Nhanganyaya
2-methyll-5-nitropyridine isanganiswa ine organic formula C6H6N2O2, ine zvinotevera:
1. Kuonekwa: kusina ruvara kune chiedza chekristaro cheyero;
2. Kunhuwa: hapana kunhuhwirira kunokosha;
3. Melting Point: 101-104 degrees Celsius;
4. Solubility: inenge isingasviki mumvura, inonyunguduka mu organic solvents yakadai se ethanol uye dichloromethane.
2-Methyl-5-nitropyridine inonyanya kushandiswa sechinhu chakasvibiswa uye chepakati mune organic synthesis uye indasitiri yemishonga. Inogona kushandiswa pakugadzirwa kwepyridine uye thiophene mishonga, uye inogonawo kushandiswa pakugadzira mishonga yezvipembenene, dhayi uye mamwe masanganiswa mumunda wemishonga.
Kugadzirira kwe2-methyll-5-nitropyridine kunogona kuitwa nematanho anotevera:
1.2-pyridine acetic acid uye sodium nitrite inoitwa pasi pemamiriro ane acidic kugadzira 2-nitropyridine.
2. Kuita kwe2-Nitro pyridine ine methylating reagent (yakadai semethyl iodide) kugadzira 2-Methyl-5-nitropyridine.
Paunenge uchishandisa uye kuchengeta 2-methyll-5-nitropyridine, unofanirwa kuterera kune inotevera chengetedzo ruzivo:
-Icho chinopisa, dzivisa kusangana nemoto;
-Kuteerera matanho ekudzivirira panguva yekushanda, sekupfeka magirazi ekudzivirira uye magurovhosi;
-dzivisa kufema kwegasi kana guruva, dzivisa kubata kweganda;
-Chengetedza mumudziyo wakavharwa, kure nemoto uye oxidizing agents;
-Dzivisa kusanganiswa nemaoxidants akasimba kana maasidhi akasimba.
