TRIFLUOROMETHANESULFONAMIDE ke eng Ka CAS 421-85-2?

Trifluoromethanesulfonamide ke organic intermediate, e ka lokisoang ke karabelo ea trifluoromethanesulfonyl chloride le khase ea ammonia. Trifluoromethanesulfonyl e ka sebelisoa ho lokisa LiTFSI. LiTFSI ke tlatsetso e ntle ea organic electrolyte bakeng sa libeteri tsa lithium. Ka lebaka la sebopeho se khethehileng sa lik'hemik'hale sa karolo ea anion (CF3SO2) 2N-, LiTFSI e na le botsitso bo phahameng ba electrochemical le conductivity ea motlakase; Ha ho bapisoa le LiClO4 le LiPF6, LiTFSI e le tlatsetso ea electrolyte e ka: 1) ho ntlafatsa filimi ea SEI ea li-electrode tse ntle le tse mpe; 2) tsitsisa sebopeho sa li-electrode tse ntle le tse mpe; 3) thibela tlhahiso ea khase; 4) ho ntlafatsa ts'ebetso ea potoloho; 5) ntlafatsa botsitso ba mocheso o phahameng; 6) Ntlafatsa ts'ebetso ea polokelo le melemo e meng.

Eketsa 172g ea 98% CF3SO2Cl (1mol) le 500mL ea anhydrous acetonitrile ka mor'a ho phekoloa ha metsi ka sehatsetsing se koetsoeng ka thermometer, sehlaseli, le ho tlosoa ha nitrogen le oksijene. Khase ea ammonia kapa palo e lekanang ea ammonium carbonate e ommeng e nyolleloa butle-butle ho mocheso oa kamore tlas'a ho sisinyeha, 'me karabelo e felisoa ka mor'a lihora tse 3 tsa karabelo. The by-product ammonium chloride tharollong ea karabelo e ile ea tlosoa ka ho tlhotla, solvent e filtrate e ile ea hlakoloa ka tlasa khatello e fokotsehileng, 'me ea omisoa tlas'a khatello e fokotsehileng ka 50 ° C ho fumana trifluoromethanesulfonamide e tšoeu ea wafer crude e nang le lihlahisoa tse seng ka tlase ho. 96%.
