E noiʻi i ke kaʻina hana synthesis o bis(fluorosulfonyl)amide

I loko o kahi kaiapuni koʻikoʻi, lilo ka nānā ʻana i nā spectroscopy pūnaewele i ʻano noiʻi kūpono.

Hiki ke hoʻohana ʻia ka Lithium bis(fluorosulfonyl)amide (LiFSI) i mea hoʻohui no nā electrolytes pākaukau lithium-ion, me nā pono e like me ke kiʻekiʻe o ka ikehu kiʻekiʻe, ke kūpaʻa wela, a me ka palekana.Ke ʻike nui ʻia nei ka makemake o ka wā e hiki mai ana, e lilo ia i wahi wela i ka noiʻi ʻenehana ʻenehana hou.

ʻO ke kaʻina hana synthesis o LiFSI e pili ana i ka fluoridation.Hoʻopili ʻo Dichlorosulfonyl amide me HF, kahi i pani ʻia ai ka Cl i loko o ka hale molekala e F, e hana ana i ka bis(fluorosulfonyl)amide.I ka wā o ke kaʻina hana, hana ʻia nā huahana waena i hoʻololi ʻole ʻia.He koʻikoʻi nā kūlana hoʻonā: HF ʻino loa a ʻona loa;hiki mai nā hopena ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi, e hoʻoweliweli i ke kaʻina hana.

I kēia manawa, nui nā noiʻi e pili ana i kēia pane e pili ana i ka ʻimi ʻana i nā kūlana hopena maikaʻi loa e hoʻonui ai i ka hua huahana.ʻO ka ʻenehana ʻike pahemo wale nō i loaʻa no nā ʻāpana āpau ʻo ka F nuclear magnetic resonance (NMR) spectrum.ʻO ke kaʻina hana ʻike he paʻakikī loa, hoʻopau manawa, a weliweli.I loko o ka hopena hoʻololi, e mau ana no kekahi mau hola, pono e hoʻokuʻu ʻia ke kaomi a lawe ʻia nā laʻana i kēlā me kēia 10-30 mau minuke.A laila hoʻāʻo ʻia kēia mau laʻana me F NMR e hoʻoholo i ka ʻike o nā huahana waena a me nā mea maka.He lōʻihi ka pōʻaiapili hoʻomohala, paʻakikī ka laʻana, a pili pū ke kaʻina hana laʻana i ka pane ʻana, ʻaʻole i hōʻike ʻia ka ʻikepili hōʻike.

Eia naʻe, hiki i ka ʻenehana nānā pūnaewele ke hoʻoponopono pono i nā palena o ka nānā ʻana ma waho.Ma ke kaʻina hana, hiki ke hoʻohana ʻia ka spectroscopy pūnaewele no ka nānā ʻana i ka manawa maoli i loko o ka wahi o nā reactants, nā huahana waena, a me nā huahana.Hiki pololei ka ʻimi kaiapuni ma lalo o ka ʻili wai i loko o ka ipu hao.Hiki i ka probe ke pale i ka corrosion mai nā mea e like me HF, hydrochloric acid, a me chlorosulfonic acid, a hiki ke ʻae a hiki i 200 ° C wela a me 15 MPa kaomi.Hōʻike ka pakuhi hema i ka nānā ʻana ma ka pūnaewele o nā reactants a me nā huahana waena ma lalo o ʻehiku kaʻina hana.Ma lalo o ka palena 7, ʻoi aku ka wikiwiki o ka hoʻopau ʻana i nā mea maka, a ua hoʻopau ʻia ka hopena i ka mua, e lilo ia i mea maikaʻi loa.
