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
This colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure. It possesses very good plasticizing properties and may be used as a direct replacement for DEHP and DINP in many applications. Production [ edit]
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.
DOTP - SIBUR Int
SIBUR is producing DOTP from its own feedstock, to ensure seamless supplies and consistently high product quality. Dioctyl terephthalate (DOTP) is a phthalate-free polyvinyl chloride plasticizer. Unlike phthalate plasticizers, DOTP has no adverse effects on human health
5 Most important facts about Dioctyl phthalate (DOP)
The optimal slurry of dioctyl terephthalate (DOTP) has 29.90 times higher electrical resistance than the reference concrete slurry. In addition, 10% of dioctyl terephthalate (DOTP) concrete with thermal conductivity of less than 30.3% has an electrical resistance of more than 657.7%. To produce corrosion-resistant concrete mortar, dioctyl
- 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 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.
- What is DOTP used for?
- DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films. It may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.
- Are terephthalate plasticizers safe?
- DEHT is a general purpose plasticizer that is considered safer than ortho - phthalate plasticizers due to its reduced toxicity profile. The terephthalates exhibit none of the peroxisome proliferation of liver enzymes that some ortho - phthalates have shown in several studies.
- What are terephthalates used for?
- The terephthalates exhibit none of the peroxisome proliferation of liver enzymes that some ortho - phthalates have shown in several studies. It has uses in applications like extrusion, calendering, injection molding, rotational molding, dip molding, slush molding and coating.
