2-Methyl-5-nitropyridine (CAS# 21203-68-9)
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
Isingeniso
I-2-methyll-5-nitropyridine iyinhlanganisela ye-organic enefomula yamakhemikhali i-C6H6N2O2, enalezi zinto ezilandelayo:
1. Ukubukeka: ikristalu engenambala kuya kophuzi okhanyayo;
2. Iphunga: alikho iphunga elikhethekile;
3. Iphuzu Elincibilikayo: 101-104 degrees Celsius;
4. Ukuncibilika: cishe akuncibiliki emanzini, kuncibilika kuzincibilikisi zemvelo njenge-ethanol ne-dichloromethane.
I-2-Methyl-5-nitropyridine isetshenziswa ngokuyinhloko njengento eluhlaza futhi ephakathi ku-organic synthesis kanye nemboni yezemithi. Ingasetshenziselwa ukuhlanganiswa kwe-pyridine ne-thiophene compounds, futhi ingasetshenziselwa ukulungiswa kwezibulala-zinambuzane, odayi kanye nezinye izinhlanganisela emkhakheni wezokwelapha.
Ukulungiswa kwe-2-methyll-5-nitropyridine kungenziwa ngezinyathelo ezilandelayo:
I-1.2-pyridine acetic acid ne-sodium nitrite zisabela ngaphansi kwezimo ezine-acidic ukukhiqiza i-2-nitropyridine.
2. Ukusabela kwe-2-Nitro pyridine nge-methylating reagent (njenge-methyl iodide) ukukhiqiza i-2-Methyl-5-nitropyridine.
Uma usebenzisa futhi ugcina i-2-methyll-5-nitropyridine, udinga ukunaka ulwazi olulandelayo lokuphepha:
-Kuyinto evuthayo, gwema ukuthintana nomlilo;
-Naka izinyathelo zokuzivikela ngesikhathi sokusebenza, njengokugqoka izibuko zokuzivikela namagilavu;
-gwema ukuhogela igesi noma uthuli, gwema ukuthintana kwesikhumba;
- Gcina esitsheni esivaliwe, kude nomlilo kanye nama-oxidizing agents;
-Gwema ukuxutshwa nama-oxidants aqinile noma ama-asidi aqinile.
