Oxoviflex (DOTP, DEHT) - Oxoplast
Plasticizers. Oxoviflex (DOTP, DEHT) 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
DOTP Plant - Cey Kimya
With our patented plasticizer technology, we build the most qualified and economic DOTP (Di Octyl Tere Phthalate) production plants. Through the advantages of our technology we have built 11 turn-key DOTP plants in such a short time. The sum of the capacities of plans we built have reached to 200.000 tons/year. PATENTED DOTP PRODUCTION PROCESS
DIOCTYLTEREPHTHALATE (DOTP)
The global Dioctyl Terephthalate (DOTP) market size was USD 1871.1 Mn in 2025 and is expected to reach USD 2339.3 Mn by 2025 growing at a CAGR of 3.8%* The automotive sector held the majority of the DOTP market share in 2025 and is expected to dominate the global market during the period 2025-2025.
Esterification vs. transesterification – comparison of DEHT (DOTP
Two primary methods for the production of di-esters used as plasticizers are the following: esterification (employed by Grupa Azoty ZAK S.A. for production of Oxoviflex (DEHT, DOTP) ) and transesterification (employed by some other manufacturers). The composition and properties of plasticizers may dier based on the production technology.
WO2014185872A1 - Dotp (di-octly terephthalate)production method
A method of production DOTP (Di-Octyl Terephthalate) according to claim 3, characterized in that in production, the use of excess alcohol is 80% to 10%. A method of producing DOTP (Di-Octyl Terephthalate) according to one of the preceding claims, characterized in that the reactor (10) has a structure having a simple stirrer and a heater which is controlled by a temperature control element.
- How hard is DOTP production?
- But, DOTP production is very hard, it requires high technology. Many DOP producers especially in Asia, are trying to produce DOTP with their old DOP technology. But if you produce DOTP with an old DOP technology, the costs will be very high and quality will be low so there will be no chance of competing.
- Why do some countries keep producing DOP instead of DOTP?
- Many DOP producers especially in Asia, are trying to produce DOTP with their old DOP technology. But if you produce DOTP with an old DOP technology, the costs will be very high and quality will be low so there will be no chance of competing. For this reason, these countries keep producing DOP instead of DOTP.
- How many turn-key DOTP plants have we built?
- Through the advantages of our technology, we have built more than 30 turn-key DOTP plants in such a short time. The sum of the capacities of plans we built has reached to 500.000 tons/year. PATENTED DOTP PRODUCTION PROCESS
- Which plasticizers can be produced at the DOTP facility?
- At the DOTP facility, you can produce all plasticizers such as DOP, DOA, DINP, TOTM. 5- Waste from 1 ton DOTP Production 92 kilograms of water will come out of the reaction. 70 kilograms of water will be used to wash a ton of DOTP. 6- If selling price of DOTP and DOP are same why many companies produce DOP not DOTP in asia and developing countries?
- Is there solid waste from DOTP production?
- Washing water includes less than totally %1 soap, 2EH and DOTP. There is not any solid waste from DOTP production. Only on the surface of the filter press there is around 1-2 mm DOTP mug. DOTP Production Flow Diagram DOTP Production We are building DOTP facilities all over the world. Why everyone chooses our technology?
- How does a DOTP reaction work?
- Reaction takes place in unpressurized, open to atmosphere platform. Nitrogen gas is nonutilizable in the reaction. The excess alcohol never turns to yellowish, even when it use a hundred times. There is no alcohol lost or waste in production. Manufactured DOTP colour is always 10 hazen. Turn-Key DOTP plant
