  "textContent": "Object To provide a method for producing a bis-quaternary ammonium salt efficiently and a novel synthetic intermediate thereof. Solution The present invention relates to a method for producing a bis-quaternary ammonium salt represented by a general formula [3] which comprises reacting a disulfonic acid ester represented by a general formula [1] (in the formula, definitions of two R 1 's and T are as described in Claim 1) with a tertiary amine represented by a general formula [2] (in the formula, definitions of R 3 to R 5 are as described in Claim 1), and a disulfonic acid ester represented by a general formula [1'] (in the formula, two R 16 's represent independently a halogen atom or a C1-C3 fluoroalkyl group, and two m's represent independently an integer of 1 to 5).",
