Cesium carbonate CAS 534-17-8
Cesium carbonate ke motsoako o sa pheleng. Ke ntho e tiileng e tšoeu mochesong oa kamore le khatellong. E qhibiliha haholo metsing 'me e monya mongobo kapele ha e beoa moeeng. Tharollo ea metsi ea cesium carbonate e na le alkaline e matla 'me e ka arabela le asiti ho hlahisa letsoai le metsi a tsamaellanang le cesium, le ho lokolla carbon dioxide. Cesium carbonate e bonolo ho e fetola 'me e ka sebelisoa e le selelekela sa letsoai le leng la cesium. E sebelisoa haholo mefuteng ea letsoai la cesium.

1. Li-catalyst tsa motsoako oa lintho tse phelang
1) Dikarabelo tsa C/N/O-arylation le alkylation tsa Cesium carbonate: Cesium carbonate e sebetsa e le motheo o matla ho kgothaletsa dikarabelo tsa ho nkela sebaka tsa masale a monko o monate kapa di-heteroatom, tse kang ho eketsa chai dikarabelong tsa ho kopana tse tshekaletseng36.
2) Likarabelo tsa ho potoloha: Cesium carbonate e sebelisetsoa ho potoloha ha limolek'hule ka litho tse tšeletseng, ho potoloha ha limolek'hule ka hare ho limolek'hule kapa ka hare ho limolek'hule, le ho lokisa ha limolek'hule ka hare ho Horner-Emmons ho nolofatsa kaho ea limolek'hule tse rarahaneng39.
3) Ho kopanngoa ha quinazolinediones le cyclic carbonates: Cesium carbonate e susumetsa karabelo ea 2-aminobenzonitrile le carbon dioxide ho hlahisa quinazolinediones, kapa e kopanya cyclic carbonates ka halogenated alcohols le carbon dioxide36.
2. Lisebelisoa tsa mahlale a thepa
1) Lisebelisoa tsa elektroniki: Cesium carbonate e sebelisoa e le lera le khethang lielektrone ka har'a matheba a graphene quantum ho ntlafatsa katleho ea lisele tsa letsatsi tsa polymer.
2) Ho lokisoa ha lintho tse ling tse kang li-nanomaterials: Cesium carbonate e nka karolo ho kopanyeng thepa ea phosphorescent le meralo ea tšepe ea organic (MOFs) ho ntlafatsa thepa ea thepa.
3. Lisebelisoa tse ling
1) Ho kopanngoa ha metsoako e sebetsang ea lithethefatsi: Cesium carbonate e sebelisoa mehatong ea bohlokoa ea k'hemistri ea lithethefatsi joalo ka alkylation ea li-phenol le ho lokisoa ha li-ester tsa phosphate.
2) Likarabelo tse mosa tikolohong: Cesium carbonate e fihlella phetoho e sebetsang hantle mme e fokotsa tšilafalo ntle le litšepe tsa phetoho kapa li-catalyst tsa tlhaho.
