1,3-Dimethyl-2-imidazolidinone Chemical Properties,Usage,Production

Description

DMI, a high purity aprotic solvent, is composed of nitrogen containing five membered ring compound and widely recognized as an epoch making solvent. It is a colorless, transparent, high polar solvent with high thermal and chemical stability and non-corrosiveness. The material has a high boiling point of 222° C, a high flash point of 120° C (open method) / 95° C (close method), and a low melting point of 7.5° C.

Chemical Properties

Almost colorless, clear liquid

Uses

1,3-Dimethyl-2-imidazolidinone is used as a high-boiling polar aprotic solvent. It is used as a substitute solvent for toxic hexamethylphosphoramide. It finds application in detergents, dyestuffs, electronic materials and in the manufacture of polymers. It is involved in the preparation of 1,2-bis(trimethylsilyl)benzene. Further, it is utilized as a solvent during alfa-regioselective prenylation of imines. In addition to this, it constitutes the mobile phase during size-exclusion chromatographic analysis of cellulose.

Uses

DMI can be used in a variety of applications including detergents, dyestuffs, electronic materials and in the manufacture of polymers. Its versatility can be attributed to it. Of particular note are its excellent solubility for inorganic and organic compounds and high dielectric constant and solvation effect.

Uses

1,3-Dimethyl-2-imidazolidinone may be used:

  • As substitute solvent for hexamethylphosphoric triamide (HMPA) in the synthesis of 1,2-bis(trimethylsilyl)benzene.
  • As solvent during the α-regioselective prenylation of imine.
  • As component of mobile phase for the size-exclusion chromatographic analysis of cellulose.

Definition

ChEBI: 1,3-Dimethyl-2-imidazolidinon is an imidazolidinone.

General Description

1,3-Dimethyl-2-imidazolidinone (DMI) is an imidazolidine derivative. It is reported to act as a promoter by minimizing the formation of dialkylation byproducts and accelerating the rate of monoalkylation of γ-butyrolactone. Conversion of CO2 to form lower alcohols by homogeneous catalytic hydrogenation using DMI as solvent has been investigated.

Flammability and Explosibility

Non flammable
