CN102295564A - Continuous production process for DOP (Dioctyl
The continuous production process comprises the following steps of: firstly carrying out esterification reaction of phthalic anhydride and isooctyl alcohol in the presence of a catalyst such as titanate, and then carrying out dealcoholization, neutralization and water washing, steam stripping and drying, adsorption and filtration to obtain the DOP.

CN102952025B - Dioctyl phthalate production line and DOTP
While utilizing the present invention to produce DOTP, within 4-5 hour, can complete esterification, catalyst levels is little, and product cleaning is colourless, and in finished product, alcohol content can be down to 20ppm, and quality improves greatly.Dioctyl phthalate production line of the present invention can be used for producing dioctyl terephthalate, dioctyl phthalate (DOP) and
- 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.
- How patented plasticizer technology is used in DOP production?
- 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
- How much waste is produced from a DOP filter press?
- Necessary Raw Materials to Produce 1 Ton DOP Waste Materials from 1 Ton DOP Production From DOP reaction 46 KG brilliant, light alcohol scented and residue free waste water comes out. There is not any solid waste from DOP production. Only on the surface of the filter press there is around 1-2 mm DOP mug.
- Is there any waste from DOP production?
