TRIFLUOROMETHANESULFONAMIDE Hamwe na CAS 421-85-2
Trifluoromethanesulfonamide ni organique intermedique, ishobora gutegurwa nigisubizo cya trifluoromethanesulfonyl chloride na gaze ya amoniya.Trifluoromethanesulfonyl irashobora gukoreshwa mugutegura LiTFSI.LiTFSI ninyongera ya electrolyte kama nziza ya bateri ya lithium.Kubera imiterere yihariye yimiti yibice bya anion (CF3SO2) 2N-, LiTFSI ifite amashanyarazi menshi kandi yumuriro w'amashanyarazi;Ugereranije na LiClO4 na LiPF6, LiTFSI nk'inyongera ya electrolyte irashobora: 1) kunoza filime ya SEI ya electrode nziza kandi mbi;2) gushimangira intera ya electrode nziza kandi mbi;3) kubuza kubyara gaze;4) kunoza imikorere yizunguruka;5) kuzamura ubushyuhe bwo hejuru;6) Kunoza imikorere yububiko nibindi byiza.

Ongeramo 172g ya 98% CF3SO2Cl (1mol) na 500mL ya anhydrous acetonitrile nyuma yo gutunganya amazi mumashanyarazi afunze hamwe na termometero, stirrer, hamwe no gukuramo azote na ogisijeni.Gazi ya amoniya cyangwa urugero rwa karubone yumye ya ammonium yumye izamuka buhoro buhoro kugeza ubushyuhe bwibyumba bikurura, kandi reaction irangira nyuma yamasaha 3 yo kwitwara.Ibicuruzwa biva mu bwoko bwa ammonium chloride mu gisubizo cya reaction byakuweho no kuyungurura, ibishishwa muri filtrate byarasibanganywe n’umuvuduko ukabije, hanyuma byumishwa n’umuvuduko wagabanutse kuri 50 ° C kugira ngo ubone trifluoromethanesulfonamide yera ya wafer yera kandi itanga umusaruro utari munsi ya 96%.
