Chii chinonzi Potassium tert-butoxide CAS 865-47-4?

Potassium tert-butoxide inokosha organic base ine alkalinity yakakwira kupfuura potassium hydroxide. Nekuda kweiyo inductive mhedzisiro yeatatu methyl mapoka e (CH3) 3CO-, ine akasimba alkalinity uye chiitiko kupfuura mamwe potassium alcoholates, saka yakanaka catalyst. Pamusoro pezvo, sehwaro hwakasimba, potassium tert-butoxide inoshandiswa zvakanyanya mukugadzirwa kweorganic senge indasitiri yemakemikari, mushonga, mushonga wezvipembenene, nezvimwewo, senge transesterification, condensation, rearrangement, polymerization, kuvhura mhete uye kugadzirwa kweheavy metal orthoesters. Inogona kushandiswa kukonzeresa Michael kuwedzera reaction, Pinacol rearrangement reaction uye Ramberg-Backlund rearrangement reaction; potassium tert-butoxide inoshandiswa sechinhu chinogadzirisa kugadzirisa Darzens condensation reaction uye Stobbe condensation reaction; iyo zvakare ndiyo inonyanya kushanda hwaro hwechinyakare alkoxide-haloform reaction yekugadzira dihalocarbene. Naizvozvo, potassium tert-butoxide iri kuwedzera kufarirwa neindasitiri yemakemikari, mushonga, mushonga wezvipembenene uye mamwe maindasitiri. Potassium tert-butoxide ine huwandu hwakawanda hwekushandisa, saka pane kudiwa kukuru kwepamusoro-kuchena potassium tert-butoxide kumba nekune dzimwe nyika. Zvisinei, sezvo mari yekugadzira yakakwira kupfuura yemamwe alkali metal alcoholates uye tekinoroji yekugadzira inoda kuvandudzwa, tsvakiridzo yakadzama pamusoro pe potassium tert-butoxide inonyanya kukosha.

Application

Potassium tert-butoxide inoshandiswa zvakanyanya mukugadzirwa kwemakemikari senge indasitiri yemakemikari, mushonga, mushonga wezvipembenene, nezvimwewo.

1. Transesterification reaction: Inoshandiswa kuita transesterification reaction mune organic synthesis kugadzira ester makomisheni matsva.

2. Condensation reaction : Semumiririri wecondensation, inotora chikamu muDarzens condensation reaction, Stobbe condensation reaction, nezvimwe.

3. Rearrangement reaction: Inokonzeresa kuita kwaMichael kuwedzera, Pinacol rearrangement reaction uye Ramberg-Backlund rearrangement reaction.

4. Mhete-yekuvhura maitiro: Inoita sechinhu chinokonzeresa mukuvhura-mhete kusimudzira kuvhura-kuvhurwa kwema cyclic makomisheni.

5. Polymerization reaction: Inotora chikamu mukuita kwepolymerization kugadzirira makomisheni epolymer.

6. Kugadzirira kweheavy metal orthoesters: Inoshandiswa kugadzirira heavy metal orthoesters
