Mawu Oyamba
3. asidi pinacol ester ndi organic pawiri ndi mankhwala chilinganizo C12H19BO3 ndi molecular kulemera kwa 214.09g/mol.
Chilengedwe:
-Maonekedwe: Madzi opanda mtundu kapena olimba
- Malo osungunuka: -43 ~ -41 ℃
- Malo otentha: 135-137 ℃
-Kuchulukana: 1.05 g/mL
-Kusungunuka: Kusungunuka muzinthu zosungunulira za organic monga dimethylformamide, dichloromethane, methanol ndi ethanol.
Gwiritsani ntchito:
- 3, asidi pinacol ester ndi chimodzi mwa zofunika intermediates mu kaphatikizidwe organic. Itha kugwiritsidwa ntchito ngati reagent pomanga ma bondi a C-O ndi C-C, ndipo imagwiritsidwa ntchito ngati chothandizira kuti C-C ilumikizane monga Suzuki reaction ndi Stille reaction.
-Chigawocho chingagwiritsidwenso ntchito pokonzekera magulu ena ogwira ntchito kapena mankhwala, monga aldehydes, ketones ndi acids.
Njira:
- 3, asidi pinacol ester nthawi zambiri amakonzedwa pochita Pyran ndi pinacol ya boronic acid pansi pa alkali catalysis. Njira yeniyeni yokonzekera ikhoza kusankhidwa malinga ndi zofunikira zenizeni, ndipo njira yokonzekera yodziwika bwino imaphatikizapo kugwiritsa ntchito sodium borate ndi pinacol kuti achite pansi pa zinthu zamchere.
Zambiri Zachitetezo:
3, asidi pinacol ester akhoza kuvulaza thanzi ndi chilengedwe. Kugwiritsiridwa ntchito kuyenera kutsata ndondomeko zoyenera za labotale ndikukhala ndi zida zodzitetezera, monga magolovesi a labotale ndi chitetezo cha maso.
Kuphatikiza apo, zidziwitso zenizeni zachitetezo ndi malangizo ogwiritsira ntchito zikuyenera kuloza ku pepala lachitetezo chapagulu (SDS) kapena maumboni ena odalirika a mankhwala.
