Bacterial community progression during food waste composting
The overall dioctyl terephthalate (DOTP) degradation efficiency during food waste composting was 98%. The thermophilic phases contributed to 76% of the overall degradation efficiency, followed by the maturation phase (22%), then the mesophilic phase (0.7%). The thermophilic phase had the highest specific degradation rate of 0.149 d-1. The
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 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
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]
The Production of “Dioctyl Terephthalate” to replace “Dioctyl
One of the safe and environmentally friendly plasticizers is “Dioctyl Terephthalate” which was recommended by the World Health Organization (WHO), the Food and Drug Administration of the United States of America (FDA) and the European Union (EU). In this paper, I hope, with accurate reviews of the dimension of
- Will Hanwha halt production of phthalate-based plasticizer DOP in 2022?
- Given the growing need for observing the ESG mandate around the world, Hanwha Solutions' Chemical Division is seeking to completely halt its production of phthalate-based plasticizer DOP within 2022.
- 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.
