Mawu Oyamba
2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) ndi organic pawiri ndi mankhwala formula C6H5Br2N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
2,3-dibromo-5-methylpyridine ndi yolimba yachikasu yokhala ndi fungo loipa. Ili ndi malo osungunuka pafupifupi madigiri 63-65 Celsius ndi malo owira pafupifupi 269-271 digiri Celsius. Izo sizisungunuka m'madzi ndipo zimasungunuka mu zosungunulira za organic.
Gwiritsani ntchito:
2,3-dibromo-5-methylpyridine ndi yosunthika organic synthesis yapakatikati. Angagwiritsidwe ntchito liphatikize ena organic mankhwala, monga zotumphukira za biologically yogwira zinthu, mankhwala ndi mankhwala. Itha kugwiritsidwanso ntchito popanga zida zamagetsi monga organic light-emitting diode (OLED) ndi mabatire achilengedwe.
Njira:
2,3-dibromo-5-methylpyrridine ingapezeke pochita 5-methylpyridine ndi bromine. 5-Methylpyridine imayamba kuchitapo kanthu ndi hydrogen bromide, kenako imapitilira kuchitapo kanthu ndi methyl chloride pamaso pa chothandizira kupanga chinthu chomwe mukufuna.
Zambiri Zachitetezo:
2,3-dibromo-5-methylpyrridine imakwiyitsa ndipo ingayambitse kupsa mtima kwa maso, khungu ndi kupuma. Pogwiritsa ntchito, njira zogwirira ntchito zotetezeka ziyenera kuwonedwa mosamalitsa, kukhudzana mwachindunji ndi khungu ndi maso kuyenera kupewedwa, ndipo ntchitoyo iyenera kutsimikiziridwa pamalo abwino mpweya wabwino. Pogwira ndi kusunga, chisamaliro chiyenera kutengedwa kuti zisagwirizane ndi zowonjezera zowonjezera ndi zinthu zoyaka moto kuti ziteteze kuopsa kwa moto ndi kuphulika. Ngati mutakoka mpweya kapena kukhudzana ndi mankhwalawa, funsani malangizo achipatala mwamsanga ndipo funsani dokotala.
