TRIFLUOROMETHANESULFONAMIDE Nrog CAS 421-85-2
Trifluoromethanesulfonamide yog ib qho organic intermediate, uas tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm trifluoromethanesulfonyl chloride thiab ammonia roj. Trifluoromethanesulfonyl tuaj yeem siv los npaj LiTFSI. LiTFSI yog ib qho khoom siv electrolyte zoo heev rau cov roj teeb lithium. Vim yog cov qauv tshuaj tshwj xeeb ntawm anion ib feem (CF3SO2) 2N-, LiTFSI muaj kev ruaj ntseg electrochemical siab thiab kev ua hluav taws xob conductivity; Piv nrog LiClO4 thiab LiPF6, LiTFSI ua electrolyte additive tuaj yeem: 1) txhim kho SEI zaj duab xis ntawm cov electrodes zoo thiab tsis zoo; 2) ruaj khov qhov interface ntawm cov electrodes zoo thiab tsis zoo; 3) inhibit tsim roj; 4) txhim kho kev ua haujlwm ntawm lub voj voog; 5) txhim kho kev ruaj ntseg kub siab; 6) Txhim kho kev ua haujlwm cia khoom thiab lwm yam zoo.

Ntxiv 172g ntawm 98% CF3SO2Cl (1mol) thiab 500mL ntawm anhydrous acetonitrile tom qab kho dej hauv lub reactor kaw nrog lub ntsuas kub, lub stirrer, thiab nitrogen thiab oxygen tshem tawm. Cov roj ammonia lossis cov nqi sib xws ntawm cov ammonium carbonate qhuav maj mam nce mus rau chav tsev kub hauv qab kev nplawm, thiab qhov kev cuam tshuam raug xaus tom qab 3 teev ntawm kev cuam tshuam. Cov khoom lag luam ammonium chloride hauv cov tshuaj tiv thaiv tau raug tshem tawm los ntawm kev lim dej, cov kuab tshuaj hauv cov lim dej tau distilled tawm hauv qab qhov siab txo qis, thiab ziab hauv qab qhov siab txo qis ntawm 50 ° C kom tau txais cov wafer dawb crude trifluoromethanesulfonamide nrog cov txiaj ntsig tsis tsawg dua 96%.
