[CN20] N-N DIMETHYLFORMAMIDE (DMF)

0₫

  • Product Name: N-N DIMETHYLFORMAMIDE (DMF)

  • Product Code: CN20

  • Formula: C3H7NO

  • Packaging: 190 kg/phuy

  • Giang Linh Import-Export Trading Investment Co., Ltd. specializes in providing N-N DIMETHYLFORMAMIDE (DMF) solvent nationwide at the best prices in the market.

  • Uses of the Product:

  • 1. SOLVENT FOR THE PLASTICS INDUSTRY

  • Polyacrylonitrile
    Polyacrylonitrile solutions in Dimethylformamide (DMF) have a relatively high concentration and suitable viscosity for fiber spinning. Due to the low boiling point, it can be recovered, purified, and reused. A small amount of impure solvent (DMF and formic acid) significantly affects the viscosity of the spinning solution and impacts the whiteness and strength of the fiber.
    Dimethylformamide (DMF) is widely used in dry spinning.

  • 2. POLYURETHANE PAINT
    Dimethylformamide (DMF) is used as a solvent for PU paints. During the curing process, PU is dissolved in pure DMF.
    If it is a coating paint, the solution will be diluted with appropriate thinners.

  • 3. NYLON PAINT
    It enhances the elasticity of nylon paint.

  • 4. SOLVENT FOR ELECTRICAL INSULATION VARNISH
    Due to Dimethylformamide's (DMF) high boiling point and excellent dissolving capacity, it is very suitable for the production of electrical insulation varnishes with polyamide and PU resins. These varnishes are highly heat-resistant and corrosion-resistant.

  • 5. GAS PURIFICATION
    Since Dimethylformamide (DMF) is a strong solvent for hydrocarbons and specific gases, it is used to remove:

  • Acetylene from ethylene gas vapors.
  • Butadiene, HCL, H2S, and SO2 from CO gas mixtures.

  • 6. EXTRACTION AGENT
    Dimethylformamide (DMF) and DMF-containing solvent mixtures are used to purify extract liquids of aromatic hydrocarbons.
    It is also used to extract organic compounds, natural products, and pure substances from mixtures.

  • 7. SOLVENT FOR ELECTROLYSIS
    Due to the high dielectric constant of pure Dimethylformamide (DMF), it can dissolve many types of salts and maintain a low-viscosity solution over a wide temperature range. This is extremely useful for electrolysis processes.

  • OTHER APPLICATIONS

  • Used in the production of acrylic fibers and plastics.
  • Used to create peptide bonds in pharmaceuticals and in pesticide production.
  • Used in the production of adhesives, coating films such as leather, fibers, and coatings.
  • Used as a reagent in the synthesis of Bouveault aldehydes and in the Vilsmeier Haack reaction—a method for synthesizing other aldehydes.
  • A catalyst in acyl halide synthesis reactions, particularly alkyl chlorides from carboxylic acids and oxalyl or thionyl chloride.
  • DMF can penetrate most plastics and make them swell, so it is used in solid-phase peptide synthesis and paint removers.
  • Used as a solvent to recover olefins like 1,3-butadiene through distillation.
  • An important raw material in the production of solvent dyes (colorants), used throughout the reaction process.
  • Acetylene gas cannot be compressed and stored alone due to its high explosiveness, so acetylene is dissolved in DMF and stored in metal cylinders.
