Trifluoromethanesulfonamide yokhala ndi CAS 421-85-2
Trifluoromethanesulfonamide ndi chinthu chachilengedwe, chomwe chingakonzedwe ndi momwe trifluoromethanesulfonyl chloride ndi mpweya wa ammonia zimagwirira ntchito. Trifluoromethanesulfonyl ingagwiritsidwe ntchito pokonzekera LiTFSI. LiTFSI ndi chinthu chabwino kwambiri chowonjezera cha organic electrolyte cha mabatire a lithiamu. Chifukwa cha kapangidwe kake ka mankhwala ka gawo la anion (CF3SO2)2N-, LiTFSI ili ndi kukhazikika kwamagetsi komanso kuyendetsa magetsi; Poyerekeza ndi LiClO4 ndi LiPF6, LiTFSI monga chowonjezera cha electrolyte ingathe: 1) kukonza filimu ya SEI ya ma electrode abwino ndi oipa; 2) kukhazikitsa mawonekedwe a ma electrode abwino ndi oipa; 3) kuletsa kupanga mpweya; 4) kukonza magwiridwe antchito a cycle; 5) kukonza kukhazikika kwa kutentha kwambiri; 6) Kukonza magwiridwe antchito osungira ndi zabwino zina.

Onjezani 172g ya 98% CF3SO2Cl (1mol) ndi 500mL ya acetonitrile ya anhydrous mutathira madzi mu reactor yotsekedwa ndi thermometer, stirrer, ndi kuchotsa nayitrogeni ndi okosijeni. Mpweya wa ammonia kapena kuchuluka kofanana kwa ammonium carbonate youma kumakwezedwa pang'onopang'ono kutentha kwa chipinda mukasakaniza, ndipo izi zimathetsedwa patatha maola atatu mutasakaniza. Ammonium chloride yomwe imapangidwa mu yankho la reaction inachotsedwa posefa, solvent mu filtrate inasungunuka pansi pa kupanikizika kochepa, ndipo inaumitsidwa pansi pa kupanikizika kochepa pa 50°C kuti mupeze trifluoromethanesulfonamide yoyera yokhala ndi phindu losachepera 96%.
