DOP Plant - Cey Kimya
With our patented plasticizer technology, we build the most qualified and economic DOP (Di Octyl Phthalate) production plants. Through the advantages of our technology we have built 14 turn-key DOP plants in such a short time. The sum of the capacities of plans we built have reached to 350.000 tons/year. PATENTED DOP PRODUCTION PROCESS.

Dioctyl Phthalate (DOP) - Chemical Supplier Distributor Chemceed
DOP is a general-purpose plasticizer and long-time industry standard known for its good stability to heat and ultraviolet light, and broad range of compatibility for use with PVC resins. Dioctyl Phthalate can also be used as dielectric and hydraulic fluids. DOP is also a solvent for many chemicals, such as in glowsticks. Grades Available Technical
- What is dioctyl phthalate (DOP)?
- Dioctyl phthalate (DOP) is used in substantial quantities in industry, primarily as a plasticiser for PVC and other polymers. One route to its production is via the esterification of 2-ethylhexanol (2EH) with phthalic anhydride (PA) using a homogeneous catalyst. The process can be carried out in batch reactors.
- What is a dioctyl phthalate production line?
- The invention provides a dioctyl phthalate production line comprising an esterification system, a dealcoholization system, a neutralization/washing system, a stripping system, a filtering and decolorizing system, and a sewage purification and recovery system. All the systems are modified.
- 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?
- 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.
- 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
- What is a DOTP production method?
- The invention also relates to a DOTP production method, comprising a plurality of steps such as esterification, dealcoholization, neutralization/washing, stripping, filtering and decolorizing, sewage purification and recovery, and the like. All the steps are different from those of prior arts.
