Mawu Oyamba
2-Bromo-5-chloropyridine ndi organic pawiri, zotsatirazi ndi mawu oyamba ena katundu, ntchito, kukonzekera njira ndi chitetezo zambiri 2-bromo-5-chloropyridine:
Ubwino:
1. Maonekedwe: 2-bromo-5-chloropyridine ndi yopanda mtundu mpaka chikasu cholimba.
3. Kusungunuka: 2-bromo-5-chloropyridine ili ndi kusungunuka kwabwino muzosungunulira zamagulu, monga ethanol, acetone ndi dimethyl thionite ether.
Gwiritsani ntchito:
1. Mankhwala opangira mankhwala: 2-bromo-5-chloropyridine nthawi zambiri amagwiritsidwa ntchito ngati reagent mu kaphatikizidwe ka organic.
2. Mankhwala ophera tizilombo: Amagwiritsidwanso ntchito popanga mankhwala ophera tizilombo ngati zinthu zopangira mankhwala ophera tizilombo kapena ophera udzu.
Njira:
The yokonza 2-bromo-5-chloropyridine akhoza analandira ndi zimene 2-chloropyridine ndi hydrobromic acid. Masitepe enieni monga Kutha 2-chloropyridine mu anhydrous cyclohexane, kuwonjezera hydrobromic acid, Kutenthetsa anachita ndi yogwira mtima, pambuyo zimene anamaliza, chifukwa organic gawo amalekanitsidwa ndi madzi ndi ano zimalimbikitsa sodium kolorayidi njira, ndi chandamale mankhwala amayeretsedwa ndi kuyanika. mankhwala ndi distillation.
Zambiri Zachitetezo:
1. 2-Bromo-5-chloropyridine ali ndi zotsatira za carcinogenic ndi kawopsedwe ku ubereki, ndipo kusamala kuyenera kutengedwa panthawi yogwiritsira ntchito.
2. Pewani kukhudza khungu ndi maso.
3. Pogwiritsira ntchito ndi kusunga, ziyenera kukhala kutali ndi moto ndi gwero la kutentha.
4. Mpweya wabwino wa mpweya uyenera kusungidwa panthawi yogwira ntchito.
5. Chonde tsatirani mosamalitsa njira zotetezera ndikugwiritsa ntchito zida zodzitetezera.
