Chii chinonzi 15-Crown-5 CAS 33100-27-5?

15-Crown ether-5 imvura isina ruvara, yakajeka, viscous inotora hunyoro nyore uye inosanganiswa nemvura. Inonyungudika muorganic solvents senge ethanol, benzene, chloroform, uye dichloromethane. Iine simba rakasimba rekusarudza kugadzirwa kwesodium ions uye inoshanda yekufambisa chikamu catalyst uye yakaoma mumiriri.

Application

1. Phase transfer catalyst
(1) Enhanced organic synthesis: inovandudza zvakanyanya chiyero chekuita uye goho mune heterogeneous maitiro (akadai semvura-yakasimba chikamu masisitimu). Semuyenzaniso:
Mune benzoin condensation reaction, kuwedzera 7% ye15-crown ether-5 inogona kuwedzera goho kubva pakaderera zvikuru kusvika pa78%.
MuWurtz coupling nzira yekugadzira silane, kuwedzera 2% ye15-crown ether-5 inogona kuwedzera goho kubva pa38.2% kusvika 78.8%, uye kupfupisa nguva yekuita nemaawa matatu.
(2) Anoshanda maitiro emhando: kusanganisira nucleophilic substitution, redox uye simbi organic reactions, kunyanya yakakodzera maitiro einsoluble munyu (senge potassium cyanide) mune organic solvents.
2. Battery electrolyte additive
(1) Kudzvinyirira lithium dendrites: Mu lithium battery electrolytes, 15-crown ether-5 inoderedza ion concentration pa electrode surface kuburikidza nekugadzirisa lithium ions (Li⁺), kukurudzira yunifomu deposition. Ongororo dzinoratidza kuti kuwedzera 2% kunogona kuumba yakatsetseka uye dense lithium deposition layer, uye hupenyu hwekutenderera hunowedzerwa kusvika 178 times (Li | Li symmetric bhatiri).
(2) Kuvandudza kudzoreredzwa kwemabhatiri e-lithium-oxygen: Rongedza iyo solvation chimiro cheLi⁺, kusimudzira decomposition kinetics yeLi₂O₂, uye kuwedzera kudzoreredzwa kwemaitiro.
(3) Kushandiswa kwemabhatiri e-sodium-ion: Shandisa iyo yakasarudzika yakaoma yeNa⁺ kuti uwedzere iyo sodium ion kutapurirana zvakanaka.
3. Metal ion kuparadzaniswa uye kuonekwa
(1) Sarudzo yekubvisa: Iine yakakwirira yekusarudza kuomarara kugona kwema cations akadai saNa⁺ uye K⁺, uye inoshandiswa ku:
Kugadziriswa kwemvura yakasviba yeheavy metal ions (senge mercury uye uranium).
Kudzoreredzwa kweradioactive element mumarara enyukireya.
(2) Electrochemical sensors: Semamorekuru ekuzivikanwa, inonyatsoona maion chaiwo (akadai seK⁺ neNa⁺) muropa kana nharaunda ine kunzwa kwakanyanya.
4. Mushonga uye zvinhu sainzi
(1) Vatakuri vezvinodhaka: Shandisa biocompatibility yayo (zvimwe zvinobva senge 2-hydroxymethyl-15-crown ether-5) kuti uwane yakanangwa zvinodhaka kuendesa uye kudzorwa kuburitswa.
(2) Kugadzirira kwezvinwiwa zvine porous: Sezvinonyungudutsa, zvakasanganiswa nesimbi organic polyhedron (seMOP-18) kugadzira tembiricha yekamuri porous zvinwiwa zvekuparadzanisa gasi kana kuchengetedza.
5. Mamwe maindasitiri ekushandisa
(1) Dhayi synthesis: Optimize maitiro ekuita nzira yekuvandudza dhayi kuchena uye goho8.
(2) Yakakosha simbi catalysis: Se ligand yekusimudzira chiitiko uye kugadzikana kwezvinokonzeresa senge platinum uye palladium, uye kuderedza huwandu hwemasimbi anokosha anoshandiswa.
