15-Crown-5 CAS 33100-27-5

1. Soo kicinta wareejinta wejiga
(1) Isku-dhafka dabiiciga ah ee la xoojiyey: wuxuu si weyn u wanaajiyaa heerka falcelinta wuxuuna soo saaraa fal-celinno kala duwan (sida nidaamyada wejiga adag ee dareeraha ah). Tusaale ahaan:
Dareen-celinta uumiga benzoin, ku darida 7% ee 15-crown ether-5 waxay kordhin kartaa wax-soo-saarka mid aad u hooseeya ilaa 78%.
Habka isku-xidhka Wurtz ee isku-dhafka silane, ku darista 2% ee 15-crown ether-5 waxay kordhin kartaa wax-soo-saarka 38.2% ilaa 78.8%, waxayna soo gaabin kartaa wakhtiga falcelinta 3 saacadood.
(2) Noocyada falcelinta lagu dabaqi karo: oo ay ku jiraan beddelka nucleophilic, redox iyo falcelinta organic birta, gaar ahaan ku habboon falcelinta milixda aan milmi karin (sida cyanide potassium) ee dareerayaasha organic.
2. wax lagu daro baytariga korantada
(1) Xakamaynta lithium dendrites: Batariyada lithium ee elektirolytka, 15-crown ether-5 waxay yaraynaysaa fiirsashada ion ee dusha sare ee korantada iyadoo isku dhafan lithium ions (Li⁺), kor u qaadaysa dhigaalka lebbiska ah. Tijaabooyinku waxay muujinayaan in ku darista 2% ay samayn karto lakab lithium ah oo siman oo cufan, iyo nolosha meertada ayaa la kordhiyey ilaa 178 jeer (Li | Li symmetric baturi).
(2) Hagaajinta beddelka baytariyada lithium-oxygen: nidaami qaab dhismeedka xallinta Li⁺, kor u qaadida kala-goynta kinetics ee Li₂O₂, oo kor u qaadka rogidda falcelinta.
(3) Codsiga baytariyada sodium-ion: Ka faa'iidayso qaabkeeda xulashada ee Na⁺ si aad u wanaajiso waxtarka gudbinta ion sodium.
3. Kala saarista iyo ogaanshaha ion birta
(1) Soosaar Xulasho: Waxa ay leedahay karti kala-doorasho saraysa oo loogu talagalay cations sida Na⁺ iyo K⁺, waxaana loo isticmaalaa:
Daawaynta biyaha wasakhda ah ee biraha culus (sida meerkuri iyo uranium).
Soo kabashada walxaha shucaaca ee qashinka nukliyeerka.
(2) Dareemayaasha Electrochemical: Unugyada aqoonsiga, waxay si sax ah u ogaadaan ion gaar ah (sida K⁺ iyo Na⁺) ee dhiiga ama deegaanka leh dareen sare.
4. Cilmiga daawada iyo agabka
(1) Qaadayaasha maandooriyaha: Ka faa'iidayso laqabsigeeda (qaar ka mid ah derivatives sida 2-hydroxymethyl-15-crown ether-5) si loo gaaro gaarsiinta daroogada ee la beegsaday iyo sii deynta la xakameeyey.
(2) Diyaarinta dareerayaasha daloolka leh: Sida martigeliyaha dareeraha ah, oo lagu daray biraha polyhedrons organic (sida MOP-18) si ay u sameeyaan dareeraha heerkulka qolka ee kala soocida gaaska ama kaydinta.
5. Codsiyada kale ee warshadaha
(1) Isku-dhafka dheeha: Wanaaji dariiqa falcelinta si loo hagaajiyo nadiifnimada dheeha iyo dhalidda8.
(2) Qalabka birta qaaliga ah: Sida ligand si kor loogu qaado dhaqdhaqaaqa iyo xasiloonida kicinta sida platinum iyo palladium, iyo dhimista qadarka birta qaaliga ah ee la isticmaalo.
