Cesium carbonate CAS 534-17-8
Cesium carbonate wani fili ne na inorganic. Fari ne mai ƙarfi a zafin jiki da matsa lamba. Yana da narkewa sosai a cikin ruwa kuma yana ɗaukar danshi da sauri idan an sanya shi cikin iska. Maganin ruwa na cesium carbonate yana da ƙarfi alkaline kuma yana iya amsawa da acid don samar da gishiri da ruwa daidai cesium, kuma ya saki carbon dioxide. Cesium carbonate yana da sauƙin canzawa kuma ana iya amfani dashi azaman mafarin sauran gishirin cesium. Ana amfani dashi sosai a cikin nau'in gishiri na ceium.

1. Organic kira catalysts
1) Cesium carbonate C / N / O-arylation da halayen alkylation: Cesium carbonate yana aiki azaman tushe mai ƙarfi don haɓaka halayen canji na zoben aromatic ko heteroatoms, kamar haɓaka yawan amfanin ƙasa a cikin halayen haɗin kai36.
2) Halayen cyclization: Ana amfani da Cesium carbonate don hawan keke mai membobi shida, intramolecular ko intermolecular cyclization, da Horner-Emmons cyclization halayen don sauƙaƙe ginin hadaddun kwayoyin39.
3) Maganar quinazolinediones da cyclic carbonates: Cesium carbonate catalyzes da dauki na 2-aminobenzonitrile tare da carbon dioxide don samar da quinazolinediones, ko synthesizes cyclic carbonates ta halogenated alcohols da carbon dioxide36.
2. Aikace-aikacen kimiyyar kayan aiki
1) Na'urorin Lantarki: Ana amfani da Cesium carbonate azaman zaɓin zaɓi na lantarki a cikin ɗigon ƙira na graphene don haɓaka haɓakar ƙwayoyin polymer na hasken rana.
2) Shiri na nanomaterials: Cesium carbonate shiga cikin kira na phosphorescent kayan da karfe Organic frameworks (MOFs) don inganta kayan Properties.
3. Sauran aikace-aikace
1) Rubutun magungunan miyagun ƙwayoyi: Ana amfani da Cesium carbonate a cikin mahimman matakan sunadarai na miyagun ƙwayoyi kamar alkylation na phenols da shirye-shiryen phosphate esters.
2) Halayen abokantaka na muhalli: Cesium carbonate yana samun ingantaccen juzu'i kuma yana rage gurɓataccen gurɓataccen ƙarfe ba tare da ƙarafa ba ko abubuwan haɓakawa.
