Application
Dimethyl sulfoxide is widely used as solvent of both extraction and reaction as well as
intermediates for the synthesis of textile chemicals and agrochemicals.
Dimethyl sulfoxide is a common solvent for many chemical reactions and is widely used in organic synthesis and industrial applications (polymer chemistry, pharmaceuticals and agricultural chemicals). In organic synthesis, dimethyl sulfoxide can also be used in many oxidation reactions. At the same time, dimethyl sulfoxide is more and more widely used in the production and manufacturing of the microelectronics industry; in medicine, dimethyl sulfoxide is mainly used as topical analgesics, topical drug carriers, anti-inflammatory drugs and antioxidants. Dimethyl sulfoxide is a very important nonprotonic polar solvent that is soluble in both water and organic solvents. Widely used as a solvent and reaction reagent, it has high selective extraction ability. Dimethyl sulfoxide itself has anti-inflammatory, analgesic, diuretic, sedative and other effects, and can be directly used as the raw material and carrier of some drugs in the pharmaceutical industry. It is known as a 'panacea' and is often added as an active component of painkillers to medications.
1. Used as a reaction medium for aromatic hydrocarbon extraction, resins and dyes, as well as a solvent for acrylic fiber polymerization and spinning.
2. It can be used as an organic solvent, reaction medium, and intermediate in organic synthesis. Extremely versatile. This product has a high selective extraction ability, and is used as polymerization and condensation solvent for acrylic resin and polysulfone resin, polymerization and spinning solvent for Polyacrylonitrile and acetic acid fiber, extraction solvent for separation of alkanes and aromatics, extraction of aromatics and butadiene, acrylic fiber spinning, plastic solvent, reaction medium for organic synthetic dyes, pharmaceutical and other industries. In medicine, Dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong penetration to the skin, so it can dissolve some drugs, so that such drugs can penetrate into the human body to achieve therapeutic purposes. This carrier characteristic of Dimethyl sulfoxide can also be used as an additive of pesticides. A small amount of Dimethyl sulfoxide is added to some pesticides to help them penetrate into plants and improve their efficacy. Dimethyl sulfoxide can also be used as the dyeing solvent, dye remover and dyeing carrier of Synthetic fiber, as well as the absorbent for recovering acetylene and sulfur dioxid e, modifier of Synthetic fiber, Antifreeze, capacitor medium, brake oil, rare metal extractant, etc.
3. Used as an analytical reagent and gas chromatography stationary liquid, as well as a solvent for UV spectroscopy analysis.
4. Transdermal enhancer. Dimethyl sulfoxide is one of the earliest transdermal penetration enhancers, and its penetration promoting properties may be related to its solvability. Dimethyl sulfoxide can denature proteins in skin keratinocytes; It can destroy the orderly arrangement of lipids between Stratum corneum cells; It can remove Stratum corneum lipids and lipoproteins, and enhance drug penetration. However, the use of high concentration Dimethyl sulfoxide will cause erythema, blisters and Irreversible process damage to the skin, which has been banned in the United States. The commonly used concentration is *0% **0%.
5. Antifreeze. The freezing point of pure Dimethyl sulfoxide is *8.*5 ºC, and Dimethyl sulfoxide with *0% water is not frozen at **0 ºC, and Dimethyl sulfoxide emits heat when mixed with water and snow. Therefore, it is convenient to make automobile antifreeze, brake oil and Hydraulic fluid components. Ethylene glycol antifreeze is not applicable when the temperature exceeds **0 ºC, and the boiling point is lower than that of Dimethyl sulfoxide. It is toxic and easy to produce gas resistance. Dimethyl sulfoxide antifreeze is used in automobiles and combat vehicles in northern severe cold areas, and can be supplemented with snow instead of water at any time. Dimethyl sulfoxide is also used as deicer, coating, Antifreeze for various emulsions, Antifreeze for gasolin, aviation kerosen, and Antifreeze for bone marrow, blood, and organ cryopreservation.
