Yintoni i-15-Crown-5 CAS 33100-27-5?

I-15-Crown ether-5 iyilwelo olungenambala, olucacileyo, olune-viscous olufunxa ngokulula ukufuma kwaye luxubene namanzi. Iyanyibilika kwizinyibilikisi ze-organic ezifana ne-ethanol, benzene, i-chloroform, kunye ne-dichloromethane. Inegunya eliqinileyo elikhethiweyo lokuxutywa kwe-ion ze-sodium kwaye liyi-catalyst yesigaba esisebenzayo kunye ne-agent eyinkimbinkimbi.

Isicelo

1. I-catalyst yokudluliselwa kwesigaba
(1) I-organic synthesis ephuculweyo: iphucula ngokubonakalayo ireyithi yokusabela kunye nesivuno kwiimpendulo ezingafaniyo (ezifana neenkqubo zesigaba solwelo). Umzekelo:
Kwi-reaction ye-benzoin condensation, ukongeza i-7% ye-15-crown ether-5 inokunyusa isivuno ukusuka kwi-low kakhulu ukuya kwi-78%.
Kwindlela yokudibanisa iWurtz yokudibanisa i-silane, ukongeza i-2% ye-15-crown ether-5 inokunyusa isivuno ukusuka kwi-38.2% ukuya kwi-78.8%, kwaye inciphise ixesha lokuphendula ngeeyure ze-3.
(2) Iindidi zokuphendula ezisebenzayo: kubandakanywa ukutshintshwa kwe-nucleophilic, i-redox kunye ne-metal organic reactions, ngokukodwa ezifanelekileyo ukuphendula kweetyuwa ezingaxutywanga (ezifana ne-potassium cyanide) kwi-solvents eziphilayo.
2. Ibhetri electrolyte additive
(1) Ukucinezela i-lithium dendrites: Kwi-lithium ibhetri ye-electrolytes, i-ether-5 yesithsaba i-15 inciphisa i-ion concentration kwi-electrode surface ngokudibanisa i-lithium ion (Li⁺), ukukhuthaza ukuchithwa okufanayo. Iimvavanyo zibonisa ukuba ukongeza i-2% kunokwenza i-lithium deposition layer egudileyo kunye nexineneyo, kwaye ubomi bomjikelezo bukwandiswa ukuya kumaxesha e-178 (Li | Li ibhetri ye-symmetric).
(2) Ukuphucula ukuguqulwa kweebhetri ze-lithium-oksijeni: Ukulawula ukwakhiwa kwe-solvation ye-Li⁺, ukukhuthaza i-kinetics yokubola kwe-Li₂O₂, kunye nokuphucula ukuguqulwa kokuphendula.
(3) Ukusetyenziswa kweebhetri ze-sodium-ion: Sebenzisa i-complexation yayo ekhethiweyo ye-Na⁺ yokwandisa ukuhanjiswa kwe-ion sodium.
3. Ukuhlukana kwe-ion yensimbi kunye nokufumanisa
(1) Utsalo olukhethiweyo: Inesakhono esiphakamileyo sokukhetha ukuntsonkotha kwiications ezifana neNa⁺ kunye ne-K⁺, kwaye isetyenziselwa:
Ukucocwa kwamanzi amdaka ngeeyoni zentsimbi enzima (ezifana nemercury kunye neuranium).
Ukufunyanwa kwakhona kwezinto ezinemitha kwinkunkuma yenyukliya.
(2) I-Electrochemical sensors: Njengeemolekyuli zokuqaphela, ifumanisa ngokuchanekileyo i-ion ezithile (ezifana ne-K⁺ kunye ne-Na⁺) egazini okanye indawo engqongileyo enovakalelo oluphezulu.
4. Amayeza kunye nenzululwazi yezixhobo
(1) Abathwali beziyobisi: Sebenzisa i-biocompatibility yayo (ezinye i-derivatives ezifana ne-2-hydroxymethyl-15-crown ether-5) ukufezekisa ukuhanjiswa kweziyobisi okujoliswe kuyo kunye nokukhululwa okulawulwayo.
(2) Ukulungiswa kwe-porous liquids: Njengomgcini we-solvent, edityaniswe ne-polyhedron ephilayo yesinyithi (efana ne-MOP-18) ukwenza ulwelo lweqondo lobushushu begumbi lolwelo lwe-porous lokwahlula okanye ukugcinwa kwegesi.
5. Ezinye izicelo zoshishino
(1) Ukwenziwa kwedayi: Lungiselela indlela yokusabela ukuphucula ukucoceka kwedayi kunye nesivuno8.
(2) I-Catalysis yensimbi exabisekileyo: Njenge-ligand yokuphucula umsebenzi kunye nokuzinza kwezinto ezithintekayo ezifana neplatinum kunye ne-palladium, kunye nokunciphisa inani leentsimbi ezixabisekileyo ezisetyenzisiweyo.
