Cesium carbonate CAS 534-17-8
Cesium carbonate ndi chinthu chosapangidwa ndi zinthu zachilengedwe. Ndi chinthu choyera cholimba kutentha kwa chipinda ndi kupanikizika. Chimasungunuka kwambiri m'madzi ndipo chimayamwa chinyezi mwachangu chikayikidwa mumlengalenga. Madzi a cesium carbonate ndi amchere kwambiri ndipo amatha kuchitapo kanthu ndi asidi kuti apange mchere wofanana wa cesium ndi madzi, ndikutulutsa carbon dioxide. Cesium carbonate ndi yosavuta kusintha ndipo ingagwiritsidwe ntchito ngati choyambira cha mchere wina wa cesium. Imagwiritsidwa ntchito kwambiri mumitundu ya mchere wa cesium.

1. Zosakaniza zachilengedwe
1) Cesium carbonate C/N/O-arylation ndi alkylation reactions: Cesium carbonate imagwira ntchito ngati maziko olimba olimbikitsira kusintha kwa mphete za aromatic kapena heteroatoms, monga kuwonjezera phindu mu cross-coupling reactions36.
2) Machitidwe a cyclization: Cesium carbonate imagwiritsidwa ntchito pa cyclization ya ziwalo zisanu ndi chimodzi, intramolecular kapena intermolecular cyclization, ndi Horner-Emmons cyclization reactions kuti zikhale zosavuta kumanga mamolekyu ovuta39.
3) Kupanga kwa quinazolinediones ndi cyclic carbonates: Cesium carbonate imayambitsa momwe 2-aminobenzonitrile imagwirira ntchito ndi carbon dioxide kuti ipange quinazolinediones, kapena imapanga cyclic carbonates kudzera mu halogenated alcohols ndi carbon dioxide36.
2. Kugwiritsa ntchito sayansi ya zipangizo
1) Zipangizo zamagetsi: Cesium carbonate imagwiritsidwa ntchito ngati gawo losankha ma electron mu ma graphene quantum dots kuti iwonjezere magwiridwe antchito a ma cell a dzuwa a polymer.
2) Kukonzekera zinthu zopangidwa ndi nanomaterials: Cesium carbonate imagwira ntchito popanga zinthu zopangidwa ndi phosphorescent ndi zitsulo zopangidwa ndi organic (MOFs) kuti ziwonjezere mphamvu za zinthu.
3. Ntchito zina
1) Kupanga zinthu zosakaniza mankhwala: Cesium carbonate imagwiritsidwa ntchito mu njira zofunika kwambiri pakupanga mankhwala monga alkylation ya phenols ndi kukonzekera ma phosphate esters.
2) Zochita zosamalira chilengedwe: Cesium carbonate imapangitsa kuti zinthu zisinthe bwino komanso imachepetsa kuipitsa chilengedwe popanda zitsulo zosinthika kapena zinthu zoyambitsa zinthu zachilengedwe.
