Cesium carbonate CAS 534-17-8
Cesium carbonate waa iskudhis aan organic ahayn. Waa adage cad oo heerkulka qolka iyo cadaadiska. Aad bay ugu milmay biyaha waxayna si degdeg ah u nuugtaa qoyaanka marka hawada la geliyo. Xalka aqueous ee cesium carbonate waa alkaline xoog leh oo waxay la falgali kartaa aashitada si ay u soo saarto milixda iyo biyaha cesium ee u dhiganta, oo ay sii deyso kaarboon laba ogsaydh. Cesium carbonate waa sahlan tahay in la beddelo waxaana loo isticmaali karaa horudhac milixda kale ee cesium. Waxaa si weyn loogu isticmaalaa noocyada cusbada cesium.

1. Aasaaska dabiiciga ah
1) Cesium carbonate C/N/O-arylation iyo falcelinta alkylation: Cesium carbonate waxay u shaqeysaa sidii saldhig xooggan si kor loogu qaado falcelinta beddelka ee giraannada udgoonka ama heteroatoms, sida kordhinta wax-soo-saarka falcelinta isku-dhafka ah36.
2) Dareen-celinta wareegga wareegga: Cesium carbonate waxaa loo isticmaalaa wareegga wareegga lix-xubnood, wareegga molecular ama intermolecular, iyo falcelinta wareegga wareegga Horner-Emmons si loo fududeeyo dhismaha molecules-kakan39.
3) Isku-dhafka quinazolinediones iyo carbonate cyclic: Cesium carbonate waxay kicisaa falcelinta 2-aminobenzonitrile oo leh kaarboon dioxide si ay u soo saarto quinazolinediones, ama isku-darka kaarboonnada wareegyada iyada oo loo marayo alkolada halogenated iyo carbon dioxide36.
2. Codsiyada sayniska agabka
1) Qalabka elektarooniga ah: Cesium carbonate waxaa loo isticmaalaa lakabka xulashada elektarooniga ah ee dhibcaha graphene quantum si kor loogu qaado waxtarka unugyada cadceedda polymer.
2) Diyaarinta nanomaterials: Cesium carbonate waxay ka qaybqaadataa isku-dhafka walxaha fosfooraska iyo qaababka organic organic (MOFs) si kor loogu qaado sifooyinka alaabta.
3. Codsiyada kale
1) Synthesis of intermediates daroogada: Cesium carbonate waxaa loo isticmaalaa in tallaabooyinka muhiimka ah ee kiimikada daroogada sida alkylation of phenols iyo diyaarinta phosphate esters.
2) Dareen-celinta deegaanka saaxiibtinimo: Cesium carbonate waxay ku guulaysataa beddelaad hufan waxayna yaraysaa wasakhowga iyada oo aan lahayn biraha kala-guurka ama kicinta organic.
