3-Nitro-5-bromobenzoic acid (3-Bromo-5-nitrobenzoic acid) ke motsoako oa organic o nang le foromo ea lik'hemik'hale C7H4BrNO4. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:
Tlhaho:
-Ponahalo: 3-Nitro-5-bromobenzoic acid ke 'mala o mosehla o khanyang.
- Sebaka sa ho qhibiliha: hoo e ka bang 220-225 ° C.
-Solubility: Ho qhibiliha ho tlaase metsing, empa ho qhibiliha ka har'a metsoako e kang ethanol, chloroform le dichloromethane.
-acid le alkaline: ke asiti e fokolang.
Sebelisa:
-3-nitro-5-bromobenzoic acid e atisa ho sebelisoa e le karolo e bohareng ea motsoako oa lintho tse phelang 'me e sebelisoa ho lokisetsa metsoako e meng.
-E ka boela ea sebelisoa ho lokisa metsoako e kang meriana, dae le litlolo.
Mokhoa oa ho itokisa:
Tokisetso ea 3-nitro-5-bromobenzoic acid e ka phethoa ka mehato e latelang:
1. Asiti ea 3-nitrobenzoic e fumanoe ka karabelo ea asiti ea benzoic le asiti ea nitrous.
2. Ka pel'a bromide ea ferrous, 3-nitrobenzoic acid e itšoara ka sodium bromide ho fumana 3-nitro-5-bromobenzoic acid.
Lintlha tsa Tšireletseho:
3-Nitro-5-bromobenzoic acid hangata e bolokehile tšebelisong e nepahetseng le polokelong. Leha ho le joalo, lintlha tse latelang li ntse li lokela ho hlokomeloa:
- Qoba ho kopana le letlalo, ho hema le ho kenya letsoho nakong ea ts'ebetso.
-Apara lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana, likhalase le lithebe tsa sefahleho ha u sebelisoa.
-Haeba u kopana le motsoako, hlatsoa hang-hang ka metsi a mangata 'me u batle ngaka.
-e lokela ho bolokoa hole le mollo le oxidant, sebakeng se phodileng, se omileng.
Tlhokomeliso: Lintlha tse ka holimo ke tsa litšupiso feela. Ka kopo latela melao e amehang ea polokeho ha u sebetsa ka laboratoring, 'me u shebe leqephe la polokeho ea komporo e itseng ha ho hlokahala.
