TRIFLUOROMETHANESULFONAMIDE Me CAS 421-85-2
ʻO Trifluoromethanesulfonamide kahi mea hoʻohui kūlohelohe, hiki ke hoʻomākaukau ʻia e ka hopena o ka trifluoromethanesulfonyl chloride a me ke kinoea amonia.Hiki ke hoʻohana ʻia ka Trifluoromethanesulfonyl e hoʻomākaukau i ka LiTFSI.ʻO LiTFSI kahi mea hoʻohui electrolyte organik maikaʻi loa no nā pā lithium.Ma muli o ke ʻano kemika kūikawā o ka ʻāpana anion (CF3SO2) 2N-, loaʻa i ka LiTFSI ke kūpaʻa electrochemical kiʻekiʻe a me ka conductivity uila;Hoʻohālikelike ʻia me LiClO4 a me LiPF6, LiTFSI e like me ka mea hoʻohui electrolyte hiki ke: 1) hoʻomaikaʻi i ke kiʻi SEI o nā electrodes maikaʻi a maikaʻi ʻole;2) hoʻopaʻa i ka pilina o nā electrodes maikaʻi a maikaʻi ʻole;3) kaohi i ka hana kinoea;4) hoʻomaikaʻi i ka hana pōʻaiapuni;5) hoʻomaikaʻi i ke kūpaʻa wela kiʻekiʻe;6) E hoʻomaikaʻi i ka hana mālama a me nā pono ʻē aʻe.

E hoʻohui i 172g o 98% CF3SO2Cl (1mol) a me 500mL o anhydrous acetonitrile ma hope o ka mālama ʻana i ka wai i loko o kahi reactor pani ʻia me kahi thermometer, kahi mea hoʻouluulu, a me ka wehe ʻana o ka nitrogen a me ka oxygen.Hoʻokiʻekiʻe mālie ʻia ke kinoea amonia a i ʻole ka nui like o ka ammonium carbonate maloʻo i ka lumi wela ma lalo o ka hoʻoulu ʻana, a hoʻopau ʻia ka hopena ma hope o 3 mau hola o ka hopena.Ua wehe ʻia ka ammonium chloride ma ka hopena o ka hopena ma ka kānana ʻana, ua hoʻokaʻawale ʻia ka mea hoʻoheheʻe i loko o ka filtrate ma lalo o ke kaomi hoʻemi ʻia, a hoʻomaloʻo ʻia ma lalo o ke kaomi hoʻemi ʻia ma 50 ° C no ka loaʻa ʻana o kahi wafer crude trifluoromethanesulfonamide keʻokeʻo me ka hua ʻaʻole i emi iho. 96% .
