3-BROMO-2-CHLORO-5-NITRO-6-PICOLINE (CAS# 856834-95-2) mawu oyamba

3-Bromo-2-chloro-6-methyl-5-nitropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:

Ubwino:
- Maonekedwe: 3-Bromo-2-chloro-6-methyl-5-nitropyridine ndi ufa woyera wonyezimira wachikasu.
- Kusungunuka: Imasungunuka bwino mu zosungunulira za organic monga ethanol, dimethylformamide ndi chloroform, koma imasungunuka pang'ono m'madzi.

Gwiritsani ntchito:
- Mankhwala ophera tizirombo: Atha kugwiritsidwanso ntchito ngati zopangira kapena zopatsirana popanga mankhwala ophera tizilombo ndi fungicides.

Njira:
Kukonzekera kwa 3-bromo-2-chloro-6-methyl-5-nitropyridine kumatha kuchitika ndi izi:
2-methyl-3-nitropyridine imasungunuka mu ethanol ndipo owonjezera sulfuric acid amawonjezedwa kuti athandize zomwe zikuchitika.
Zomwe zimasakanikirana zidakhazikika ndikuthandizidwa ndi thionyl chloride ndi magnesium bromide.
Zomwe osakaniza amachepetsedwa, ndiyeno mankhwalawa amayeretsedwa ndi evaporation ndi crystallization.
Kupyolera mu kusefera, kuyanika ndi pulverization, chomaliza cha 3-bromo-2-chloro-6-methyl-5-nitropyridine chimapezeka.

Zambiri Zachitetezo:
- 3-Bromo-2-chloro-6-methyl-5-nitropyridine ndi cholimba choyaka moto ndipo chimapewa kukhudzana ndi zoyatsira.
- Pogwira ntchito, mpweya wabwino uyenera kugwiritsidwa ntchito komanso zida zodzitetezera monga magolovesi ndi magalasi achitetezo ayenera kugwiritsidwa ntchito.
- Pewani kutulutsa fumbi kapena kukhudzana ndi khungu ndi maso, ndipo pewani kuloŵa mwangozi.
- Chonde sungani bwino, kutali ndi moto ndi zinthu zoyaka, komanso kutali ndi ana ndi nyama.
