Isingeniso
I-3-nitro-4-fluorobenzoic acid iyinhlanganisela ephilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza, nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Okuqinile okucwebezelayo okumhlophe.
- Ukuncibilika: akuncibiliki emanzini, kuncibilika kancane otshwaleni nama-ether.
Sebenzisa:
- I-3-Nitro-4-fluorobenzoic acid isetshenziswa kakhulu njengendawo ephakathi kokusabela kwe-organic synthesis.
Indlela:
I-3-nitro-4-fluorobenzoic acid ingatholwa ngokusabela esikhundleni se-p-nitrotoluene. Izinyathelo ezithile ezokuqala ukufaka esikhundleni se-fluorine esikhundleni se-nitrotoluene ngaphansi kwezimo ezine-asidi ukuze kutholwe i-3-nitro-4-fluorotoluene, bese kuba okunye ukusabela kwe-oxidation ukuze kutholwe i-3-nitro-4-fluorobenzoic acid.
Ulwazi Lokuphepha:
- I-3-nitro-4-fluorobenzoic acid ingaba yingozi kubantu, iyacasula emehlweni nasesikhumbeni.
- Uma usebenzisa, gwema ukuthintana ngqo nesikhumba namehlo, futhi usebenzise amagilavu okuzivikela kanye nezibuko uma kunesidingo.
- Ngesikhathi sokuyigcina, kufanele igcinwe endaweni emnyama, eyomile, nepholile, kude nomlilo nama-oxidants.
- Uma ulahla imfucuza, sicela uhambisane nemithetho efanele yokuphepha ukuze uvimbele ukungcoliswa kwemvelo.
