Indawo yokubilisa: 333.6 C kwi-760 mmHg
Ukukhanya: DHS 169.8 C
Ukunyibilika kwamanzi: 261 g/100 mL (20 C)
Uzinzo: Uzinzo.Izinto ezingavumelekanga: i-oxidant eyomeleleyo, i-asidi eqinile.
Iimeko zokugcina: indawo yokugcina ingena umoya kwaye yomile kwiqondo lokushisa eliphantsi
| I-Cesium carbonate luhlobo lwe-inorganic compound, oluqinileyo olumhlophe kwiqondo lokushisa kunye noxinzelelo.Inyibilika ngokulula emanzini kwaye ngokukhawuleza i-hygroscopic xa ibekwe emoyeni.Isisombululo se-Cesium carbonate sinamandla e-alkaline, kwaye sinokusabela nge-asidi ukuvelisa ityuwa ye-cesium ehambelanayo kunye namanzi, kwaye ikhuphe i-carbon dioxide.I-Cesium carbonate kufuneka ivalwe, yomiswe kwaye igcinwe ngokwahlukileyo kwi-acids. |
Imisebenzi kunye nezicelo
Iipropathi ezininzi ze-cesium carbonate kwi-organic synthesis zithathwe kwi-soft Lewis acidity ye-cesium ion, eyenza ukuba inyibilike kwii-solvents eziphilayo ezifana ne-alcohols, i-DMF kunye ne-ether.I-solubility engcono kwi-solvents ye-organic yenza ukuba i-cesium carbonate ithathe inxaxheba kwi-chemical reactions catalyzed by palladium reagents njengesiseko esisebenzayo se-inorganic, njenge-Heck, i-Suzuki kunye ne-Sonogashira reactions.Ngokomzekelo, i-Suzuki cross coupling reaction kunye ne-cesium carbonate yakwazi ukufumana isivuno se-86%, ngelixa ukusabela okufanayo kunye ne-sodium carbonate okanye i-triethylamine kuphela i-29% kunye ne-50%.Ngokufanayo, kwi-Heck reaction ye-methacrylate kunye ne-chlorobenzene, i-cesium carbonate xa kuthelekiswa nezinye iziseko ze-inorganic, ezifana ne-potassium carbonate, i-acetate ye-sodium, i-triethylamine, i-potassium phosphate, ibonise inzuzo ecacileyo kakhulu.I-Cesium carbonate nayo inezicelo ezibalulekileyo kwi-o-alkylation ye-phenol compounds.Kucingelwa ukuba i-phenol O-alkylation reaction in cesium carbonate non-aqueous solvent inokuthi ifumane i-phenoxyethylene anion, ngoko ke i-alkylation reaction inokuthi yenzeke kwi-halogenates yesibini kunye nomsebenzi ophezulu kunye nokuphendula okulula kokuphelisa.I-Cesium carbonate nayo inezicelo ezibalulekileyo kwi-synthesis yeemveliso zendalo.Ngokomzekelo, kwi-synthesis ye-Lipogrammistin-ikhompawundi kwi-Inyathelo eliphambili elivaliweyo, i-cesium carbonate njengesiseko se-inorganic ingasetyenziselwa ukufumana iimveliso ezivaliweyo kunye nesivuno esiphezulu.Ukongeza, i-cesium carbonate inezicelo ezibalulekileyo kwiimpendulo ze-organic ezixhaswayo ngenxa yokunyibilika kwayo kakuhle kwizinyibilikisi eziphilayo.I-Carboxylate okanye i-carbamate compounds inokudityaniswa kwisivuno esiphezulu ngokubangela ukuphendulwa kwamacandelo amathathu e-aniline kunye ne-halogen eqinile exhaswayo kwi-carbon dioxide atmosphere.Ngaphantsi kwe-microwave irradiation, i-cesium carbonate inokuphinda isetyenziswe njengesiseko sokuqonda ukusabela kwe-esterification phakathi kwe-benzoic acid kunye neehalojenathi ezixhaswayo eziqinileyo.

ubungakanani.
Umbuzo: Ngaba ubonelela ngeesampulu?isimahla okanye yongeziweyo ?
A: Ewe, sinokunikezela ngesampulu yentlawulo yasimahla kodwa ungahlawuli iindleko zothutho.
Q: Ithini imiqathango yakho yentlawulo?
A: Intlawulo<=1000USD, 100% kwangaphambili.Intlawulo>=1000USD, 30% T/T kwangaphambili,ibhalansi phambi kokuthunyelwa.
