Iyini i-TRIFLUOROMETHANESULFONAMIDE ene-CAS 421-85-2?

I-Trifluoromethanesulfonamide iyi-organic intermediate, engalungiswa ngokuphendula kwe-trifluoromethanesulfonyl chloride kanye negesi ye-ammonia. I-Trifluoromethanesulfonyl ingasetshenziswa ukulungiselela i-LiTFSI. I-LiTFSI iyi-organic electrolyte additive enhle kakhulu yamabhethri e-lithium. Ngenxa yesakhiwo samakhemikhali esikhethekile sengxenye ye-anion (CF3SO2)2N-, i-LiTFSI inokuqina okuphezulu kwe-electrochemical kanye nokuqhuba kukagesi; Uma kuqhathaniswa ne-LiClO4 kanye ne-LiPF6, i-LiTFSI njenge-electrolyte additive ingenza okulandelayo: 1) ukuthuthukisa ifilimu ye-SEI yama-electrode amahle nangalungile; 2) ukuzinzisa isikhombimsebenzisi sama-electrode amahle nangalungile; 3) ukuvimbela ukukhiqizwa kwegesi; 4) ukuthuthukisa ukusebenza komjikelezo; 5) ukuthuthukisa ukuzinza kokushisa okuphezulu; 6) Thuthukisa ukusebenza kwesitoreji kanye nezinye izinzuzo.

Isicelo

Engeza u-172g we-98% CF3SO2Cl (1mol) kanye no-500mL we-acetonitrile engamanzi ngemva kokwelashwa ngamanzi ku-reactor evaliwe nge-thermometer, i-stirrer, kanye nokususwa kwe-nitrogen ne-oxygen. Igesi ye-ammonium noma inani elihambisanayo le-ammonium carbonate eyomile liphakanyiswa kancane kancane liye ekushiseni kwegumbi ngaphansi kokuxutshwa, futhi ukusabela kuyaphela ngemva kwamahora ama-3 okusabela. I-ammonium chloride ephumayo esixazululweni sokusabela isusiwe ngokuhluzwa, i-solvent eku-filtrate yancibilikiswa ngaphansi kwengcindezi encishisiwe, futhi yomiswa ngaphansi kwengcindezi encishisiwe ku-50°C ukuze kutholakale i-trifluoromethanesulfonamide emhlophe engacwengekile enesivuno esingaphansi kuka-96%.
