Product description

DMSO is used in 1. Manufacture of polymer
As a solvent for polyacrylonitrile, it is widely used.In addition, it is also used as urethane manufacturing solvent, photosensitive polymer synthesis solvent and polymerization equipment cleaning agent.
2. Extraction solvent
It has good solubility for aromatic compounds, unsaturated hydrogen carbides and sulfur compounds. However, the solubility of paraffin is very low, so the BTX extraction process (IFP) was developed.
3. Solvents and raw materials for pesticides
The pesticide which is difficult to dissolve in other solvents is easy to dissolve in DMSO, and through the strong penetration of DMSO, the pesticide will penetrate into the whole tree, increasing the effect of pesticide.
DMSO itself is the raw material of the reaction, which is used in the production of pesticides.
4. Solvents for dyes and pigments
DMSO can be used as a solvent for dyes and pigments to improve their stability. The dyeing amount of organic pigment will be increased with the addition of DMSO.
In addition, in view of low toxicity, more and more products are converted to DMSO.
5. Stripping agent
DMSO can be used as stripping agent. If DMSO is added to the coating stripping agent, the effect can be improved. DMSO is particularly effective in the removal of epoxy coatings.
6. Rust inhibitor
It is used as a solvent for some kind of antirust agent.
In addition, DMSO itself can inhibit the growth of microorganisms.
7. Pharmaceutical synthesis reaction solvent
In addition to cephalosporins, they are widely used as reaction medium and refining solvent for many kinds of pharmaceutical products.
8. Cleaning of precision machinery and electronic components
The low toxicity of DMSO has attracted special attention. Moreover, if such articles are put into DMSO, such as freezing and dissolving again, the cleaning effect will be improved.
9. Impregnation in polymer
When the thermal instability material is added to the polymer, the target material is dissolved in DMSO, and the polymer in the solution is dried after deposition. This method is under discussion.
10. To plant
DMSO is also effective on plants.
It can promote the growth of plants by releasing water containing DMSO.
11. Improvement of polymer properties
DMSO can be added to a polymer to improve its properties.
12. Film processing
It is used in the manufacture of hollow fiber, external limiting filtration membrane, reverse osmosis membrane and ion exchange membrane for artificial kidney.CAS is 67-68-5; Package is 225kg/drum.
