Kwifektri ithengisa kakhulu i-Organic Raw Materials Cesium Carbonate CAS 534-17-8
Siye sagxila ekuphuculeni ulawulo lwezinto kunye nenkqubo ye-QC ukuqinisekisa ukuba singabamba inzuzo emangalisayo kwishishini elikhuphisana ngokuqatha kwiFactory ethengisa kakhulu i-Organic Raw Materials Cesium Carbonate CAS 534-17-8, Ngoku sinezinto ezine eziphambili. Izinto zethu zokuthengisa azithengiswa kuphela ngaphakathi kwimarike yangoku yaseTshayina, kodwa zamkelwe nakwimarike yamazwe ngamazwe.
Besijonge ekuphuculeni ulawulo lwezinto kunye nenkqubo ye-QC yokuqinisekisa ukuba singabamba inzuzo entle kwishishini elikhuphisana ngokuqatha, Sigxininisa kulawulo olukumgangatho ophezulu wesizukulwana kunye noncedo lwepro yabathengi, ngoku siyile isisombululo sethu ukubonelela abathengi bethu sisebenzisa ukuqalisa ngexabiso lokufumana nasemva kweenkonzo ngamava asebenzayo. Ukugcina ubudlelwane obukhoyo kunye nabathengi bethu, nangona kunjalo sivelisa uluhlu lwethu lwezisombululo ngalo lonke ixesha ukwanelisa iimfuno ezintsha kraca kunye nokubambelela kuphuhliso lwangoku lwemarike yaseMalta. Sikulungele ukujongana namaxhala kwaye senze ukuphucula ukuqonda konke okunokwenzeka kurhwebo lwamazwe ngamazwe.
I-Cesium carbonate yi-inorganic compound. Iqinile emhlophe kwiqondo lokushisa kunye noxinzelelo. Inyibilika kakhulu emanzini kwaye ifunxa ukufuma ngokukhawuleza xa ibekwe emoyeni. Isisombululo esinamanzi se-cesium carbonate sinamandla e-alkaline kwaye sinokusabela nge-asidi ukuvelisa ityuwa ye-cesium ehambelanayo kunye namanzi, kunye nokukhulula i-carbon dioxide. I-Cesium carbonate kulula ukuyiguqula kwaye ingasetyenziswa njenge-precursor yezinye iityuwa ze-cesium. Isetyenziswa kakhulu kwiintlobo zetyuwa ye-cesium.

1. Ii-catalysts ze-Organic synthesis
I-1) I-Cesium carbonate C / N / O-arylation kunye ne-alkylation reactions: I-Cesium carbonate isebenza njengesiseko esomeleleyo sokukhuthaza ukuphendulwa kokutshintshwa kwamakhonkco amnandi okanye i-heteroatoms, njengokwandisa isivuno kwiimpendulo zokudibanisa36.
2) Iimpendulo ze-Cyclization: I-Cesium carbonate isetyenziselwa i-cyclization yamalungu amathandathu, i-intramolecular okanye i-intermolecular cyclization, kunye neempendulo ze-cyclization ye-Horner-Emmons ukwenza lula ukwakhiwa kwee-molecule eziyinkimbinkimbi39.
I-3) I-synthesis ye-quinazolinediones kunye ne-cyclic carbonates: I-Cesium carbonate i-catalyzes ukuphendula kwe-2-aminobenzonitrile kunye ne-carbon dioxide ukuvelisa i-quinazolinediones, okanye i-synthesizes carbonates ye-cyclic ngokusebenzisa i-alcohol e-halogenated kunye ne-carbon dioxide36.
2. Ukusetyenziswa kwenzululwazi yeMathiriyeli
I-1) Izixhobo zombane: I-Cesium carbonate isetyenziswe njengoluhlu olukhethiweyo lwe-electron kwi-graphene quantum dots ukuphucula ukusebenza kakuhle kweeseli zelanga ze-polymer.
I-2) Ukulungiswa kwama-nanomaterials: I-Cesium carbonate ithatha inxaxheba kwi-synthesis ye-phosphorescent materials kunye ne-metal organic frameworks (MOFs) ukuze kulungiswe izinto eziphathekayo.
3. Ezinye izicelo
I-1) I-synthesis ye-intermediates yeziyobisi: I-Cesium carbonate isetyenziselwa amanyathelo aphambili ekhemistri yeziyobisi ezifana ne-alkylation ye-phenols kunye nokulungiswa kwe-phosphate esters.
2) Ukuphendula okusingqongileyo: I-Cesium carbonate ifezekisa ukuguqulwa okusebenzayo kunye nokunciphisa ukungcola ngaphandle kweentsimbi zenguqu okanye i-organic catalysts.
