Peb npaj txhij los ntsib cov kev txhawj xeeb thiab ua qhov kev txhim kho kom nkag siab txog txhua qhov muaj peev xwm ua lag luam thoob ntiaj teb.
Cesium carbonate yog ib qho inorganic compound. Nws yog cov khoom dawb ntawm chav tsev kub thiab siab. Nws yog heev soluble nyob rau hauv dej thiab absorbs noo noo sai sai thaum muab tso rau hauv cov huab cua. Cov tshuaj aqueous ntawm cesium carbonate yog cov alkaline thiab tuaj yeem hnov mob nrog cov kua qaub los tsim cov cesium 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.

1. Organic synthesis catalysts
1) Cesium carbonate C / N / O-arylation thiab alkylation cov tshuaj tiv thaiv: Cesium carbonate ua lub hauv paus muaj zog los txhawb kev hloov pauv ntawm cov nplhaib uas muaj ntxhiab lossis heteroatoms, xws li nce cov txiaj ntsig ntawm kev sib txuas sib txuas 36.
2) Cyclization cov tshuaj tiv thaiv: Cesium carbonate yog siv rau 6-membered cyclization, intramolecular los yog intermolecular cyclization, thiab Horner-Emmons cyclization tshwm sim kom yooj yim rau kev tsim kho ntawm complex molecules39.
3) Synthesis ntawm quinazolinediones thiab cyclic carbonates: Cesium carbonate catalyzes cov tshuaj tiv thaiv ntawm 2-aminobenzonitrile nrog carbon dioxide los tsim quinazolinediones, los yog synthesizes cyclic carbonates los ntawm halogenated cawv thiab carbon dioxide36.
2. Cov ntaub ntawv siv science
1) Cov khoom siv hluav taws xob: Cesium carbonate yog siv los ua cov txheej txheem electron nyob rau hauv graphene quantum dots los txhim kho cov kev ua tau zoo ntawm cov hnub ci polymer.
2) Kev npaj ntawm nanomaterials: Cesium carbonate koom nyob rau hauv cov synthesis ntawm phosphorescent cov ntaub ntawv thiab hlau organic moj khaum (MOFs) kom optimize cov khoom vaj tse.
3. Lwm yam kev siv
1) Synthesis of drug intermediates: Cesium carbonate yog siv nyob rau hauv cov kauj ruam tseem ceeb ntawm tshuaj chemistry xws li alkylation ntawm phenols thiab kev npaj ntawm phosphate esters.
2) Cov tshuaj tiv thaiv ib puag ncig: Cesium carbonate ua tiav kev hloov pauv tau zoo thiab txo cov pa phem yam tsis muaj kev hloov pauv hlau lossis cov organic catalysts.
