| Dimethyl Sulfoxide Product name:Dimethyl sulfoxide Other name: DMSO Chemical formula: C2H6OS CAS No：67-68-5 EINECS.No:200-664-3 H ▪ S CODE: 2930300090 Properties: Colourless viscous liquid, melting point 18.45°C, boiling point 189°C; flammable, odourless, with a bitter taste; except for petroleum ether, it can dissolve general organic solvents Application：1.In industry, dimethylsulfoxide is an extremely important non-protonic polar solvent that is soluble in both water and organic solvents. Widely used as a solvent and reaction reagent, it has a high selective extraction capacity. 2.In petroleum processing, DMSO is used as an extraction solvent in aromatic extraction and is soluble in organic sulfides, aromatics and alkynes, and is commonly used in lubricating oil and diesel refining. |
3.In pharmaceutical production, DMSO is used as a reaction solvent in the synthesis of pharmaceutical intermediates.
4.In pesticides and agricultural fertilizers, DMSO is a solvent, penetrating agent and synergist for pesticides and agricultural fertilizers.
5.In paint, DMSO is used as solvent, co-solvent and antifreeze agent, and is used more in water emulsion paint.
6.In organic synthesis, DMSO plays the dual role of reaction solvent and reaction test in chemical reactions, and has accelerating and catalytic effects on certain chemical reactions, improving the yield and reforming the performance of products.
Packing: 220KG plastic drum, which can also be sub-packed or transported by ISO tank according to customer's requirements.
