Mawu Oyamba
3,5-Dichloropyridine ndi organic pawiri. Ndi madzi opanda mtundu okhala ndi fungo lamphamvu.
3,5-dichloropyridine imachitanso mosavuta ndi sodium hydroxide kupanga mpweya wapoizoni wa hydrogen chloride.
3,5-Dichloropyridine ili ndi ntchito zosiyanasiyana mu organic synthesis process. Itha kugwiritsidwa ntchito ngati chinthu chofunikira kwambiri chochepetsera pakupanga ma ketones.
Pali njira zingapo zopangira 3,5-dichloropyridine. Njira yodziwika bwino imapezeka pochita pyridine ndi mpweya wa chlorine. Masitepe enieni ndi awa: kukhazikitsidwa kwa mpweya wa chlorine mu yankho lomwe lili ndi pyridine pansi pamikhalidwe yoyenera. Zitachitika izi, mankhwala a 3,5-dichloropyridine adayeretsedwa ndi distillation.
Mukamagwiritsa ntchito 3,5-dichloropyridine, njira zoyendetsera chitetezo ziyenera kutsatiridwa ndikuvala zida zodzitetezera. Pewani kukhudza khungu, maso, ndi mucous nembanemba. Chisamaliro chiyenera kutengedwa kuti zisagwirizane ndi mankhwala ena panthawi yogwira ndi kusunga kuti zisawonongeke. Posungira, 3,5-dichloropyridine iyenera kusungidwa mu chidebe chopanda mpweya ndikuyikidwa pamalo ozizira, owuma.
