2,3-Dibromopyridine (CAS # 13534-89-9) chiyambi

2,3-dibromopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira, ndi chidziwitso cha chitetezo:
chilengedwe:
-2,3-dibromopyridine ndi cholimba chachikasu mpaka chotumbululuka chokhala ndi fungo loyipa.
-Imasungunuka mu zosungunulira za organic monga ethanol, dimethylformamide, ndi dichloromethane kutentha kwa chipinda, koma osasungunuka m'madzi.
-Chigawochi chimatha kumva kuwala ndi mpweya ndipo chimayenera kusungidwa m'chidebe chomata kutali ndi kuwala.
Cholinga:
-2,3-dibromopyridine amagwiritsidwa ntchito ngati chinthu chofunikira kwambiri pakupanga organic.
- Itha kugwiritsidwa ntchito m'malo ndikusintha kwa condensation mu kaphatikizidwe ka organic.
Njira yopanga:
-Njira mwachizolowezi pokonzekera 2,3-dibromopyridine ndi bromination anachita pyridine.
-Njira yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri ndikuwotcha pyridine mumadzi okhazikika a bromine kuti achite, ndipo 2,3-dibromopyridine imachokera ku yankho lomwe limatha kuzirala.
Zambiri zachitetezo:
-2,3-dibromopyridine ndi mankhwala omwe amachititsa kuti maso ndi khungu likhale lopweteka pokhudzana.
- Zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera ziyenera kuvalidwa panthawi yogwira ntchito.
-Pewani kulowetsa fumbi kapena mpweya wake, ndikugwirira ntchito pamalo olowera mpweya wabwino.
