Dissolved organic phosphorus concentrations in the surface ocean
The upwelling-driven elevated DOP production in regions with low PO 4 3 stress allows DOP to accumulate to relatively high concentrations in the eastern Pacific Ocean, as observed in the GO
Reactive Extraction Strategy for Synthesizing Dioctyl Phthalate
As a result, DOP with high purity of 99.01 wt% can be acquired from the bottom of T1, after purifying the crude product in the ester phase of D3. Table 3 . The mass fraction of {MEPA (1) + 2-EH (2) + DOP (3) + H 2 O (4) + DES (5)} in both phases in decanters D1, D2, and D3 predicted by COSMO-RS, and the distribution coefficitents of DES towards the solutes ( β i = w i D E S / w i E s t e r ).
Catalytic Ring Hydrogenation of Phthalate Plasticizers
From Table 5.2, under the conditions of 100 mL Parr autoclave, 130 °C, 800 r/min, 3.0 MPa hydrogen pressure, 40 mL water, and 20 mL DOP, the CDOP and SDEHCH increased with the amount of catalyst used. When the catalyst loading was 0.25% of the DOP mass, the CDOP, SDEHCH, and YDEHCH were 99.43%, 95.60%, and 95.45%, respectively.
Distribution of dissolved organic nutrients and their effect on export
[45] In comparison with the previous coarse-resolution model study, the eddy-permitting results have lower concentrations in DON and DOP over the North Atlantic subtropical gyre, reflecting how lower inorganic nutrient concentrations lead to less DON and DOP production. In the high-resolution case, the DON and DOP patterns have a finer-scale
DOP Plant - Cey Kimya
For production of 1 ton DOP, you need 380 Kg PA + 667 Kg 2EH ------ 1000 Kg DOP + 46 Kg H 2 O But this is teoritical formula. Practically, in reality 380 Kg PA + 667 Kg 2EH ------ 1000 Kg (DOP + DOP mud + loss + wastage) + 46 H 2 O 1000 Kg is NOT only DOP, this amount is total of DOP, DOP mud, loss, wastage
- How patented plasticizer technology is used in DOP production?

- How does DOP synthesis work?
- The schematic diagram of experimental setup for DOP synthesis. After the completion of reaction, the mixtures are settled for 6 h to obtain two phases, and product DOP enriches in the ester phase (upper phase) while DES and water stay in the DES phase (lower phase).
