Isingeniso
I-2-nitro-4-fluorobenzoic acid iyinhlanganisela ephilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2-nitro-4-fluorobenzoic acid iyi-crystalline eqinile engenambala noma ephuzi.
- Ukunyibilika: kuncibilika kwezinye izinyibilikisi eziphilayo njenge-ethanol ne-methylene chloride, encibilika kancane emanzini.
Sebenzisa:
- I-2-Nitro-4-fluorobenzoic acid ivame ukusetshenziswa njengendawo ephakathi ekuhlanganiseni kwe-organic for synthesis yezinye izinhlanganisela.
Indlela:
- Ukulungiswa kwe-2-nitro-4-fluorobenzoic acid kuvame ukutholwa nge-nitrification. Enye indlela engenzeka iwukusabela i-2-bromo-4-fluorobenzoic acid ne-nitric acid. Ukusabela kudinga ukubhangqwa nezimo ezifanele zokusabela kanye nama-catalyst.
Ulwazi Lokuphepha:
- I-2-Nitro-4-fluorobenzoic acid iyinhlanganisela yemvelo enobuthi futhi ecasulayo. Ukuchayeka noma ukuhogela izingxube eziningi kungaba yingozi empilweni.
- Izinyathelo ezifanele zokuphepha kufanele zithathwe lapho uphatha, ugcina futhi uphatha, okuhlanganisa ukugqoka amagilavu okuzivikela kanye nezibuko.
- Gwema ukuthintana nama-oxidizing aqinile nezinto ezivuthayo ukuvikela umlilo noma ukuqhuma.
