Introduction to dimethyl sulfoxide

Dimethyl sulfoxide introduction and characteristics
Dimethyl sulfoxide (DMSO) is a kind of sulfur content organic matter, chemical formula C2H6OS, normal temperature state is colorless odorless transparent liquid, is a kind of water-absorbing flammable liquid. With high positive and negative electrodes, ether, good heat resistance, non-antiproton, and water miscible characteristics, can dissolve in alcohol, propanol, benzene and B * and other most organic compounds, known as “wan organic solvent.” In acid storage, heating can also produce a little hydroxyl carbon alcohol, indoor formaldehyde, dimethyl sulfur, mesylate and other chemical substances. It is dissolved at high temperature and can produce a violent reaction in the case of chlorine, igniting a light blue flame in the air. It can be used as organic solution, reflection substance and organic chemical intermediate. It can also be used as an organic solvent for dyeing artificial fibers, removing dyes, coloring media and adsorbent for recycling acetylene gas and sulfur dioxide.

Dimethyl sulfoxide actual main use
Dimethyl sulfoxide (DMSO) is an important non-antiprotic polar solvent that is soluble in both water and organic solutions. Generally used as an organic solvent and a reflection experimental reagent, it has a high level of selection and extraction. Dimethyl sulfoxide itself has anti-inflammatory and analgesic, beneficial to urination, calming and other effects, and can also be used as raw materials and media for some drugs in the chemical industry. It has the reputation of “cure-all” and is often added to medicines as an active component of pain relief drugs.
1, for aromatic extraction, epoxy resin and dye reaction substances, polyamide convergence, scraping solution.
2, can be used as organic solution, reflection substance and chemical synthesis of chemical intermediates. The main uses are very wide. This product has a high selective extraction level, as acrylic emulsion and polysulfone resin convergence and condensation reaction organic solvent, polythiophene and formic acid fiber convergence scraping organic solvent, ethane and p-xylene separate extraction organic solvent, used for p-xylene, butadiene extraction, nylon spinning, plastic organic solvent and organic chemical dye, pharmaceutical industry reaction material. At the biomedical level, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and is very permeable to the skin, so it can dissolve some drugs, so that such drugs can penetrate into the body to achieve the purpose of healing. The use of dimethyl sulfoxide such media characteristics, can also be used as a fertilizer additive. Adding a little dimethyl sulfoxide to some fertilizers is conducive to the infiltration of fertilizers into green plants to enhance the drug power. Dimethyl sulfoxide can also be used as an organic solvent, dye removal, coloring medium for artificial fibers, and can also be used as an adsorbent for recycling acetylene gas and sulfur dioxide, artificial fiber modified materials, antifreeze and its capacitor material, brake fluid, non-ferrous metal acquisition agent, etc.
3, as an analytical reagent and meteorological chromatograph fixed liquid, but also as an organic solvent for ultraviolet spectral analysis.
4, dialysis vulcanization accelerator. Dimethyl sulfoxide is one of the fast transdermal penetration vulcanization accelerators, and its permeability promoting properties are likely to be more related than that of organic solvents. Dimethyl sulfoxide can hydrolyze the protein in keratinocytes. It can destroy the orderly arrangement of lipids between thin cells of stratum corneum. It can remove cuticle lipids and proteins and improve the diffusion effect of drugs, but when using dimethyl sulfoxide with a higher concentration, the skin will cause red rashes, small blisters and reversible damage, which has been banned abroad. The common concentration is 30%-50%.
5. Antifreeze. The zero degree of pure dimethyl sulfoxide is 18.45℃, the water content of 40% dimethyl sulfoxide is not ice-60 ℃, and dimethyl sulfoxide is exothermic when mixed with water and snow. Therefore, it is convenient to make antifreeze, brake fluid and hydraulic fluid components. Ethylene glycol antifreeze is not suitable for ultra-low temperatures beyond -40 ° C, even lower than the boiling point of dimethyl sulfoxide, harmful, easy to produce gas blocking. Dmso automotive antifreeze is used in vehicles and armored fighting vehicles in the cold north, and can be filled with snow instead of water at any time. Dimethyl sulfoxide is also used in deicing agents, architectural coatings, a variety of natural latex antifreeze, automotive gasoline, aviation kerosene antifreeze, spinal cord, blood night, human organs cold storage antifreeze.
