Isingeniso
I-3-Nitro-5-bromobenzoic acid (3-Bromo-5-nitrobenzoic acid) iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C7H4BrNO4. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: I-3-Nitro-5-bromobenzoic acid iqinile eliphuzi elikhanyayo.
-Indawo yokuncibilika: cishe ku-220-225°C.
-Ukunyibilika: Ukuncibilika okuphansi emanzini, kodwa kuncibilika kuzincibilikisi ezifana ne-ethanol, i-chloroform ne-dichloromethane.
I-asidi ne-alkaline: i-asidi ebuthakathaka.
Sebenzisa:
-3-nitro-5-bromobenzoic acid ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis futhi isetshenziswa ekulungiseleleni ezinye izinhlanganisela.
-Ingasetshenziswa futhi ukulungisa izinhlanganisela ezifana nemithi, odayi kanye nama-coatings.
Indlela Yokulungiselela:
Ukulungiswa kwe-3-nitro-5-bromobenzoic acid kungaqedwa ngezinyathelo ezilandelayo:
1. I-3-nitrobenzoic acid itholwe ngokusabela kwe-benzoic acid ne-nitrous acid.
2. Uma kukhona i-ferrous bromide, i-3-nitrobenzoic acid isabela nge-sodium bromide ukuze ithole i-3-nitro-5-bromobenzoic acid.
Ulwazi Lokuphepha:
I-3-Nitro-5-bromobenzoic acid ngokuvamile iphephile uma isetshenziswa futhi igcinwa kahle. Nokho, lezi zindaba ezilandelayo zisadinga ukuqashelwa:
-Gwema ukuthintana kwesikhumba, ukuhogela umoya nokuwungenisa ngesikhathi usebenza.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezihlangu zobuso uma zisetshenziswa.
-Uma uhlangana nenhlanganisela, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-kufanele igcinwe kude nomlilo kanye ne-oxidant, endaweni epholile, eyomile.
Qaphela: Imininingwane engenhla ingeyereferensi kuphela. Sicela ulandele imithetho yokuphepha efanele lapho usebenza elabhorethri, futhi uthintane nephepha ledatha yezokuphepha lenhlanganisela ethile uma kunesidingo.
