Trifluoromethanesulfonamide hamwe na CAS 421-85-2
Trifluoromethanesulfonamide ni igikoresho cy’umwimerere, gishobora gutegurwa binyuze mu gukorana kwa trifluoromethanesulfonyl chloride na gaze ya ammonia. Trifluoromethanesulfonyl ishobora gukoreshwa mu gutegura LiTFSI. LiTFSI ni igikoresho cyiza cyane cy’amashanyarazi kuri bateri za lithium. Kubera imiterere yihariye ya anion part (CF3SO2) 2N-, LiTFSI ifite ubushobozi bwo guhagarara neza mu byuma bikoresha amashanyarazi no kuyobora amashanyarazi; Ugereranyije na LiClO4 na LiPF6, LiTFSI nk'igikoresho cy’amashanyarazi ishobora: 1) kunoza filime ya SEI ya electrodes nziza na mbi; 2) gutuza imiterere ya electrodes nziza na mbi; 3) kubuza imyuka gukora; 4) kunoza imikorere y'uruziga; 5) kunoza ubushyuhe bwinshi; 6) kunoza imikorere yo kubika n'ibindi byiza.

Ongeraho garama 172 za 98% CF3SO2Cl (1mol) na 500mL ya acetonitrile ya anhydrous nyuma yo gusukura amazi mu cyuma gifunze hakoreshejwe thermometer, stirrer, hanyuma uvane azote na ogisijeni. Imyuka ya ammonia cyangwa ingano ijyanye na ammonium carbonate yumye izamuka buhoro buhoro ikagera ku bushyuhe bw'icyumba mugihe cyo kuvanga, kandi ingaruka zirangira nyuma y'amasaha 3 yo kuvanga. Ammonium chloride yavuye mu cyuma cyo kuvanga yakuweho binyuze mu kuyungurura, umuti wo mu cyuma uvanwaho ugabanutse, hanyuma wumisha ugabanutse ku bushyuhe kuri 50°C kugira ngo haboneke trifluoromethanesulfonamide y'umweru ifite umusaruro utari munsi ya 96%.
