Dimethyl sulfoxide is an important non-proton polar solvent that is both soluble in water and soluble in organic solvents.It is widely used as solvent and reaction reagent, with high selective extraction ability.
1. Used for the reaction medium of aromatic extraction, resin and dye, acrylic polymerization, solvent of drawing silk, etc.
2. Organic solvent, reaction medium and organic synthesis intermediate.
3. Used as analytical reagent and gas chromatographic stationary liquid, and also used as solvent in the analysis of ultraviolet spectra.
4. Antifreeze
