Bis(2-ethylhexyl) terephthalate - Wikipedia

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.

Dioctyl terephthalate (DOTP) is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colourless liquid with a slight odour, which is insoluble in water. Dioctyl terephthalate is a very important phthalate-free plasticizer for PVC, preferred over low-chain and ortho-phthalate plasticizers as it is considered a safer alternative due

The quantification of di©octyl terephthalate and calcium carbonate in polyvinyl chloride using Fourier transform©infrared and Raman

1 INTRODUCTION Polyvinyl chloride (PVC) is the third most used polymer globally, due to its versatility and low production costs. 1 PVC compounds are used in many applications, including building and construction, medical devices, and cables. 2 Testing of any PVC product is typically completed during development, production (quality control [QC]), use (by customers of the end-product), and at

Alcoholysis of poly(ethylene terephthalate) to produce dioctyl terephthalate with sub- and super-critical isooctyl alcohol - ScienceDirect

The main liquid product of alcoholysis is DOTP and the DOTP is an important intermediate product which will decompose to produce crystal solid of terephthalic acid (TPA). As for the super-critical 2-EH, although the degradation rate of PET is very fast, the decomposition of DOTP is also very fast, thus, the sub-critical alcoholysis is advantageous to obtain 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.

The thermophilic phase accounted for 76% of the 98% overall DOTP removal. ? The thermophilic phase had the highest specific degradation rate of 0.149 day ?1. High DOTP concentration did not notably affect the bacterial community. ? Firmicutes were the most dominant in DOTP degradation by food waste composting.
