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.
Hanwha Solutions' phthalate-free plasticizer Eco-DEHCH offers
Eco-DEHCH is one of the most recognized phthalate-free plasticizer developed by a research team at Hanwha Solutions’ Chemical Division, providing eco-friendly alternative for hazardous dioctyl phthalate (DOP) and less-harmful but less-effective terephthalate like dioctyl terephthalate (DOTP).
EcoFriendly Plasticizers IHS Chemical - IHS Markit
There are increasing concerns over the traditional plasticizers like dioctyl phthalate (DOP) on its potential migration out of PVC compounds and release to the environment or human body. The concerns have caused the industry to move towards more eco-friendly plasticizers.
Hanwha Chemical Produces Next-generation Eco-friendly
Dioctyl terephthalate (DOTP) plasticizers are used as an alternative, but done so at the expense of product quality. The new eco-friendly plasticizer ECO-DEHCH from Hanwha, however, is not short on quality and it is safe for humans.
Bis(2-ethylhexyl) terephthalate
It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl. 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.
- What is DOTP (Dioctyl Terephthalate)?
- DOTP, Dioctyl Terephthalate (also abbreviated DEHT) is a PVC plasticizer. It is considered safer than other plasticizers due to its excellent toxicological profile and is one of the most important phthalate-free plasticizers in the market. It is the ester of terephthalic acid and 2-ethylhexanol.
- Is DOTP (DEHT) eco-friendly?
- To fully understand the environmental impact of a particular product, the entire life cycle needs to be considered: without data to support the claim, saying DOTP (DEHT) is “eco-friendly” is not accurate. DOTP (DEHT) was developed in 1949 and patented in 1953 by ExxonMobil but never commercialized for a good reason.
- What is eco-dehch (diethylhexyl cyclohexane)?
- Hanwha Chemical is advancing into the next-generation eco-friendly plasticizer with the production of ECO-DEHCH (Diethylhexyl-cyclohexane), a phthalate-free premium plasticizer. At its plant located in the Ulsan Petrochemical Industry Complex, the annual production capacity is expected to be 15,000 tons.
- Where is phthalate-free plasticizer eco-dehch produced?
- Hanwha Solutions’ Chemical Division announced that it quadrupled annual production of phthalate-free plasticizer Eco-DEHCH. Up to 6.5 tons of it will be produced every year at a petrochemical industrial complex in the southeastern port city of Ulsan, South Korea.
- How does eco-dehch remove phthalate-inducing material?
- Adding hydrogen to DOTP plasticizer, Eco-DEHCH manages to remove phthalate-inducing material from its chemical structure altogether. Only a few industrial leaders acquire the hydrogen-added mixture technology, also known as hydrogenation.
