APPLICATION
Dimethylformamide is used in a variety of industrial and commercial applications, including:
- Solvent: Dimethylformamide is an excellent solvent for a wide range of organic compounds, including polymers, resins, and dyes. It is particularly useful in the production of polyacrylonitrile fibers, which are used in the production of textiles and carbon fibers.
- Chemical synthesis: Dimethylformamide is commonly used as a reactant or solvent in a variety of chemical reactions, including the production of pharmaceuticals, agrochemicals, and plastics.
- Electrolyte: Dimethylformamide is used as an electrolyte in lithium-ion batteries and supercapacitors.
- Polymer processing: Dimethylformamide is used in the production of films, fibers, and other polymer products. It can also be used as a plasticizer to improve the flexibility and durability of certain materials.
Packaging:
Dimethylformamide is typically packaged and shipped in steel drums or plastic containers, ranging in size from 1 gallon to 55 gallons. Larger bulk shipments may also be available in tanker trucks or railcars. It is important to store dimethylformamide in a cool, dry place away from sources of heat or ignition. Proper safety measures, including proper ventilation and personal protective equipment, should be taken when handling dimethylformamide due to its potential health hazards.
