Mawu Oyamba
2-Methyl-4-bromopyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methyl-4-bromopyridine:
Ubwino:
- 2-Methyl-4-bromopyridine ndi yolimba yachikasu yopanda mtundu.
- 2-Methyl-4-bromopyridine ndi pafupifupi osasungunuka m'madzi koma sungunuka mu zosungunulira organic.
Gwiritsani ntchito:
- 2-Methyl-4-bromopyridine angagwiritsidwe ntchito ngati zopangira ndi reagent mu organic synthesis.
Njira:
- 2-Methyl-4-bromopyridine angapezeke pochita 2-methyl-4-pyridine methanol ndi phosphorous tribromide.
- Pa anachita, 2-methyl-4-pyridine methanol ndi phosphorous tribromide anawonjezera kuti anachita chotengera, zimene osakaniza anali usavutike mtima, ndiyeno 2-methyl-4-bromopyridine anali oyeretsedwa ndi distillation ndi njira zina.
Zambiri Zachitetezo:
- 2-Methyl-4-bromopyridine ingayambitse kupsa mtima kwa maso, khungu, ndi kupuma ndipo iyenera kupewedwa ikagwiritsidwa ntchito.
- Valani zodzitchinjiriza zamaso, magolovesi ndi chitetezo cha kupuma mukamagwiritsa ntchito.
- Ndi chinthu chapoizoni ndipo chiyenera kusungidwa bwino ndi kusungidwa kutali ndi magwero a moto ndi oxidizing agents.
- Ngati 2-methyl-4-bromopyridine ilowetsedwa kapena kulowetsedwa, pitani kuchipatala mwamsanga.
