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

I-Trifluoromethanesulfonamide iyi-organic Intermediate, engalungiswa ngokusabela kwe-trifluoromethanesulfonyl chloride negesi ye-ammonia. I-Trifluoromethanesulfonyl ingasetshenziswa ukulungisa i-LiTFSI. I-LiTFSI iyisengezo se-organic electrolyte esihle kakhulu samabhethri e-lithium. Ngenxa yesakhiwo samakhemikhali esikhethekile sengxenye ye-anion (CF3SO2) 2N-, i-LiTFSI inokuqina okuphezulu kwe-electrochemical kanye nokuhamba kukagesi; Uma kuqhathaniswa ne-LiClO4 ne-LiPF6, i-LiTFSI njengesengezo se-electrolyte ingenza lokhu: 1) ithuthukise ifilimu ye-SEI yama-electrode amahle futhi angalungile; 2) uzinzise isikhombimsebenzisi sama-electrode amahle futhi angalungile; 3) vimbela ukukhiqizwa kwegesi; 4) ngcono ukusebenza komjikelezo; 5) ngcono izinga lokushisa eliphezulu ukuzinza; 6) Thuthukisa ukusebenza kwesitoreji nezinye izinzuzo.

Isicelo

Engeza u-172g ka-98% we-CF3SO2Cl (1mol) kanye no-500mL we-acetonitrile engena-hydrous ngemva kokwelashwa kwamanzi kureactor evaliwe nge-thermometer, i-stirrer, kanye nokukhishwa kwe-nitrogen nomoya-mpilo. Igesi ye-ammonia noma inani elihambisanayo le-ammonium carbonate eyomile liyakhushulwa kancane kancane libe kuzinga lokushisa elilingana negumbi ngaphansi kokunyakaziswa, futhi ukusabela kuyanqanyulwa ngemva kwamahora angu-3 okusabela. I-by-product ammonium chloride esixazululweni sokusabela yasuswa ngokuhlunga, i-solvent ku-filtrate yachithwa ngaphansi kwengcindezi encishisiwe, futhi yomiswa ngaphansi kwengcindezi encishisiwe ku-50 ° C ukuze kutholwe i-wafer emhlophe engahluziwe i-trifluoromethanesulfonamide enesivuno esingekho ngaphansi 96%.
