Kafukufuku wa kaphatikizidwe ka bis(fluorosulfonyl)amide

M'malo owononga kwambiri, kuyang'anira zowonera pa intaneti kumakhala njira yabwino yofufuzira.

Lithium bis(fluorosulfonyl)amide (LiFSI) itha kugwiritsidwa ntchito ngati chowonjezera cha ma electrolyte a batri a lithiamu-ion, ndi zabwino zake monga kusachulukira kwamphamvu, kukhazikika kwamafuta, komanso chitetezo.Kufuna kwamtsogolo kukuwonekera kwambiri, ndikupangitsa kuti ikhale malo ambiri ofufuza zamakampani opanga mphamvu zatsopano.

Kaphatikizidwe ka LiFSI kumaphatikizapo fluoridation.Dichlorosulfonyl amide imakumana ndi HF, pomwe Cl mu kapangidwe ka molekyulu imasinthidwa ndi F, kupanga bis(fluorosulfonyl)amide.Panthawiyi, zinthu zapakatikati zomwe sizinalowe m'malo zimapangidwira.Zomwe zimachitika ndizovuta: HF ndi yowononga kwambiri komanso yowopsa kwambiri;zochita zimachitika pansi pa kutentha kwambiri ndi kukakamizidwa, kupanga ndondomeko yoopsa kwambiri.

Pakalipano, kafukufuku wambiri wokhudza izi amayang'ana kwambiri kupeza momwe zinthu zilili bwino kuti ziwonjezeke zokolola.Njira yokhayo yodziwira zinthu popanda intaneti yomwe ilipo pazinthu zonse ndi mawonekedwe a F nuclear magnetic resonance (NMR).Njira yodziwira ndi yovuta kwambiri, imatenga nthawi, komanso yowopsa.Panthawi yonse yosinthira, yomwe imakhala kwa maola angapo, kukakamizidwa kuyenera kumasulidwa ndipo zitsanzo zimatengedwa mphindi 10-30 zilizonse.Zitsanzozi zimayesedwa ndi F NMR kuti mudziwe zomwe zili pakati pa zinthu zapakatikati ndi zopangira.Kuzungulira kwachitukuko kumakhala kwautali, sampuli ndizovuta, ndipo ndondomeko yotsatirira imakhudzanso zomwe zimachitika, zomwe zimapangitsa kuti deta yoyesedwa isakhale yoyimira.

Komabe, ukadaulo wowunikira pa intaneti utha kuthana bwino ndi zoletsa za kuwunika kwapaintaneti.Pakukhathamiritsa, zowonera pa intaneti zitha kugwiritsidwa ntchito kuyang'anira zenizeni zenizeni za in-situ za ma reactants, zinthu zapakatikati, ndi zinthu.The kafukufuku kumiza mwachindunji kufika pansi pa madzi pamwamba mu anachita ketulo.Pulogalamuyi imatha kupirira dzimbiri kuchokera kuzinthu monga HF, hydrochloric acid, ndi chlorosulfonic acid, ndipo imatha kupirira kutentha kwa 200 ° C ndi kuthamanga kwa 15 MPa.Chithunzi chakumanzere chikuwonetsa kuwunika kwapaintaneti kwa ma reactants ndi zinthu zapakatikati pansi pa magawo asanu ndi awiri.Pansi pa gawo 7, zopangira zimadyedwa mwachangu kwambiri, ndipo zomwe zimachitika zimamalizidwa koyambirira, ndikupangitsa kuti ikhale yabwino kwambiri.
