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

I-Cesium carbonate iyinhlanganisela ye-inorganic. Iqinile emhlophe ekushiseni kwekamelo kanye nokucindezela. Incibilika kakhulu emanzini futhi imunca umswakama ngokushesha lapho ibekwe emoyeni. Isixazululo esinamanzi se-cesium carbonate sine-alkaline enamandla futhi singasabela nge-asidi ukuze sikhiqize usawoti ohambisanayo we-cesium namanzi, futhi sikhiphe isikhutha. I-cesium carbonate kulula ukuyiguqula futhi ingasetshenziswa njengesandulela sabanye usawoti we-cesium. Isetshenziswa kabanzi ezinhlobonhlobo zikasawoti we-cesium.

Isicelo

1. Ama-catalyst e-Organic synthesis
I-1) I-Cesium carbonate C/N/O-arylation kanye nokusabela kwe-alkylation: I-Cesium carbonate isebenza njengesisekelo esiqinile sokukhuthaza ukusabela okushintshwayo kwamandandatho anephunga elimnandi noma ama-heteroatom, njengokwandisa isivuno ekuphenduleni kokuhlanganisa36.
2) Ukusabela kokuhamba ngebhayisikili: I-Cesium carbonate isetshenziselwa ukujikeleza kwama-cyclization onamalungu ayisithupha, i-intramolecular noma i-intermolecular cyclization, kanye nokusabela kwe-cyclization ye-Horner-Emmons ukuze kube lula ukwakhiwa kwama-molecule39.
I-3) Ukuhlanganiswa kwe-quinazolinediones nama-cyclic carbonates: I-Cesium carbonate ivuselela ukusabela kwe-2-aminobenzonitrile nge-carbon dioxide ukukhiqiza i-quinazolinediones, noma ihlanganise ama-cyclic carbonates ngokusebenzisa utshwala obu-halogenated ne-carbon dioxide36.

2. Izicelo zesayensi yezinto ezibonakalayo
1) Imishini kagesi: I-Cesium carbonate isetshenziswa njengesendlalelo esikhethiwe se-electron kumachashazi we-graphene quantum ukuthuthukisa ukusebenza kahle kwamaseli elanga e-polymer.
2) Ukulungiswa kwama-nanomaterials: I-Cesium carbonate ibamba iqhaza ekuhlanganiseni izinto ze-phosphorescent kanye nezinhlaka ze-metal organic (MOFs) ukuze kuthuthukiswe izakhiwo zezinto ezibonakalayo.

3. Ezinye izinhlelo zokusebenza
1) Ukuhlanganiswa kwezidakamizwa ezimaphakathi: I-Cesium carbonate isetshenziswa ezinyathelweni ezibalulekile zekhemikhali yezidakamizwa njenge-alkylation yama-phenols kanye nokulungiswa kwama-phosphate esters.
2) Ukusabela okulungele imvelo: I-Cesium carbonate izuza ukuguqulwa okuphumelelayo futhi inciphisa ukungcoliswa ngaphandle kwezinsimbi eziguqukayo noma ama-organic catalysts.
