DOA Plasticizer | Eastman
Product description. Eastman DOA plasticizer (Bis (2-Ethylhexyl) Adipate) is a light colored, oily liquid generally used as a plasticizer for PVC. It can be used alone or blended with other plasticizers, such as DOP or DOTP. In PVC, Eastman DOA features flexibility at low temperatures, good electrical properties, good resistance to
Metalorganic frameworks as recyclable catalysts
In practical, the classic plasticizer DOTP is generally synthesized by esterification reaction of BDC (1, 4-dicarboxybenzene) and EH (2-ethyl-1-hexanol). Initially, the optimized condition was screened out by the model reaction of the DOTP synthesis catalyzed by MIL-125 MOF.
Oxoviflex (DOTP, DEHT) - Oxoplast
Oxoviflex is the flagship plasticizer of Segment Oxoplast. Oxoviflex is manufactured on a dedicated production plant utilizing strictly controlled technology conditions. Therefore Oxoviflex is min. 99,5 DOTP and does not contain acidic catalyst residues, methanol or phthalates, which has a positive effect on its processing and

It can be used alone or blended with other plasticizers such as DOP or DOTP. In PVC, Eastman DOA Renew 20 plasticizer features flexibility at low temperatures, good electrical properties
Bis(2-ethylhexyl) 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 referred to as octyl.
- What is the difference between DOP and DOTP plasticizer?
- In summary, interest in alternative plasticizers has been increasing, as phthalates are among the harmful chemicals and forbidden in some countries. DOTP plasticizer has been commercialized around 1975 . Due to the structural difference, DOTP is less toxic than DOP. DOTP has been used alternative to phthalate.
- Is DOTP a good alternative to phthalate?
- DOTP has been used alternative to phthalate. Since DOTP is a petroleum-based plasticizer, some researchers are concerned about using it. However, it is a significant advantage that DOTP can be produced from waste PET in addition to direct esterification. Besides, the production cost is generally lower compared to bio-based plasticizers.
- Why is DOTP more stable than other plasticizers?
- Also, the stability of DOTP is greater than that of the other plasticizers due to the compensation ratio. Wang et al. investigated thermal degradation kinetics of PVC with different plasticizers; DOTP, DOP, ATBC, acetyl trioctyl citrate (ATOC), TOTM, and isosorbide ester (ID-37).
- Is DOTP Plasticized PVC a good plasticizer?
- According to the results, DOTP has high compatibility with PVC, and DOTP plasticized PVC shows good migration, mechanical and thermal properties. DOTP is a promising plasticizer due to having good properties, low production cost, and low toxicity. PVC, yaygın olarak tercih edilen termoplastiklerden biridir.
- Can Dioctyl terephthalate be used as a plasticizer for PVC?
- Direct esterification of the obtained TPA and 2-ethyl-1-hexanol at 160 o C for 6 hours yielded dioctyl terephthalate or DOTP. The resulting DOTP was clear and slightly yellowish with a specific gravity of 0.936, a refractive index of 1.472 and an acid value of 0.0044 mg KOH/g. The possibility of using DOTP as a plasticizer for PVC was studied.
- What are the optimal reaction conditions to obtain DOTP?
- Optimum reaction conditions to obtain DOTP were evaluated as 1:3.8 for molar ratio of PET/2-EH and 13.10% for the quality ratio of catalyst/PET. Besides, when reaction temperature and time were 210 °C - 220 °C and 3 h, the productivity value of DOTP enhanced by 96.18% .
