4-Iodo-3-nitrobenzoic acid ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H4INO4. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
-Ponahalo: 4-Iodo-3-nitrobenzoic acid ke phofo e mosehla ea kristale.
- Sebaka sa ho qhibiliha: hoo e ka bang 230°C.
-Solubility: E qhibiliha ka har'a ethanol, ether le chloroform, ha e qhibilihe ka metsing.
Sebelisa:
- 4-Iodo-3-nitrobenzoic acid e sebelisoa haholo-holo e le karolo e bohareng ea motsoako oa manyolo.
-Ke thepa ea bohlokoa e tala bakeng sa motsoako oa lithethefatsi le chefo e bolaeang likokoanyana.
-E ka boela ea sebelisoa bakeng sa ho kopanya likarolo tse hlahisang leseli ho lisebelisoa tsa organic electroluminescent (OLED).
Mokhoa oa ho itokisa:
Ho na le mekhoa e mengata ea ho lokisa 4-Iodo-3-nitrobenzoic acid, e 'ngoe ea eona e atisang ho sebelisoa ho fumana ka nitration ea iodobenzoic acid. Mehato e khethehileng ea ho itokisa ke e latelang:
1. qhala iodobenzoic acid ka concentrated nitric acid.
2. Butle-butle eketsa concentrated sulfuric acid ka mocheso o tlase 'me u tsose karabelo.
3. Ka mor'a hore karabelo e etsoe ka nako e itseng, sehlahisoa sa tharollo ea karabelo se arohanngoa ke ho hloekisa kapa crystallization.
4. 4-Iodo-3-nitrobenzoic acid e ile ea qetella e hloekisitsoe ka ho hlatsoa ka solvent e loketseng le crystallization.
Lintlha tsa Tšireletseho:
- 4-Iodo-3-nitrobenzoic acid ke motsoako oa lintho tse phelang. Mehato ea tšireletso ea botho e lokela ho nkoa ha u e sebelisa, e kang ho roala liatlana le likhalase tse sireletsang mahlo.
-Motsoako o senya ho isa tekanyong e itseng, qoba ho kopana le letlalo le ho hema.
-Nakong ea ts'ebetso, ela hloko ho qoba ho kopana le li-oxidants tse matla le lisebelisoa tse fokotsang ho qoba liketso tse kotsi.
-Nakong ea polokelo, e lokela ho bolokoa sebakeng se pholileng, se omeletseng, se nang le moea o motle, se arohaneng le lintho tse tukang le tse tukang.
-Haeba ho kopana ho etsahala, hang-hang hlatsoa sebaka se amehileng ka metsi a mangata 'me u batle thuso ea bongaka.
