METHOD FOR PRODUCING BIS(omega-HYDRODIFLUOROALKYL) CARBONATE AND NONAQUEOUS ELECTROLYTE

摘要

PPROBLEM TO BE SOLVED: To provide a solvent having flame retardance and having high dissolution ability to electrolytes having high polarity. PSOLUTION: The method for producing a bis(-hydrodifluoroalkyl) carbonate represented by formula 2:(HCFSB2/SB-R-CHSB2/SBO)SB2/SBC=O [R is CSBa/SBHSBb/SBFSBd/SBXSBe/SB; X is a halogen atom other than a fluorine atom; a, b, d and e are each an integer of 0 and b+d+e=2a] comprises reacting an -hydroxyfluoroalkyl alcohol represented by formula 1: HCFSB2/SB-R-CHSB2/SBOH with phosgene in the presence of a tertiary amine.
