TRIFLUOROMETHANESULFONAMIDE With CAS 421-85-2
Trifluoromethanesulfonamide ndeye organic yepakati, inogona kugadzirwa nekuita kwe trifluoromethanesulfonyl chloride uye ammonia gasi.Trifluoromethanesulfonyl inogona kushandiswa kugadzira LiTFSI.LiTFSI yakanakisa organic electrolyte yekuwedzera yelithium mabhatiri.Nekuda kwechimiro chakakosha chemakemikari yeanion chikamu (CF3SO2) 2N-, LiTFSI ine yakakwirira electrochemical kugadzikana uye magetsi conductivity;Kuenzaniswa neLiClO4 uye LiPF6, LiTFSI seye electrolyte additive inogona: 1) inovandudza SEI firimu yemagetsi akanaka uye asina kunaka;2) kudzikamisa chimiro chezvakanaka uye zvisina kunaka electrodes;3) inhibit gasi chizvarwa;4) kunatsiridza kutenderera kwekuita;5) kunatsiridza kugadzikana kwekushisa kwepamusoro;6) Kuvandudza mashandiro ekuchengetedza uye zvimwe zvakanakira.

Wedzera 172g ye98% CF3SO2Cl (1mol) uye 500mL yeanhydrous acetonitrile mushure mekuchenesa mvura mu reactor yakavharwa ine thermometer, stirrer, uye nitrogen neoxygen kubvisa.Iyo ammonia gasi kana iyo inoenderana huwandu hweakaoma ammonium carbonate inosimudzwa zvishoma nezvishoma kusvika mukamuri tembiricha pasi pekumutswa, uye kuita kunopera mushure memaawa matatu ekuita.The by-product ammonium chloride in the reaction solution yakabviswa nekusefa, the solvent in the filtrate was distilled off under lower pressure, uye yakaomeswa pasi pekumanikidzwa kwakaderedzwa pa50 ° C kuti iwane white wafer crude trifluoromethanesulfonamide ine goho risingasviki. 96%.
