Nhanganyaya
2-Methyl-4-bromopyridine is organic compound. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-methyl-4-bromopyridine:
Hunhu:
- 2-Methyl-4-bromopyridine haina ruvara kune yakachenuruka yero yakasimba.
- 2-Methyl-4-bromopyridine inenge isinganyungudike mumvura asi inonyungudika muorganic solvents.
Shandisa:
- 2-Methyl-4-bromopyridine inogona kushandiswa seyakasvibiswa uye reagent mune organic synthesis.
Nzira:
- 2-Methyl-4-bromopyridine inogona kuwanikwa nekuita 2-methyl-4-pyridine methanol ne phosphorus tribromide.
- Panguva yekupindura, 2-methyl-4-pyridine methanol uye phosphorus tribromide yakawedzerwa kumudziyo wekuita, musanganiswa wekuita wakapisa, uye ipapo 2-methyl-4-bromopyridine yakacheneswa ne distillation nedzimwe nzira.
Zvekuchengetedza
- 2-Methyl-4-bromopyridine inogona kukonzera kutsamwa kwemaziso, ganda, uye nzira yekufema uye inofanira kudziviswa kana yakashandiswa.
- Pfeka maziso ekudzivirira, magurovhosi uye dziviriro yekufema paunenge uchishandisa.
- Icho chinhu chine muchetura uye chinofanirwa kuchengetwa nemazvo uye kuchengetwa kure nenzvimbo dzemoto uye oxidizing agents.
- Kana 2-methyl-4-bromopyridine yakafemerwa kana kuiswa, tsvaga kurapwa nekukurumidza.
