PURPOSE:To provide the subject chemically and physically stable, low-viscosity compound high in flash point and dielectric constant, highly soluble for organic compounds, thus useful as a solvent. CONSTITUTION:The objective carbonic ester compound of generic formula [I] can be obtained by ester interchange reaction (as shown below) in the presence of a basic catalyst: R<1>CH2O-CO-OCH2R<1>+R<2>CH2OH R<1>CH2O-CO-OCH2R<2> [I] (R<1> is H, aklyl or halogen-substituted alkyl; R<2> is alpha-halogen-free alkyl or halogen-substituted alkyl). This compound can be used as a solvent in various fields such as the electrolyte solvents for batteries as well as general solvents for organic synthesis; besides, being usable as a reagent for organic synthesis, medicine-pesticide, flame retardant, or detergent. |
