| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S22 - Ungaphefumuli uthuli. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |
| Ama-ID e-UN | UN 3459 |
Isingeniso
I-1-Bromo-4-nitrobenzene iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C6H4BrNO2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
I-1-Bromo-4-nitrobenzene iyikristalu eliphuzi eliphaphathekile elinokunambitheka kwe-alimondi okubabayo. Iqinile ekushiseni kwegumbi futhi inephuzu eliphezulu lokuncibilika nendawo yokubila. Ayincibiliki kahle emanzini, kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether.
Sebenzisa:
I-1-Bromo-4-nitrobenzene inohlu olubanzi lokusetshenziswa ku-organic synthesis. Ingasetshenziswa njengendawo ephakathi yokuhlanganiswa kwezinye izinhlanganisela eziphilayo, njengezidakamizwa, odayi nezibulala-zinambuzane. Ingasetshenziswa futhi njengento yokuqala ekuphenduleni kokwenziwa kwama-antibiotics, amahomoni nezimonyo.
Indlela Yokulungiselela:
Ukulungiswa kwe-1-Bromo-4-nitrobenzene kungenziwa ngezinyathelo ezilandelayo:
1. i-nitric acid ihlangana ne-bromobenzene ukwenza i-4-nitrobromobenzene.
2. I-4-nitrobromobenzene iguqulelwa ku-1-Bromo-4-nitrobenzene ngokusabela kokunciphisa.
Ulwazi Lokuphepha:
I-1-Bromo-4-nitrobenzene into eyingozi ecasulayo futhi eyenza umdlavuza. Gqoka amagilavu okuzivikela kanye nezibuko ukuze ugweme ukuthinta isikhumba namehlo. Gwema ukuhogela uthuli noma umhwamuko wayo futhi uqinisekise ukuthi isetshenziswa endaweni enomoya omuhle. Ekugcinweni nasekuphatheni, ukulandela izinqubo zokuphepha ezifanele.
