Cov tshuaj aqueous ntawm cesium carbonate yog cov alkaline zoo heev thiab tuaj yeem ua rau cov kua qaub los tsim cov kua ntsev thiab dej, thiab tso cov pa roj carbon dioxide. Cesium carbonate yog ib qho yooj yim los hloov thiab siv tau los ua ib qho precursor ntawm lwm cov ntsev ntsev. Nws yog dav siv nyob rau hauv cesium ntsev ntau yam.

Daim ntawv thov
Ntau yam khoom ntawm cesium carbonate nyob rau hauv cov organic synthesis los ntawm cov mos Lewis acidity ntawm cesium ions, uas ua rau nws soluble nyob rau hauv organic solvents xws li cawv, DMF thiab ether.
Zoo solubility nyob rau hauv cov kuab tshuaj organic enables cesium carbonate los ua ib tug zoo inorganic puag nyob rau hauv palladium reagent-catalyzed tshuaj tiv thaiv xws li Heck, Suzuki thiab Sonogashira cov tshuaj tiv thaiv.
Nws kuj tseem muaj kev siv tseem ceeb hauv kev sib txuas ntawm cov khoom ntuj tsim. Piv txwv li, nyob rau hauv cov kauj ruam tseem ceeb ntawm kaw-ring cov tshuaj tiv thaiv nyob rau hauv lub synthesis ntawm lipogrammistin-A tebchaw, kev siv cov cesium carbonate raws li ib tug inorganic puag yuav tau kaw-ntiv nplhaib cov khoom nyob rau hauv high yield.
Cesium carbonate tuaj yeem siv los ua cov txheej txheem hloov kho ntawm cov txheej txheem nquag thiab Al electrode ntawm lub hnub ci hlwb txhawm rau txhim kho kev hloov pauv ntawm cov khoom siv, tsim cov Al-O-Cs cov tebchaw, txo cov kev ua haujlwm ntawm lub roj teeb, thiab txhim kho qhov luv luv. tam sim no thiab photoelectric conversion efficiency ntawm solar cells.
Tsis tas li ntawd, cesium carbonate muaj ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb, suav nrog tab sis tsis txwv rau kev tsim iav.
