Basic use

1. Dimethyl sulfoxide is widely used as a solvent and reaction reagent, especially as a processing solvent and spinning solvent in the polymerization of acrylonitrile, as a polyurethane synthesis and spinning solvent, as a polyamide, polyimide and polysulfone resin Synthetic solvents, as well as aromatics, butadiene extraction solvents and synthetic chlorofluoroaniline solvents.

2. Used as a solvent for acetylene, aromatic hydrocarbon, sulfur dioxide and other gases and as a solvent for spinning acrylic fiber. It is an extremely important aprotic polar solvent that is soluble in water and organic solvents. It has strong permeability to the skin and helps the drug to penetrate into the human body. It can also be used as an additive for pesticides. It is also a very important chemical reagent.

3. Used for aromatic extraction, resin and dye reaction medium, acrylic fiber polymerization, spinning solvent, etc.

4. It can be used as organic solvent, reaction medium and organic synthesis intermediate. Very versatile.

5. Used as an analytical reagent and a stationary liquid for gas chromatography, and also as a solvent for ultraviolet spectrum analysis.
