Poindi yekubikira: 333.6 C pa760 mmHg
Kupenya: DHS 169.8 C
Kunyungudika kwemvura: 261 g/100 mL (20 C)
Kugadzikana: Kugadzikana.Zvinhu zvakarambidzwa: yakasimba oxidant, asidhi yakasimba.
Mamiriro ekuchengetedza: imba yekuchengetera inofefetera uye yakaoma pakupisa kwakadzika
| Cesium carbonate imhando yeinorganic compound, iyo chena yakasimba pakupisa kwekamuri uye kumanikidza.Inonyungudika nyore mumvura uye inokurumidza hygroscopic kana yakaiswa mumhepo.Cesium carbonate solution ine alkaline yakasimba, uye inogona kuita neasidhi kugadzira inowirirana cesium munyu nemvura, uye inobudisa carbon dioxide.Cesium carbonate inofanira kuvharwa, yakaomeswa uye kuchengetwa zvakasiyana kubva kune acids. |
Mabasa uye Applications
PrMany zvimiro zve cesium carbonate mune organic synthesis inotorwa kubva kune yakapfava Lewis acidity yecesium ion, iyo inoita kuti inyungudika muzvinonyungudutsa organic senge doro, DMF uye ether.Iko kunyungudika kuri nani mumakemikari zvinonyungudutsa kunoita kuti cesium carbonate itore chikamu mumakemikari anokonzerwa ne palladium reagents senge inoshanda inorganic base, senge Heck, Suzuki uye Sonogashira maitiro.Semuenzaniso, Suzuki cross coupling reaction necesium carbonate yakakwanisa kuwana 86% goho, ukuwo maitiro akafanana ne sodium carbonate kana triethylamine yaingova 29% uye 50%.Saizvozvowo, muHeck reaction ye methacrylate uye chlorobenzene, cesium carbonate ichienzaniswa nemamwe mabhesi e-inorganic, akadai se potassium carbonate, sodium acetate, triethylamine, potassium phosphate, yakaratidza mukana wakajeka zvikuru.Cesium carbonate inewo zvakakosha zvinoshandiswa mu-o-alkylation ye phenol compounds.Zvinofungidzirwa kuti phenol O-alkylation reaction mu cesium carbonate isiri-aqueous solvent inogona kusangana ne phenoxyethylene anion, saka iyo alkylation reaction inogonawo kuitika kune yechipiri halogenates ine basa rakakwirira uye nyore kubvisa kugadzirisa.Cesium carbonate ine zvakare yakakosha maapplication mumubatanidzwa wezvigadzirwa zvechisikigo.Semuenzaniso, mukugadzirwa kweLipogrammistin-mushonga muA kiyi nhanho yakavharwa-loop reaction, cesium carbonate senge inorganic base inogona kushandiswa kuwana yakavharwa-loop zvigadzirwa zvine goho rakakura.Pamusoro pezvo, cesium carbonate ine yakakosha maapplication mune yakasimba yakatsigirwa organic reactions nekuda kwekunyungudika kwayo kwakanaka muorganic solvents.Carboxylate kana carbamate makomboni anogona kugadzirwa pagoho repamusoro nekukurudzira kuita kwezvikamu zvitatu zveaniline ine halogen yakasimba inotsigirwa mumhepo yecarbon dioxide.Pasi pe microwave irradiation, cesium carbonate inogona zvakare kushandiswa senheyo yekuona esterification reaction pakati pe benzoic acid uye yakasimba yakatsigirwa halogenates.

Q: Iwe unopa samples here?ndeyemahara here kana kuwedzera?
A: Hongu, tinogona kupa sampuli yemahara asi hatibhadhare mutengo wekutakura.
Q: Ndeapi mazwi ako ekubhadhara?
A: Kubhadhara<=1000USD, 100% pachine nguva.Kubhadhara> = 1000USD, 30% T/T pachine nguva, yasara isati yatumirwa.
