Descripiton and applications of Dimethyl sulfoxide DMSO

Dimethyl sulfoxide DMSO is a sulfur-containing organic compound with the molecular formula C2H6OS. It is a colorless and odorless transparent liquid at room temperature. It is a hygroscopic and flammable liquid.

Dimethyl sulfoxide DMSO has the characteristics of high polarity, high boiling point, good thermal stability, aprotic, and miscible with water. It can be dissolved in most organic substances such as ethanol, propanol, benzene and chloroform, and is known as the "universal solvent".

Heating in the presence of acid will produce small amounts of methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid and other compounds.

Dimethyl sulfoxide DMSO has decomposition phenomenon at high temperatures, reacts violently with chlorine, and burns in the air with a light blue flame.

Dimethyl sulfoxide DMSO can be used as organic solvent, reaction medium and organic synthesis intermediate. It can also be used as a dyeing solvent, dye remover, dyeing carrier for synthetic fibers, and an absorbent for recovering acetylene and sulfur dioxide.
