개요
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.
화학적 성질
Almost colorless, clear liquid
용도
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.
일반 설명
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.
