use

Used for aromatic extraction, resin and dye reaction medium, acrylic fiber polymerization, spinning solvent and other purposes. It can be used as organic solvent, reaction medium and organic synthesis intermediate. Very versatile. This product has a very high selective extraction ability. It is used as a polymerization and condensation solvent for acrylic resin and polysulfone resin, as a polymerization spinning solvent for polyacrylonitrile and cellulose acetate, and as an extraction solvent for the separation of alkane and aromatics. Aromatics, butadiene extraction, acrylic fiber spinning, plastic solvents, organic synthetic dyes, pharmaceuticals and other industries as reaction media.

In medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong penetration into the skin, so it can dissolve certain drugs and make these drugs penetrate into the human body to achieve the purpose of treatment. Using this carrier characteristic of dimethyl sulfoxide, it can also be used as an additive for pesticides.

Adding a small amount of dimethyl sulfoxide to certain pesticides can help the pesticides penetrate into the plants to improve the efficacy. Dimethyl sulfoxide can also be used as a dyeing solvent, de-dyeing agent, and dyeing carrier for synthetic fibers, as well as an absorbent for recovering acetylene and sulfur dioxide, synthetic fiber modifiers, antifreeze, and capacitor media, brake oil, and extraction of rare metals.
