Kev ua haujlwm nyuaj kom ua tiav, kev tsim kho tshiab hauv kev lag luam, ua txhua yam rau kev lag luam thawj zaug. Peb sim peb qhov zoo tshaj plaws los tsim cov qauv kev tswj hwm kev tshawb fawb, kawm paub ntau yam txuj ci, tsim cov khoom siv ntau lawm thiab cov txheej txheem ntau lawm, los tsim cov kev daws teeb meem thawj zaug, tsim nyog tus nqi, kev pabcuam zoo, xa khoom sai, muab koj tsim tus nqi tshiab.
Dibenzo-18-crown-6yog cov khoom siv raw rau kev sib txuas ntawm diaminodibenzo-18-crown-6. Diaminodibenzo-18-crown-6 yog ib qho tseem ceeb crown ether compound thiab ib qho tseem ceeb nruab nrab raw khoom rau cov synthesis ntawm crown ether derivatives. Nws txoj kev sib txuas yog siv dibenzo-18-crown-6 raws li cov khoom siv raw, thiab tau txais los ntawm nitration thiab txo cov tshuaj tiv thaiv. Txoj kev txo qis siv yog Pd / C txo txoj kev, uas yog txwv los ntawm tus nqi catalyst kim. Cov txheej txheem kev sib xyaw ua ke ntawm dibenzo-18-crown-6, cov khoom siv raw ntawm diaminodibenzo-18-crown-6, yog cov tshuaj tiv thaiv reflux nyob rau hauv kev tiv thaiv nitrogen, uas muaj cov xwm txheej hnyav, cov kauj ruam nyuaj, lub voj voog ntev, kev kub siab thiab tsis tshua muaj txiaj ntsig. Ultrasonic synthesis yog ib hom tshiab ntawm synthesis txoj kev tsim nyob rau hauv xyoo tas los no. Nws muaj qhov zoo ntawm kev coj zoo, lub zog loj thiab muaj peev xwm nkag mus tau zoo. Nws yog qhov yooj yim dua thiab yooj yim rau kev khiav lag luam dua li cov txheej txheem organic synthesis. Cov cuab yeej siv sim no kuj yog qhov yooj yim thiab yooj yim los tswj. Nws yog ntau thiab ntau dav siv nyob rau hauv cov organic synthesis.

1. Hlau ion complexing tus neeg sawv cev:Dibenzo-18-crown-6tuaj yeem tsim cov complexes ruaj khov nrog alkali hlau ions (xws li potassium thiab sodium) thiab feem ntau yog siv rau hauv kev rho tawm thiab sib cais ntawm cov hlau ions. Piv txwv li, nws muaj peev xwm complex nrog poov tshuaj ions los txhawb lub extraction thiab sib cais ntawm ntsev.
2. Theem hloov catalyst:Dibenzo-18-crown-6ua raws li theem hloov catalyst hauv cov organic catalytic cov tshuaj tiv thaiv los txhawb kev ua haujlwm thiab tawm los ntawm ob-theem cov tshuaj tiv thaiv. Piv txwv li, nws yog siv nyob rau hauv lub synthesis ntawm monoazaporphyrins thiab ion transmembrane migration 23.
3. Ion sensor : Cov khoom sib xyaw ua ke raws li Dibenzo-18-crown-6 tuaj yeem siv los npaj cov ion sensors los kuaj xyuas thiab ntsuas qhov muaj thiab concentration ntawm cov ions tshwj xeeb.
4. Tshuaj tsom xam: Dibenzo-18-crown-6 yog siv rau hauv extraction thiab sib cais txheej txheem hauv analytical chemistry los extract thiab enrich lub hom phiaj tebchaw los yog hlau ions rau tom ntej no tsom xam thiab nrhiav kom tau
