Ubushakashatsi kuri synthesis ya bis (fluorosulfonyl) amide

Mubidukikije byangirika cyane, kugenzura spekitroscopi kumurongo biba uburyo bwiza bwubushakashatsi.

Litiyumu bis (fluorosulfonyl) amide (LiFSI) irashobora gukoreshwa nk'inyongera ya batiri ya lithium-ion ya electrolytite, hamwe nibyiza nko kuba ingufu nyinshi, umutekano muke, n'umutekano.Ibisabwa ejo hazaza biragenda bigaragara cyane, bituma biba ihuriro mubushakashatsi bushya bwinganda zinganda.

Synthesis inzira ya LiFSI ikubiyemo fluoridation.Dichlorosulfonyl amide yitwara hamwe na HF, aho Cl mumiterere ya molekile isimburwa na F, ikabyara bis (fluorosulfonyl) amide.Mugihe cyibikorwa, ibicuruzwa byo hagati bitasimbuwe byuzuye birakorwa.Imiterere yimyitwarire irakomeye: HF irashobora kwangirika cyane kandi ni uburozi bukabije;reaction ibaho munsi yubushyuhe bwinshi nigitutu, bigatuma inzira iba mbi cyane.

Kugeza ubu, ubushakashatsi bwinshi kuri iki gisubizo bwibanze ku gushakisha uburyo bwiza bwo kwitwara kugirango umusaruro wiyongere.Tekinike yonyine yo gutahura iboneka kubice byose ni F ya magnetiki resonance (NMR).Inzira yo gutahura iragoye cyane, itwara igihe, kandi iteje akaga.Mubisubizo byo gusimbuza, bimara amasaha menshi, igitutu kigomba kurekurwa kandi ingero zifatwa buri minota 10-30.Izi ngero noneho zipimwa hamwe na F NMR kugirango hamenyekane ibikubiye mubicuruzwa bigezweho n'ibikoresho fatizo.Inzira yiterambere ni ndende, icyitegererezo kiragoye, kandi uburyo bwo gutoranya nabwo bugira ingaruka kubitekerezo, bigatuma amakuru yikizamini adahagarariwe.

Nyamara, tekinoroji yo gukurikirana kumurongo irashobora gukemura neza imbogamizi zo kugenzura kumurongo.Muburyo bwiza bwo gutezimbere, kumurongo wa spekitroscopi urashobora gukoreshwa mugukurikirana igihe nyacyo-cyerekezo cyibintu bya reaction, ibicuruzwa hagati, nibicuruzwa.Ubushakashatsi bwibiza bugera munsi yubuso bwamazi mumasafuriya.Iperereza rishobora kwihanganira ruswa ikomoka ku bikoresho nka HF, aside hydrochloric, na aside ya chlorosulfonike, kandi irashobora kwihanganira ubushyuhe bugera kuri 200 ° C hamwe n’umuvuduko wa MPa 15.Igishushanyo cyibumoso cyerekana kugenzura kumurongo wa reaction hamwe nibicuruzwa bigereranijwe munsi yibice birindwi.Munsi ya parameter 7, ibikoresho fatizo bikoreshwa byihuse, kandi reaction irangira kare, bigatuma iba reaction nziza.
