Nhanganyaya
2-Bromo-5-nitropyridine isanganiswa ine organic formula C5H3BrN2O2. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
2-Bromo-5-nitropyridine ivhu chena rine kakunaka oxalic acid. Iine high thermal uye kugadzikana kwemakemikari. Inonyungudika zvishoma mumvura pane tembiricha yekamuri, inonyungudika muorganic solvents senge ethanol uye acetone.
Shandisa:
2-Bromo-5-nitropyridine ine huwandu hwakawanda hwekushandisa. Icho chakakosha mbishi zvinhu uye zvepakati mune organic synthesis. Inogona kushandiswa mukugadzirwa kwemishonga yezvipembenene, dhayi, photosensitive zvinhu uye mishonga yemishonga. Mukuwedzera, inogonawo kushandiswa sechinhu chinokonzera uye ligand.
Kugadzirira nzira:
2-Bromo-5-nitropyridine synthesis nzira dzinonyanya dzinotevera:
1. by 2-bromopyridine uye nitric acid reaction pasi pemamiriro ane acidic.
2. ne 3-bromopyridine uye sodium nitrite reaction pasi pemamiriro e-alkaline.
Zvekuchengetedza
2-Bromo-5-nitropyridine musanganiswa une muchetura une dzimwe njodzi. Teerera kune anotevera ekuchengetedza ekuchengetedza panguva yekushandiswa uye kuchengetedza:
1. kudzivirira inhalation yeguruva kana mhute, inofanira kunge iri munzvimbo ine mhepo inofefetera kuti ishande.
2. kudzivisa kusangana neganda, maziso uye mucous membranes, zvakadai sekubata kunofanira pakarepo kushambidza nemvura yakawanda, uye kutsvaga rubatsiro rwechiremba.
3. teerera kumoto uye kuputika matanho ekudzivirira, kudzivisa kusangana nezvinhu zvinopisa.
4. Chengetedza mumudziyo wakavharwa, kure nemoto uye oxidant.
5. Rasa maererano nemitemo yemunharaunda kuti udzivise kubuda kwakananga kune zvakatipoteredza.
Pfupiso:
2-Bromo-5-nitropyridine is organic compound ine zvakasiyana-siyana zvekushandisa. Nekudaro, nekuda kwehupfu hwayo, zvinofanirwa kutarisisa kushanda kwakachengeteka, kuchengetedza kwakaringana uye kuraswa kwezvinhu zvakasara.
