Cesium carbonate CAS 534-17-8
Cesium carbonate ndi mankhwala osakhazikika. Ndi cholimba choyera kutentha ndi kupanikizika. Zimasungunuka kwambiri m'madzi ndipo zimatengera chinyezi mwachangu zikayikidwa mumlengalenga. Madzi amadzimadzi a cesium carbonate ndi amchere kwambiri ndipo amatha kuchitapo kanthu ndi asidi kuti apange mchere wa cesium ndi madzi, ndikutulutsa mpweya woipa. Cesium carbonate ndi yosavuta kusintha ndipo ingagwiritsidwe ntchito ngati kalambulabwalo wa mchere wina wa cesium. Amagwiritsidwa ntchito kwambiri mumitundu yamchere ya cesium.

1. Zothandizira organic synthesis
1) Cesium carbonate C/N/O-arylation ndi alkylation reactions: Cesium carbonate imagwira ntchito ngati maziko amphamvu polimbikitsa kusinthana kwa mphete zokometsera kapena ma heteroatom, monga kukulitsa zokolola pakuphatikizana36.
2) Mayendedwe a cyclization: Cesium carbonate imagwiritsidwa ntchito ngati cyclization ya mamembala asanu ndi limodzi, intramolecular kapena intermolecular cyclization, ndi Horner-Emmons cyclization reactions kuti achepetse kupanga mamolekyu ovuta39.
3) Kaphatikizidwe ka quinazolinediones ndi cyclic carbonates: Cesium carbonate imapangitsa kuti 2-aminobenzonitrile ikhale ndi carbon dioxide kuti ipange quinazolinediones, kapena imapanga cyclic carbonates kupyolera mu mowa wa halogenated ndi carbon dioxide36.
2. Ntchito za sayansi ya Zida
1) Zipangizo zamagetsi: Cesium carbonate imagwiritsidwa ntchito ngati chosanjikiza chosankha ma elekitironi mu madontho a graphene quantum kuti apititse patsogolo mphamvu zama cell a solar solar.
2) Kukonzekera kwa nanomaterials: Cesium carbonate nawo synthesis wa zipangizo phosphorescent ndi zitsulo organic frameworks (MOFs) kukhathamiritsa katundu katundu.
3. Ntchito zina
1) Kaphatikizidwe wa mankhwala intermediates: Cesium carbonate ntchito masitepe ofunika mankhwala umagwirira monga alkylation wa phenols ndi kukonzekera mankwala esters.
2) Zogwirizana ndi chilengedwe: Cesium carbonate imakwaniritsa kutembenuka koyenera ndikuchepetsa kuipitsidwa popanda zitsulo zosinthika kapena organic catalysts.
