PURPOSE: Provided is a fluorinated sulfonamide compound as low combustible solvent for electrochemical battery, which has low volatility and a relatively high ignition point, is physically and chemically stable, can sufficiently be mixed with the other kind of proper solvents, and has good conductive behaviors. CONSTITUTION: The fluorinated sulfonamide compound has a general formula(I): X is H, F, Cl, CnF2n+1, CnF2n-1 or (SO2)kN(CR1R2R3)2, Y is H, F or Cl, Z is H, F or Cl, each R1, R2 and R3 are H and/or an alkyl, a fluoroalkyl or a cycloalkyl, m is 0 to 9, provided that m is not 0 when X is H, n is 1 to 9, k is 0 when m is 0, and k is 1 when m is 1-9. The fluorinated sulfonamide compound is prepared by reacting partially fluorinated or perfluorinated alkylsulfonyl fluoride with dimethylamine in organic solvent. The compound is used in electrochemical battery, as low combustible solvent. |
