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

I-15-Crown ether-5 iwuketshezi olungenambala, olusobala, ne-viscous olumunca kalula umswakama futhi luxubene namanzi. Incibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-benzene, i-chloroform, ne-dichloromethane. Inamandla okukhetha aqinile e-sodium ion futhi iyisisusa esisebenzayo sokudlulisa isigaba kanye ne-ejenti eyinkimbinkimbi.

Isicelo

1. I-catalyst yokudlulisa isigaba
(1) Ukwenziwa kwe-organic okuthuthukisiwe: kuthuthukisa kakhulu izinga lokusabela kanye nesivuno ekuphenduleni okuhlukahlukene (njengamasistimu esigaba soketshezi oluqinile). Ngokwesibonelo:
Ekuphenduleni kwe-benzoin condensation, ukwengeza u-7% we-ether-5-crown engu-15 kungakhuphula isivuno sisuka kokuphansi kakhulu siye ku-78%.
Endleleni yokuhlanganisa iWurtz yokuhlanganisa i-silane, ukwengeza u-2% we-ether-5 yomqhele kungakhuphula isivuno sisuka ku-38.2% siye ku-78.8%, futhi sifinyeze isikhathi sokuphendula ngamahora ama-3.
(2) Izinhlobo zokusabela ezisebenzayo: kufaka phakathi i-nucleophilic substitution, i-redox kanye ne-metal organic reactions, efaneleka kakhulu ukusabela kosawoti ongancibiliki (njenge-potassium cyanide) kuzinyibilikisi zemvelo.
2. Isengezo se-electrolyte yebhethri
(1) Ukucindezela i-lithium dendrites: Kuma-electrolyte ebhethri ye-lithium, i-ether-5 yomqhele we-15 yehlisa ukugxiliswa kwe-ion endaweni ye-electrode ngokuhlanganisa i-lithium ion (Li⁺), ithuthukise ukubekelwa okufanayo. Ukuhlola kubonisa ukuthi ukungeza u-2% kungakha isendlalelo se-lithium esibushelelezi nesiminyene, futhi impilo yomjikelezo inwetshwa izikhathi ezingu-178 (ibhethri le-Li|Li symmetric).
(2) Thuthukisa ukubuyisela emuva emuva kwamabhethri e-lithium-oksijeni: Lawula ukwakheka kokuxazululwa kwe-Li⁺, thuthukisa i-kinetics yokubola ye-Li₂O₂, futhi uthuthukise ukuhlehla kokusabela.
(3) Ukusetshenziswa kwamabhethri e-sodium-ion: Sebenzisa ukuhlanganiswa kwayo okukhethiwe kwe-Na⁺ ukuze uthuthukise ukusebenza kahle kokudluliselwa kwe-sodium ion.
3. Ukuhlukaniswa kwe-ion yensimbi nokutholwa
(1) Isizinda esikhethiwe: Inekhono eliphezulu lokukhetha eliyinkimbinkimbi lama-cations afana ne-Na⁺ ne-K⁺, futhi isetshenziselwa:
Ukwelashwa kwamanzi angcolile kwama-ion ensimbi esindayo (njenge-mercury ne-uranium).
Ukutholwa kwezinto ezikhipha imisebe kudoti wenuzi.
(2) Izinzwa ze-electrochemical: Njengama-molecule aqaphelayo, ithola ngokunembile ama-ion athile (afana ne-K⁺ ne-Na⁺) egazini noma endaweni enokuzwela okukhulu.
4. Isayensi yezokwelapha nezinto zokwakha
(1) Abathwali bezidakamizwa: Sebenzisa i-biocompatibility yayo (okunye okuphuma kokunye okufana ne-2-hydroxymethyl-15-crown ether-5) ukuze kuzuzwe ukulethwa kwezidakamizwa okuhlosiwe nokukhululwa okulawulwayo.
(2) Ukulungiswa koketshezi oluyizimbotshana: Njengesithathisi esincibilikayo, esihlanganiswe nama-polyhedron enziwe ensimbi (njenge-MOP-18) ukuze kwakheke izinga lokushisa legumbi uketshezi olunamanzi okuhlukanisa igesi noma ukugcinwa.
5. Ezinye izinhlelo zokusebenza zezimboni
(1) Ukwakheka kodayi: Lungiselela indlela yokusabela ukuze uthuthukise ukuhlanzeka kukadayi kanye nesivuno8.
(2) I-Catalysis yensimbi eyigugu: Njenge-ligand yokuthuthukisa umsebenzi nokuzinza kwama-catalysts afana ne-platinum ne-palladium, nokunciphisa inani lezinsimbi eziyigugu ezisetshenziswayo.
