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

E hoʻohui i 172g o 98% CF3SO2Cl (1mol) a me 500mL o ka acetonitrile anhydrous ma hope o ka mālama ʻana i ka wai i loko o kahi reactor pani me kahi thermometer, kahi stirrer, a me ka wehe ʻana o ka nitrogen a me ka oxygen. Hoʻokiʻekiʻe mālie ʻia ke kinoea ammonia a i ʻole ka nui like o ka ammonium carbonate maloʻo i ka mahana o ka lumi 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 by-product i loko o ka hopena hopena ma o ka kānana ʻana, ua hoʻoheheʻe ʻia ka mea hoʻoheheʻe i loko o ka filtrate ma lalo o ke kaomi i hoʻemi ʻia, a hoʻomaloʻo ʻia ma lalo o ke kaomi i hoʻemi ʻia ma 50°C e loaʻa ai kahi wafer keʻokeʻo crude trifluoromethanesulfonamide me ka hua ʻaʻole i emi ma mua o 96%.
