15-Korona-5 CAS 33100-27-5

1. Gawo lothandizira kusintha
(1) Kupititsa patsogolo kaphatikizidwe ka organic: kumapangitsanso kuchuluka kwa zomwe zimachitika komanso zokolola zosasinthika (monga machitidwe amadzi olimba). Mwachitsanzo:
Mu njira ya benzoin condensation, kuwonjezera 7% ya 15-korona etha-5 kungapangitse zokolola kuchokera kutsika kwambiri kufika 78%.
Mu Wurtz lumikiza njira synthesizing silane, kuwonjezera 2% ya 15-korona etha-5 kuonjezera zokolola kuchokera 38,2% kuti 78,8%, ndi kufupikitsa anachita nthawi ndi 3 hours.
(2) Kugwiritsa ntchito mitundu: kuphatikizapo nucleophilic m'malo, redox ndi zitsulo organic zimachitikira, makamaka oyenera zochita za mchere insoluble (monga potaziyamu cyanide) mu solvents organic.
2. Battery electrolyte zowonjezera
(1) Kupondereza ma lithiamu dendrites: Mu lithiamu batire electrolytes, 15-korona ether-5 amachepetsa ion ndende pa electrode pamwamba ndi complexing lithiamu ions (Li⁺), kulimbikitsa yunifolomu deposition. Zoyeserera zikuwonetsa kuti kuwonjezera 2% kumatha kupanga wosanjikiza wosalala komanso wandiweyani wa lithiamu, ndipo moyo wozungulira umakulitsidwa mpaka nthawi 178 (Li | Li symmetric batri).
(2) Sinthani kusinthika kwa mabatire a lithiamu-oksijeni: Sinthani mawonekedwe a Li⁺, limbikitsani kuwonongeka kwa kinetics ya Li₂O₂, ndikuwonjezera kusinthika kwa zomwe zimachitika.
(3) Kugwiritsa ntchito mabatire a sodium-ion: Gwiritsani ntchito mawonekedwe ake osankhidwa a Na⁺ kuti mukwaniritse bwino kufalikira kwa sodium ion.
3. Kupatukana kwachitsulo ndi kuzindikira
(1) Kutulutsa kosankha: Ili ndi kuthekera kosankha kosiyanasiyana kwa ma cation monga Na⁺ ndi K⁺, ndipo imagwiritsidwa ntchito:
Kuyeretsa madzi otayira a ayoni azitsulo zolemera (monga mercury ndi uranium).
Kubwezeretsanso zinthu za radioactive mu zinyalala za nyukiliya.
(2) Masensa a Electrochemical: Monga mamolekyu ozindikira, amazindikira molondola ma ion enieni (monga K⁺ ndi Na⁺) m'magazi kapena chilengedwe chokhala ndi chidwi chachikulu.
4. Sayansi ya zamankhwala ndi zipangizo
(1) Onyamula mankhwala: Gwiritsani ntchito biocompatibility yake (zochokera zina monga 2-hydroxymethyl-15-crown ether-5) kuti mukwaniritse kuperekedwa kwa mankhwala omwe akuwongolera ndikuwongolera kumasulidwa.
(2) Kukonzekera kwa porous zamadzimadzi: Monga zosungunulira khamu, kuphatikiza zitsulo organic polyhedron (monga MOP-18) kupanga firiji porous zamadzimadzi kwa mpweya kulekana kapena kusunga.
5. Ntchito zina zamakampani
(1) Kaphatikizidwe ka utoto: Konzani njira yochitira kuti utoto ukhale woyera komanso zokolola8.
(2) Catalysis yachitsulo chamtengo wapatali: Monga ligand kuti ipititse patsogolo ntchito ndi kukhazikika kwa zinthu monga platinamu ndi palladium, ndi kuchepetsa kuchuluka kwa zitsulo zamtengo wapatali zomwe zimagwiritsidwa ntchito.
