Mawu Oyamba
5-Bromo-2-fluoropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
Maonekedwe: 5-bromo-2-fluoropyridine ndi yolimba yopanda mtundu mpaka yachikasu.
Kusungunuka: Imasungunuka mu zosungunulira za organic monga ethanol, dimethylformamide (DMF) ndi dichloromethane.
Gwiritsani ntchito:
Kaphatikizidwe ka mankhwala: 5-bromo-2-fluoropyridine angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic ndi mbali yofunika kwambiri yokonza zina organic mankhwala.
Njira:
Nthawi zambiri, njira yokonzekera 5-bromo-2-fluoropyridine imakhala ndi izi:
Pyridine imakhudzidwa ndi hydrogen fluoride kuti ipereke 2-fluoropyridine.
2-Fluoropyridine imayendetsedwa ndi bromine pansi pamikhalidwe yamchere kuti ipeze 5-bromo-2-fluoropyridine.
Zambiri Zachitetezo:
Chitetezo: 5-Bromo-2-fluoropyridine ikhoza kukhala yovulaza thanzi ndi chilengedwe, ndipo njira zoyendetsera chitetezo ziyenera kutsatiridwa. Kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupewedwa mukamagwiritsa ntchito, ndipo mpweya wabwino uyenera kutsimikizika.
Kusungirako: 5-Bromo-2-fluoropyridine iyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi moto ndi zinthu zoyaka.
Kutaya zinyalala: Malinga ndi malamulo amderalo, zinyalala za 5-bromo-2-fluoropyridine ziyenera kutayidwa moyenera malinga ndi malamulo oyenerera.
