonly abbreviated DOTP, is an organic compound with the formula C 6 H 4 (C 8 H 17 COO) 2. It is the most important of the phthlte-free plasticizers, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol.
- What is Dioctyl terephthalate?
- Dioctyl terephthalate is a colorless liquid with a viscous to oily viscosity. Its properties make it suitable as a plasticizer in products requiring high transparency, colorlessness, resistance and migration fastness. The faintly smelling compound is practically insoluble in water.
- 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.
- 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.
- Why does Dioctyl terephthalate float on water?
- On contact, dioctyl terephthalate floats on water due to its lower density. 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.
- 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.
