Product Description PRODUCT DESCRIPTION Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in ...
of an organic solvent containing at least one organic aprotic solvent which is sufficiently polar to be able to ionize N 2 O 4 . Aprotic solvents disclosed are DMF, DMA, THF, DMSO, acetonitrile, sulpholan and ethylene carbonate. The solution may contain another polymer, e.g. polyacrylonitrile...
inter alia heating the membrane, preferably in a substantially dry state, and preferably above the Tg of the polymer, under an inert atmosphere; and treatment with a polar aprotic solvent, for example acetone, dimethyacetamide (DMA), dimethylformamide (DMF), tetrahydrofuran (THF) and ...
(VII) to prepare vc-seco-DUBA are, without limitation, organic solvents, preferably aprotic solvents, more preferably polar aprotic solvents. Preferred solvents are ether solvents, amide solvents or mixtures thereof. Particularly preferred solvents are THF, DMA, N,N-dimethylformamide (DMF) or ...
Polar solvents such as water, methanol (MeOH), ethanol (EtOH), and isopropanol (iPrOH) dissolve polar and ionic compounds, while the solubility of non-polar compounds, such as lipids or aromatic compounds, is usually poor in polar solvents. However, the addition of semi-polar solvents, ...
