Introduction：Colorless viscous liquid. It has hygroscopicity. It can be freely miscible with water, ethanol, acetone, acetaldehyde, pyridine, ethyl acetate, dibutyl phthalate, dioxane and aromatic compounds, but insoluble in aliphatic hydrocarbons other than acetylene.
Dimethyl sulfoxide is widely used as solvent and reaction reagent, especially as processing solvent and drawing solvent in acrylonitrile polymerization reaction, as polyurethane synthesis and drawing solvent, as synthetic solvent of polyamide, polyimide and polysulfone resin, as well as aromatic hydrocarbon, butadiene extraction solvent and synthetic solvent of chlorofluoroaniline.
DMSO is dimethyl sulfoxide, which is widely used. It can be used as solvent for acetylene, aromatics, sulfur dioxide and other gases as well as spinning solvent for acrylic fiber. It is an important nonprotonic polar solvent which is soluble in both water and organic solvents. It has very strong permeability to the skin and helps the drug to penetrate into the human body. It can also be used as additive of pesticide. It is also a very important chemical reagent.
DMSO is also a kind of osmotic protective agent, which can reduce the freezing point of cells, reduce the formation of ice crystals, reduce the damage of free radicals to cells, and change the permeability of biofilm to electrolytes, drugs, poisons and metabolites.
Basic use：At the same time, the transition metal halides such as chromium chloride and manganese chloride have certain solubility with halides such as potassium chloride and sodium chloride in DMSO, so they can be used in organic mechatronics.
Industrial use：Dimethyl sulfoxide (DMSO) is an important nonprotonic polar solvent which is soluble in both water and organic solvents. It is widely used as solvent and reaction reagent with high selective extraction ability. Dimethyl sulfoxide (DMSO) has anti-inflammatory, analgesic, diuretic and sedative effects. It can be directly used as the raw material and carrier of some drugs in the pharmaceutical industry. Known as "panacea", it is often added to drugs as an active component of analgesic drugs.
