TRIFLUOROMETHANESULFONAMIDE Kunye CAS 421-85-2
I-Trifluoromethanesulfonamide yi-organic intermediate, enokuthi ilungiswe ngokusabela kwe-trifluoromethanesulfonyl chloride kunye negesi ye-ammonia.I-Trifluoromethanesulfonyl ingasetyenziselwa ukulungisa i-LiTFSI.I-LiTFSI yeyona nto ibalaseleyo yokongeza i-electrolyte yeebhetri ze-lithium.Ngenxa yokwakheka kweekhemikhali ezikhethekileyo zecandelo le-anion (CF3SO2) 2N-, i-LiTFSI inozinzo oluphezulu lwe-electrochemical kunye nokuhanjiswa kombane;Xa kuthelekiswa ne-LiClO4 kunye ne-LiPF6, i-LiTFSI njenge-additive electrolyte inokuthi: 1) iphucule ifilimu ye-SEI yee-electrodes ezintle kunye nezibi;2) ukuzinzisa i-interface ye-electrodes efanelekileyo kunye nembi;3) inqanda ukuveliswa kwegesi;4) ukuphucula ukusebenza komjikelo;5) ukuphucula ukuzinza kweqondo lokushisa eliphezulu;6) Ukuphucula ukusebenza kokugcinwa kunye nezinye iingenelo.

Yongeza i-172g ye-98% CF3SO2Cl (1mol) kunye ne-500mL ye-acetonitrile ye-anhydrous emva kokunyanga kwamanzi kwi-reactor evaliweyo kunye ne-thermometer, i-stirrer, kunye ne-nitrogen kunye nokususwa kwe-oxygen.Irhasi ye-ammonia okanye isixa esihambelanayo se-ammonium carbonate eyomileyo inyuswa ngokuthe ngcembe kwiqondo lobushushu begumbi phantsi kokuvuselela, kwaye ukusabela kupheliswa emva kweeyure ezi-3 zokusabela.Imveliso ye-ammonium chloride kwisisombululo sokuphendula yasuswa ngokuhluzwa, i-solvent kwi-filtrate yachithwa phantsi koxinzelelo oluncitshisiweyo, kwaye yomiswa phantsi koxinzelelo oluncitshisiweyo kwi-50 ° C ukufumana i-wafer emhlophe ekrwada i-trifluoromethanesulfonamide enesivuno esingekho ngaphantsi kwe 96%.
