Mawu Oyamba
2-Bromo-5-(trifluoromethyl)pyridine (yomwe imadziwikanso kuti BTFP) ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Cholimba choyera
- Kulemera kwa maselo: 206.00 g / mol
- Kusungunuka: BTFP imasungunuka mosavuta mu zosungunulira za organic (mwachitsanzo, ma alcohols, ethers, ketoni) koma osasungunuka m'madzi.
Gwiritsani ntchito:
- Monga kaphatikizidwe wapakatikati: BTFP imagwiritsidwa ntchito kwambiri pokonzekera ma organic synthesis intermediates, monga mankhwala a pyridine, mankhwala onunkhira, etc.
- Monga ligand: BTFP ikhoza kugwiritsidwa ntchito ngati ligand yazitsulo zazitsulo ndipo imakhudzidwa ndi zochitika zosiyanasiyana zothandizira komanso kukonza zipangizo zogwirira ntchito.
- Monga reagent: BTFP imatenga gawo lofunikira pakuphatikizika kwachilengedwe, monga kuphatikizira kachitidwe, kachitidwe ka m'malo, komanso kuchepetsa kachitidwe.
Njira:
2-Bromo-5-(trifluoromethyl)pyridine ikhoza kupangidwa ndi njira zotsatirazi:
1. Sungunulani 2-amino-5- (trifluoromethyl) pyridine muzosungunulira zoyenera, monga mowa kapena ketone.
2. Onjezani mankhwala a bromini (monga hydrogen bromidi, methyl bromide).
3. Chitani zomwezo pa kutentha koyenera ndi kugwedeza zinthu.
4. Sefa mankhwala ndi kuchita crystallization ndi kuyeretsa.
Zambiri Zachitetezo:
- BTFP imatha kulimba kapena kuwunikira kutentha pang'ono, chonde sungani kutentha ndikupewa crystallization.
- Valani magolovesi oteteza komanso magalasi oyenera mukamagwira ntchito kuti musakhudze khungu ndi maso.
- Pewani kutulutsa fumbi kapena nthunzi yake, chifukwa BTFP ikhoza kukhala ndi zotsatira zokwiyitsa panjira yopuma.
- Onani buku loyenera lachitetezo mukamagwiritsa ntchito kapena pogwira BTFP, ndikutaya zinyalala ndi zosungunulira moyenera.
