Mawu Oyamba
2-Chloro-6-methyl-5-nitropyridine ndi wamba organic pawiri,
Ubwino:
- Maonekedwe: 2-chloro-6-methyl-5-nitropyridine ndi kristalo wopanda mtundu kapena wachikasu.
- Kusungunuka: Imasungunuka mosavuta mu zosungunulira za organic monga ethanol, dimethylformamide ndi chloroform.
Gwiritsani ntchito:
- Utoto: Gululi litha kugwiritsidwa ntchito kupanga utoto wina wamafakitale, monga momwe kapangidwe kake kamakhala ndi mphamvu yotengera kuwala kwa UV, ndipo amagwiritsidwa ntchito kwambiri pamakampani opanga utoto ndi utoto.
Njira:
2-Chloro-6-methyl-5-nitropyridine angapezeke mwa chlorination ndi nitrification wa pyridine. Njira yeniyeni yokonzekera ingakhale kugwiritsa ntchito asidi wa nitric ndi sulfuric acid kuti apeze nitrite acid, amachitira nitrite ndi mkuwa nitrate kupanga mkuwa wa nitrate, ndiyeno kugwiritsa ntchito electrophilic methylation reagents (monga methyl halogen) kuti agwirizane ndi mkuwa nitrate kuti apeze chandamale mankhwala.
Zambiri Zachitetezo:
2-Chloro-6-methyl-5-nitropyridine ndi mankhwala oopsa omwe amakwiyitsa komanso owopsa. Mukamagwiritsa ntchito ndikugwira, muyenera kusamala zoyenera monga kuvala zovala zoteteza maso, magolovesi ndi zovala zodzitetezera. Pewani kutulutsa nthunzi kapena fumbi lake, ndipo pewani kukhudza khungu ndi maso. Mukamagwiritsa ntchito mankhwalawa, chisamaliro chiyenera kutengedwa kuti chikhale chokhazikika komanso kuti musagwirizane ndi mankhwala ena osagwirizana. Mukasunga, ziyenera kusungidwa mu chidebe chopanda mpweya, kutali ndi kuyatsa ndi okosijeni.
