Yintoni iCesium carbonate CAS 534-17-8?

I-Cesium carbonate yikhompawundi engaphiliyo. Yinto emhlophe eqinileyo kubushushu begumbi kunye noxinzelelo. Inyibilika kakhulu emanzini kwaye ifunxa umswakama ngokukhawuleza xa ibekwe emoyeni. Isisombululo samanzi se-cesium carbonate sinamandla e-alkaline kwaye sinokusabela kunye ne-asidi ukuvelisa ityuwa ye-cesium ehambelanayo kunye namanzi, kwaye ikhuphe i-carbon dioxide. I-Cesium carbonate kulula ukuyiguqula kwaye ingasetyenziswa njengomzekelo wezinye iityuwa ze-cesium. Isetyenziswa kakhulu kwiintlobo zetyuwa ye-cesium.

Isicelo

1. Iikhatalyst zokwenziwa kwezinto eziphilayo
1) I-Cesium carbonate C/N/O-arylation kunye neempendulo ze-alkylation: I-Cesium carbonate isebenza njengesiseko esomeleleyo sokukhuthaza iimpendulo zokutshintshwa kweeringi ze-aromatic okanye ii-heteroatom, njengokunyusa isivuno kwiimpendulo ezidibeneyo36.
2) Iimpendulo ze-cyclization: I-Cesium carbonate isetyenziselwa i-cyclization enamalungu amathandathu, i-intramolecular okanye i-intermolecular cyclization, kunye neempendulo ze-Horner-Emmons cyclization ukwenza lula ukwakhiwa kwee-molecules ezintsonkothileyo39.
3) Ukwenziwa kwe-quinazolinediones kunye ne-cyclic carbonates: I-Cesium carbonate ikhuthaza ukusabela kwe-2-aminobenzonitrile kunye ne-carbon dioxide ukuvelisa i-quinazolinediones, okanye idibanisa ii-cyclic carbonates ngokusebenzisa ii-halogenated alcohols kunye ne-carbon dioxide36.

2. Usetyenziso lwesayensi yezinto zokwakha
1) Izixhobo ze-elektroniki: I-Cesium carbonate isetyenziswa njengomaleko okhetha i-electron kwiidots ze-graphene quantum ukuphucula ukusebenza kakuhle kweeseli zelanga ze-polymer.
2) Ukulungiswa kwezinto ezisetyenziswa kwi-nanomaterials: I-Cesium carbonate ithatha inxaxheba ekuhlanganisweni kwezinto ezisebenzisa i-phosphorescent kunye ne-metal organic frameworks (MOFs) ukuze kuphuculwe iipropati zezinto.

3. Ezinye izicelo
1) Ukwenziwa kwezinto ezidityanisiweyo namayeza: I-Cesium carbonate isetyenziswa kumanyathelo abalulekileyo kwikhemistri yamayeza afana nokuxuba ii-phenols kunye nokulungiselela ii-phosphate esters.
2) Iimpendulo ezinobuhlobo nokusingqongileyo: I-Cesium carbonate ifikelela ekuguqulweni okusebenzayo kwaye inciphisa ungcoliseko ngaphandle kweentsimbi eziguqukayo okanye ii-catalysts ze-organic.
