Kodi TRIFLUOROMETHANESULFONAMIDE Ndi CAS 421-85-2 ndi chiyani?

Trifluoromethanesulfonamide ndi organic wapakatikati, amene akhoza kukonzekera ndi zimene trifluoromethanesulfonyl kolorayidi ndi ammonia mpweya. Trifluoromethanesulfonyl itha kugwiritsidwa ntchito pokonzekera LiTFSI. LiTFSI ndi chowonjezera chabwino kwambiri cha organic electrolyte pamabatire a lithiamu. Chifukwa cha mapangidwe apadera a mankhwala a anion part (CF3SO2) 2N-, LiTFSI ili ndi kukhazikika kwa electrochemical komanso kusinthika kwamagetsi; Poyerekeza ndi LiClO4 ndi LiPF6, LiTFSI monga chowonjezera cha electrolyte chingathe: 1) kukonza filimu ya SEI ya ma electrode abwino ndi oipa; 2) kukhazikika mawonekedwe a maelekitirodi zabwino ndi zoipa; 3) kuletsa m'badwo wa gasi; 4) kusintha magwiridwe antchito; 5) kusintha kutentha kwapamwamba; 6) Sinthani magwiridwe antchito ndi zabwino zina.

Kugwiritsa ntchito

Onjezani 172g ya 98% CF3SO2Cl (1mol) ndi 500mL ya anhydrous acetonitrile mukatha kuthira madzi mu riyakitala yotsekedwa ndi thermometer, chotsitsimutsa, ndi kuchotsa nayitrogeni ndi mpweya. Mpweya wa ammonia kapena kuchuluka kwake kowuma kwa ammonium carbonate kumakwezedwa pang'onopang'ono mpaka kutentha pang'onopang'ono ndikugwedezeka, ndipo zomwezo zimatha pambuyo pa maola atatu. The ndi mankhwala ammonium kolorayidi mu anachita njira anachotsedwa kusefera, zosungunulira mu filtrate anali distilled pa kupsinjika yafupika, ndi zouma pansi kuthamanga yafupika pa 50 ° C kupeza yopyapyala yopyapyala yaiwisi trifluoromethanesulfonamide ndi zokolola zosachepera. 96%.
