N,N-dimethylformamide

Product name N,N-dimethylformamide
Synonyms DMF
GOST no data
CAS 68-12-2

Dimethylformamide is a clear odorless hygroscopic liquid, miscible with water and majority of organic solvents excluding aliphatic hydrocarbons.

Production.

  • Dimethyl formamide is produced with catalyzed reaction of dimethyl amine and carbon monoxide at low pressure and temperature:

    HCOOH + (CH3)2NH --> HCOOH*HN(CH3)2 --> HC(O)N(CH3)2

  • by aminolysis of methylformate with dimethylamine at 80-120°C and 0.1-0.4 mP.
  • Dimethylamine carbonylation in methanol at 100-150°C and 2.5-20 mP in presence of CH3ONa or metal carbonyls results in N,N-dimethylformamide with 95% yield;

    Uses.

  • Dimethylformamide is used as a solvent with low evaporation rate;
  • Dimethylformamide is used in the production of acrylic fibers and polyurethane plastics;
  • in the pharmaceutical industry;
  • in the development and production of pesticides, and in the manufacture of adhesives, synthetic leathers, fibers, films, and surface coatings;
  • It frequently occurs as a component of paint strippers.

  • Manufacturer(s) JSC AZOT
