Iyini i-Cesium carbonate CAS 534-17-8?

I-Cesium carbonate iyinhlanganisela engeyona into ephilayo. Iyi-solid emhlophe ekushiseni kwegumbi kanye nengcindezi. Incibilika kakhulu emanzini futhi imunca umswakama ngokushesha uma ifakwa emoyeni. Isixazululo samanzi se-cesium carbonate sinamandla kakhulu e-alkaline futhi singasabela ne-asidi ukukhiqiza usawoti we-cesium namanzi ahambisanayo, futhi sikhiphe i-carbon dioxide. I-Cesium carbonate kulula ukuyiguqula futhi ingasetshenziswa njengesandulela sezinye izinsalela ze-cesium. Isetshenziswa kabanzi ezinhlotsheni zikasawoti we-cesium.

Isicelo

1. Ama-catalyst okwenziwa kwezinto eziphilayo
1) I-Cesium carbonate C/N/O-arylation kanye nokusabela kwe-alkylation: I-Cesium carbonate isebenza njengesisekelo esiqinile sokukhuthaza ukusabela kokushintshana kwama-rings aromatic noma ama-heteroatom, njengokwandisa isivuno ekuphenduleni kokuhlangana okuhlanganisiwe36.
2) Ukusabela kwe-cyclization: I-Cesium carbonate isetshenziselwa i-cyclization enamalungu ayisithupha, i-intramolecular noma i-intermolecular cyclization, kanye ne-Horner-Emmons cyclization reactions ukuze kube lula ukwakhiwa kwama-molecule ayinkimbinkimbi39.
3) Ukuhlanganiswa kwama-quinazolinediones nama-cyclic carbonates: I-Cesium carbonate ikhuthaza ukusabela kwe-2-aminobenzonitrile ne-carbon dioxide ukukhiqiza ama-quinazolinediones, noma ihlanganisa ama-cyclic carbonates ngama-halogenated alcohols kanye ne-carbon dioxide36.

2. Izicelo zesayensi yezinto zokwakha
1) Amadivayisi kagesi: I-Cesium carbonate isetshenziswa njengesendlalelo sokukhetha ama-electron kuma-graphene quantum dots ukuthuthukisa ukusebenza kahle kwamaseli elanga e-polymer.
2) Ukulungiswa kwezinto ezisetshenziswayo: I-Cesium carbonate ibamba iqhaza ekuhlanganisweni kwezinto ezisebenzisa i-phosphorescent kanye nezinhlaka ze-metal organic (MOFs) ukuze kuthuthukiswe izakhiwo zezinto.

3. Ezinye izinhlelo zokusebenza
1) Ukwenziwa kwezinto ezihlanganisa izidakamizwa: I-Cesium carbonate isetshenziswa ezinyathelweni ezibalulekile ze-chemistry yezidakamizwa njenge-alkylation yama-phenol kanye nokulungiswa kwama-phosphate esters.
2) Ukusabela okunobungani nemvelo: I-Cesium carbonate ifinyelela ukuguqulwa okuphumelelayo futhi inciphisa ukungcola ngaphandle kwezinsimbi eziguqukayo noma ama-catalyst e-organic.
