WebbSeparation from Aqueous Solution A typical feed to a recovery operation is relatively weak in DMSO – 10 to 20 weight percent. Therefore, there are usually three general steps in the operation: Concentration of the dilute DMSO-water solution to 40-70% DMSO. WebbPolymer membranes, including those from PES, are typically fabricated using phase inversion processes such as non-solvent induced phase separation (NIPS), 10 vapor induced phase separation (VIPS) 11 and thermal induced phase separation (TIPS). 12 Amongst these techniques, NIPS is widely used as it is easy to achieve with minimal …

WebbThe products are easily recovered by venting the CO 2, in contrast to processes carried out in organic solvents, thus avoiding the use of extensive separation processes. Recently, the formation of NMP polymer networks by copolymerization of styrene (Sty) and divinylbenzene (DVB) using 2,2,6,6-Tetramethylpiperidinyl-1-oxyl (TEMPO) and … N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide. It is used in the petrochemical, polymer and battery industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials (includ…
