Dimethyl sulfoxide introduction
Dimethylsulfoxide (DMSO for short) is a sulfur-containing organic compound, English Dimethylsulfoxide, molecular formula (CH3) 2SO, at room temperature is colorless odorless transparent liquid, with hypersonic flammable liquid, both high polarity, high boiling point, aprotic, water mismissibility characteristics, very low toxicity, good thermal stability, It is not mixed with alkanes, and can dissolve in water, ethanol, propanol, ether, benzene and chloroform and other most organic matter, known as “universal solvent”.
Dimethyl sulfoxide is one of the most powerful organic solvents in common use. It can dissolve most organic matter, including carbohydrates, polymers, peptides, and many inorganic salts and gases. It can dissolve solutes equal to 50-60% of its weight (other common solvents can only dissolve 10-20%), so it is important in sample management and high-speed drug screening. Under certain conditions, an explosive reaction occurs when dimethyl sulfoxide comes into contact with an acyl chloride.
Dimethyl sulfoxide is widely used as a solvent and reaction reagent, especially as a processing solvent and drawing solvent in acrylonitrile polymerization, as a polyurethane synthesis and drawing solvent, as a synthetic solvent of polyamide, polyimide and polysulfone resin, and as a solvent for aromatics, butadiene extraction and synthesis of chlorofluoraniline. In addition, in the pharmaceutical industry, dimethyl sulfoxide is also directly used as a raw material and carrier for some drugs. Dimethyl sulfoxide itself has anti-inflammatory analgesic, diuretic, sedative and other effects, and is also known as a “panacea”, often added to drugs as an active component of analgesic drugs. It has a special property that easily penetrates the skin, causing users to feel like oysters.
Dimethyl sulfoxide solution of sodium cyanide can cause cyanide poisoning through skin contact. Dso itself is less toxic. Dimethyl sulfoxide is used as an extractant by most chemical and pharmaceutical enterprises, but due to the high boiling point of DMSO, the operating temperature is too high, which causes the coking of materials, affects the recovery of dimethyl sulfoxide and equipment cleaning, and also increases energy consumption. Therefore, the recovery of DSO has become a bottleneck for its further widespread use as an extractant.
The use of dimethyl sulfoxide
It can be used as organic solvent, reaction medium and intermediate of organic synthesis. Extremely versatile.
This product has high selective extraction ability, used as acrylic resin and polysulfone resin polymerization and condensation solvent, polyacrylonitrile and acetic acid fiber polymerization drawing solvent, alkane and aromatics separation extraction solvent, used in aromatics, butadiene extraction, acrylic fiber spinning, plastic solvent and organic synthetic dyes, pharmaceutical and other industries reaction medium.
In medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong permeability to the skin, so it can dissolve some drugs, so that such drugs can penetrate into the human body to achieve therapeutic purposes.
Using this carrier property of dimethyl sulfoxide, it can also be used as an additive to pesticides. Adding a small amount of dimethyl sulfoxide to some pesticides helps the pesticide penetrate into the plant to improve its efficacy.
Dimethyl sulphoxide can also be used as a dyeing solvent, stain remover and dyeing carrier of synthetic fibers, and can also be used as an absorber for recovering acetylene and sulfur dioxide, synthetic fiber modifier, antifreeze, capacitive media, brake oil, rare metal extractor and so on.
The latest price of dimethyl sulfoxide is 36000 yuan -42000 yuan/ton, the market has fluctuated, please consult the customer service of the site for details.
