Mawu Oyamba
2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) ndi organic pawiri ndi mankhwala formula C5H3FN2O2. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: 2-Fluoro-5-nitropyridine ndi yoyera mpaka yotumbululuka yachikasu.
-Kusungunuka: Ikhoza kusungunuka muzitsulo zambiri za organic, monga ethanol, dimethylformamide ndi dichloromethane.
- Malo osungunuka: Malo ake osungunuka ndi pafupifupi 78-81 digiri Celsius.
Gwiritsani ntchito:
- 2-Fluoro-5-nitropyridine ndi othandiza organic synthesis wapakatikati, amene ali ndi ntchito zofunika popanga mankhwala ndi mankhwala.
- Itha kugwiritsidwa ntchito popanga mitundu yosiyanasiyana yamagulu achilengedwe, monga mankhwala, utoto ndi zokutira.
Njira Yokonzekera:
- 2-Fluoro-5-nitropyridine nthawi zambiri imakonzedwa ndi fluorination ndi nitration ya pyridine.
-Njira yeniyeni yokonzekera ingakhale ikuchita pyridine ndi hydrogen fluoride kapena ammonium fluoride kuti ipeze 2-fluoropyridine. 2-fluoropyridine imapangidwa ndi nitric acid kuti ipereke 2-Fluoro-5-nitropyridine.
Zambiri Zachitetezo:
- 2-Fluoro-5-nitropyridine ndi organic pawiri ndi mlingo wina wa ngozi. Pogwira ntchito, ndikofunikira kutsatira malamulo oyendetsera chitetezo.
-Zingakhale zokwiyitsa pakhungu ndi m'maso, motero njira zodzitetezera zikakhala zowonekera, monga kuvala magalasi oteteza ndi magalasi.
-Ngati walowetsedwa mwangozi kapena kukomoka, pitani kuchipatala ndikupatseni njira zoyenera zothandizira.
-Pa nthawi yosungirako, 2-Fluoro-5-nitropyridine iyenera kusungidwa pamalo ouma, ozizira, kutali ndi moto ndi oxidizing agents.
