Yield: 94%
Reaction Conditions:
in water at 120; under 3750.38 Torr; for 2 h;
Steps:
1
1 g of 1,2-dichloroethane and 5.5 g of an aqueous 40% methylamine solution were charged in a 20 ml pressure vessel made of SUS316 and 1.9 g of a carbon dioxide gas was absorbed under a pressure of 0.5 MPa, followed by heating at 120° C. for 2 hours. After cooling the pressure vessel, the contents were removed and analyzed by gas chromatography. As a result, N-methyl-2-oxazolidinone was obtained in a 94% yield based on 1,2-dichloroethane. Hydrogen chloride produced, as a by-product, during the reaction was neutralized with excess amine.
