Performance of dioctyl terephthalate concrete - ScienceDirect
Dioctyl terephthalate (DOTP) obtained from waste PET is an oily substance and is compatible with concrete raw materials, which can make it an attractive material to be used as building materials. For this reason, the performance of DOTP-reinforced concrete is important for determining the direction of waste PET disposal.

An investigation of plasticisers in 21st century value chains
There's a growing interest in non-orthophthalate and bio-based plasticisers including DOTP-based products. In 2015, Poland's Grupa Azoty announced that its Oxoviflex (DOTP) plasticiser met European standards for use in FCM, children's articles and medical devices. The company now has capacity for 82 ktpa of DOTP, its phthalates-free replacement.

Aminolysis of poly(ethylene terephthalate) waste with
Ionic liquid (IL) as cosolvent is a new way to accelerate polymer solvation degradation, and thus several common imidazole ILs have been studied as cosolvent to improve the alcoholysis of PET with isooctyl alcohol (2-EH) to produce dioctyl terephthalate (DOTP) at the reflux temperature (190～200 °C).
- What is Dioctyl terephthalate (DOTP)?
- Dioctyl terephthalate (DOTP) obtained from waste PET is an oily substance and is compatible with concrete raw materials, which can make it an attractive material to be used as building materials. For this reason, the performance of DOTP-reinforced concrete is important for determining the direction of waste PET disposal.
- How to optimize the production process of Dioctyl terephthalate (DOTP)?
- As a green plasticizer, the industrial production of dioctyl terephthalate (DOTP) is still facing the problem of high energy consumption. To optimize the production process and reactor, it is essential to understand the kinetic behavior of reaction system.
- What is Dioctyl terephthalate used for?
- The obtained dioctyl terephthalate by the alcoholysis is used as a plasticizer especially in order to generate the polyvinyl chloride. Polyethylene terephthalate is generally removed by means of adding it directly to the concrete mix for the construction material.
- 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.
- Is Dioctyl terephthalate a plasticizer?
- DOTP is a terephthalate plasticizer and has a very different structure from the orthophthalate esters such as dioctyl phthalate, diisodecyl phthalate, diisononyl phthalate, as can be seen in their structural formulas (Fig. 11.1 ). Figure 11.1. Dioctyl terephthalate structural chemical formula ( Liu et al., 2013 ).
- Does Dioctyl terephthalate increase electrical resistance of concrete?
- The results show that the electrical resistivity of concrete increased with the increasing amount of dioctyl terephthalate. The optimum dioctyl terephthalate mixed concrete grout has got 29.90-times higher electric resistance than the reference concrete grout.
