Kopo

1. Phase transfer catalyst
(1) Ntlafatso ea manyolo e ntlafalitsoeng: e ntlafatsa haholo sekhahla sa karabelo le tlhahiso ho karabelo e fapaneng (joalo ka litsamaiso tsa mokelikeli o tiileng). Ka mohlala:
Karabelong ea benzoin condensation, ho eketsa 7% ea 15-crown ether-5 ho ka eketsa chai ho tloha tlase haholo ho isa ho 78%.
Mokhoa oa ho kopanya oa Wurtz bakeng sa ho kopanya silane, ho eketsa 2% ea 15-crown ether-5 ho ka eketsa chai ho tloha ho 38.2% ho ea ho 78.8%, le ho khutsufatsa nako ea ho arabela ka lihora tse 3.
(2) Mefuta e sebetsang ea karabelo: ho kenyelletsa le nucleophilic substitution, redox le metal organic reactions, haholo-holo tse loketseng karabelo ea matsoai a sa tsitsang (joalo ka potassium cyanide) ka har'a metsoako ea manyolo.
2. Battery electrolyte additive
(1) Ho hatella lithium dendrites: Li-electrolyte tsa betri tsa lithium, 15-crown ether-5 e fokotsa mahloriso a ion sebakeng sa electrode ka ho kopanya li-ion tsa lithium (Li⁺), ho khothalletsa ho behoa ha junifomo. Liteko li bonts'a hore ho eketsa 2% ho ka theha lesela le boreleli la lithium deposition, 'me bophelo ba potoloho bo eketsoa ho makhetlo a 178 (Li | Li symmetric battery).
(2) Ntlafatsa phetoho ea li-betri tsa lithium-oksijene: Laola sebopeho sa tharollo ea Li⁺, khothalletsa kinetics ea ho bola ea Li₂O₂, 'me u ntlafatse phetoho ea karabelo.
(3) Tšebeliso ea libeteri tsa sodium-ion: Sebelisa mokhoa oa eona o khethiloeng oa Na⁺ ho ntlafatsa katleho ea phetisetso ea sodium.
3. Karohano ea tšepe ea tšepe le ho lemoha
(1) Khetho e ikhethileng: E na le bokhoni bo phahameng ba ho rarahana ba li-cations tse kang Na⁺ le K⁺, 'me e sebelisetsoa:
Phekolo ea metsi a litšila ea li-ion tsa tšepe tse boima (tse kang mercury le uranium).
Ho tsosolosoa ha lisebelisoa tsa radioactive litšila tsa nyutlelie.
(2) Li-sensor tsa electrochemical: Joaloka limolek'hule tse lemohang, e lemoha ka nepo li-ion tse itseng (tse kang K⁺ le Na⁺) maling kapa tikolohong e nang le kutlo e phahameng.
4. Saense ea meriana le thepa
(1) Bajari ba lithethefatsi: Sebelisa biocompatibility ea eona (lintho tse ling tse kang 2-hydroxymethyl-15-crown ether-5) ho finyella phepelo e lebisitsoeng ea lithethefatsi le tokollo e laoloang.
(2) Tokisetso ea metsi a porous: E le mokelikeli o qhibilihisang, o kopantsoeng le li-polyhedrons tsa tšepe (tse kang MOP-18) ho etsa metsi a nang le mocheso oa kamore bakeng sa karohano ea khase kapa polokelo.
5. Lisebelisoa tse ling tsa indasteri
(1) dae synthesis: Ntlafatsa tsela ea karabelo ho ntlafatsa bohloeki ba dae le chai8.
(2) Catalysis ea tšepe ea bohlokoa: E le ligand ho ntlafatsa ts'ebetso le botsitso ba li-catalysts tse kang platinum le palladium, le ho fokotsa palo ea litšepe tsa bohlokoa tse sebelisoang.
