2-Bromo-4-methyl-3-nitropyridine (CAS# 23056-45-3)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso |
| I-Hazard Class | I-IRRITANT |
Isingeniso
Kuyinhlanganisela ye-organic enefomula yamakhemikhali ye-C, H, BrN, O. Okulandelayo yisingeniso sezinye izici zayo, ukusetshenziswa, izindlela kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Ayinambala ikristalu ephuzi noma ifomu lempushana.
-I-Solubility: Ingancibilika kuma-solvents ephilayo, njenge-ethanol, i-dimethyl sulfoxide ne-chloroform, kodwa ingancibiliki emanzini.
Sebenzisa:
-I-Synthetic chemistry: I-ligand evame ukusetshenziswa, engakha ama-complexes anezinsimbi eziguqukayo futhi isetshenziswe njengama-catalysts ku-organic synthesis.
-Ukukhiqiza izibulala-zinambuzane: Ingasetshenziswa futhi njengendawo emaphakathi yezibulala-zinambuzane ezithile.
Indlela:
Indlela yokulungiselela ingenziwa ngezinyathelo ezilandelayo:
1. Okokuqala, i-lutidine incibilika ku-dimethyl sulfoxide.
2. Emazingeni okushisa aphansi, kancane kancane engeza i-nitric acid ngenkathi ugcina izinga lokushisa lingaphansi kuka-0 degrees Celsius.
3. Faka kancane kancane i-bromoethane Dropwise ohlelweni lokusabela, qhubeka nokugcina izinga lokushisa eliphansi, futhi ugovuze kuze kube sekupheleni kokusabela.
4. Ekugcineni, ingxube yokusabela iyahlungwa, igezwe, icwecwe futhi yomiswe ukuze kutholwe i-calcium.
Ulwazi Lokuphepha:
Kungase kubangele izingozi ezithile emzimbeni womuntu kanye nemvelo, ngakho-ke udinga ukunaka izindaba zempilo nokuphepha lapho usebenzisa futhi uphatha. Nazi ezinye izinto ezicatshangelwayo zokuphepha:
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko nezimpahla zokuzivikela uma zisetshenziswa.
-Gwema ukuhogela uthuli lwayo kanye nokuthinta isikhumba. Uma kwenzeka ukuthintana ngephutha, shayela ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha.
- Gwema izindawo zokushisa nezomlilo ngesikhathi sokugcina nokuphatha, futhi ugcine umoya omuhle.
-Gwema ukuthintana ngqo nama-oxidants, ama-acids, ama-alkali nezinye izinto ukuze ugweme ukusabela okuyingozi.
Sicela uqaphele ukuthi imininingwane enikezwe lapha ingeyereferensi kuphela. Lapho usebenzisa futhi uphatha amakhemikhali ngokwenza, qiniseka ukuthi ubhekisela ezincwadini ezifanele kanye nemithetho yokuphatha yokuphepha, futhi ulandele isiqondiso sochwepheshe.
