Dimethyl sulfoxide (DMSO) is a kind of sulfur-containing organic compound. It is a colorless and odorless transparent liquid at room temperature, and it is a kind of hygroscopic flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, non proton, and miscible with water. It can dissolve in most organic matters such as ethanol, propanol, benzene and chloroform. Heating in the presence of acid will produce a small amount of methyl mercaptan, formaldehyde, dimethyl sulfur, methanesulfonic acid and other compounds. It can decompose at high temperature, react violently when encountering chlorine, and emit light blue flame when burning in the air. It can be used as organic solvent, reaction medium and organic synthesis intermediate. It can also be used as dyeing solvent, dye remover, dyeing carrier of synthetic fiber, and absorbent for recovering acetylene and sulfur dioxide.
It can be used as organic solvent, reaction medium and organic synthesis intermediate. It has a wide range of applications. This product has very high selective extraction ability. It is used as the polymerization and condensation solvent of acrylic resin and polysulfone tree ester, the polymerization and spinning solvent of Polyacrylonitrile and acetate fiber, the extraction solvent of alkane and aromatics separation, the reaction medium of aromatics, butadiene extraction, acrylic fiber spinning, plastic solvent, organic synthetic dye, pharmaceutical and other industries. DMSO has strong penetration to the skin. Therefore, it can dissolve some drugs and make them penetrate into the human body .Using this carrier property of DMSO, it can also be used as pesticide additive. DMSO can also be used as dyeing solvent, dye remover and dyeing carrier of synthetic fiber, as well as absorbent for recovering acetylene and sulfur dioxide, synthetic fiber modifier, antifreeze, capacitor medium, brake oil, rare meteral extractant, etc.
