Isingeniso
I-4-Bromo-2-nitrobenzoic acid iyinhlanganisela yemvelo, evame ukufushaniswa njenge-BNBA. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-4-Bromo-2-nitrobenzoic acid iyikristale eqinile emhlophe.
- I-Solubility: Ingancibilika kahle kuzincibilikisi ezivamile ezifana ne-ethanol, i-chloroform ne-dimethylformamide.
Sebenzisa:
- Inkambu ye-Pigment: Le nhlanganisela ingasetshenziswa ukulungisa izingulube ezithile ezikhethekile.
Indlela:
- Ukulungiswa kwe-4-bromo-2-nitrobenzoic acid kuvame ukutholwa ngokuphendula i-2-nitrobenzoic acid ne-bromine ngaphansi kwezimo ezine-acidic. Ukuze uthole indlela eqondile yokulungiselela, sicela ubheke imibhalo efanele ye-organic synthesis.
Ulwazi Lokuphepha:
- I-compound inokucasuka okuthile, futhi izinyathelo zokuzivikela ezifana nokugqoka amagilavu, izibuko, njll, kufanele zithathwe ngesikhathi sokusebenza.
- Gwema amalangabi avulekile kanye nezinto ezishisa kakhulu, futhi ugcine endaweni epholile, eyomile.
- Kunedatha yobuthi enganele, ubuthi be-4-bromo-2-nitrobenzoic acid akwaziwa, futhi kufanele kuqashelwe uma usebenzisa noma uyiphatha, futhi izinqubo zokusebenza eziphephile ezifanele kufanele zilandelwe.
