Tswj hwm kev sib raug zoo nrog peb cov neeg siv khoom, peb txawm li cas los xij tsim kho peb cov npe kev daws teeb meem txhua lub sijhawm kom ua tau raws li cov kev xav tau tshiab thiab ua raws li kev txhim kho tshiab tshaj plaws ntawm kev ua lag luam hauv Malta. Peb npaj txhij los ntsib cov teeb meem thiab ua kom zoo dua kom nkag siab txog txhua qhov kev ua tau zoo hauv kev lag luam thoob ntiaj teb.
Cesium carbonate yog ib qho inorganic compound. Nws yog ib qho khoom dawb ntawm chav tsev kub thiab siab. Nws yaj tau zoo heev hauv dej thiab nqus tau cov dej noo sai sai thaum muab tso rau hauv huab cua. Cov kua dej ntawm cesium carbonate yog alkaline heev thiab tuaj yeem ua rau cov kua qaub los tsim cov ntsev cesium thiab dej sib xws, thiab tso cov pa roj carbon dioxide. Cesium carbonate yooj yim hloov pauv thiab tuaj yeem siv ua cov khoom ua ntej ntawm lwm cov ntsev cesium. Nws yog siv dav hauv cov ntsev cesium.

1. Cov tshuaj ua kom cov organic synthesis
1) Cesium carbonate C/N/O-arylation thiab alkylation reactions: Cesium carbonate ua haujlwm ua lub hauv paus muaj zog los txhawb kev hloov pauv ntawm cov nplhaib aromatic lossis heteroatoms, xws li ua kom muaj txiaj ntsig zoo hauv kev sib txuas ntawm cov tshuaj sib txuas36.
2) Cov tshuaj tiv thaiv cyclization: Cesium carbonate yog siv rau rau-membered cyclization, intramolecular lossis intermolecular cyclization, thiab Horner-Emmons cyclization reactions los ua kom yooj yim rau kev tsim cov molecules nyuaj39.
3) Kev tsim cov quinazolinediones thiab cyclic carbonates: Cesium carbonate catalyzes qhov kev cuam tshuam ntawm 2-aminobenzonitrile nrog carbon dioxide los tsim quinazolinediones, lossis synthesizes cyclic carbonates los ntawm halogenated alcohols thiab carbon dioxide36.
2. Cov ntaub ntawv siv rau kev tshawb fawb txog cov ntaub ntawv
1) Cov khoom siv hluav taws xob: Cesium carbonate yog siv los ua txheej xaiv hluav taws xob hauv graphene quantum dots los txhim kho kev ua haujlwm ntawm cov polymer solar cells.
2) Kev npaj cov nanomaterials: Cesium carbonate koom nrog kev tsim cov khoom siv phosphorescent thiab cov hlau organic frameworks (MOFs) los ua kom zoo dua cov khoom siv.
3. Lwm yam kev siv
1) Kev tsim cov tshuaj intermediates: Cesium carbonate yog siv rau hauv cov kauj ruam tseem ceeb ntawm cov 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 zoo thiab txo cov pa phem yam tsis muaj cov hlau hloov pauv lossis cov tshuaj catalysts organic.
