Zusammenfassung:PROBLEM TO BE SOLVED: To provide disulfonic acid ester derivatives useful as ingredients for producing bis-quaternary ammonium salts efficiently and useful as additives for electrolytes for lithium secondary batteries.SOLUTION: A disulfonic acid ester is represented by the general formula [1'] in the figure. (In the formula, two Reach independently represent a halogen atom or a C1-3 fluoroalkyl group and two m represent integers between 1 and 5.) 【課題】効率的にビス第４級アンモニウム塩を製造するための原料として有用な、また、リチウム二次電池用電解液の添加剤として有用な、ジスルホン酸エステル誘導体を提供すること。【解決手段】下記一般式［１'］で示されるジスルホン酸エステル。（式中、２つのＲ１６は夫々独立して、ハロゲン原子又は炭素数１〜３のフルオロアルキル基を表し、２つのｍは１〜５の整数を表す。）【選択図】図１
