Selelekela
Ke motsoako oa lintho tse phelang. E na le mokhoa oa lik'hemik'hale oa C5H3BrN4O2 le boima ba molek'hule ba 213.01g / mol. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:
Tlhaho:
-Ponahalo: Ke kristale e mosehla ho ea ho lamunu kapa phofo;
-Ntho ea ho qhibiliha: hoo e ka bang likhato tse 117-120 tsa Celsius;
-Solubility: E qhibiliha hanyenyane metsing 'me e qhibiliha ka har'a metsoako e meng ea tlhaho e kang joala, ester le ketone.
Sebelisa:
-Lithethefatsi synthesis: Hangata e sebelisoa e le setsi sa ka hare ho organic synthesis 'me e ka sebelisoa ho synthesize mefuta e fapaneng ya lithethefatsi, dae, chefo e bolaeang likokoanyana le metsoako e meng.
Mokhoa oa ho itokisa:
Ho na le mekhoa e mengata ea ho itokisa, 'me e latelang ke e' ngoe ea eona:
1. Ntlha ea pele, 3-bromo-5-nitropyridine e itšoara ka ammonia ho fumana 3-nitro-5-aminopyridine.
2. Sephetho sa 3-nitro-5-aminopyridine se sebetsa ka bromoalkane kapa acetyl ho fumana sehlahisoa sa ho qetela.
Lintlha tsa Tšireletseho:
Ka kakaretso e bolokehile ha e sebelisoa le ho bolokoa ka nepo. Leha ho le joalo, mehato e latelang ea ho itšireletsa e lokela ho nkoa:
-Apara lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana, likhalase le lijase tsa lab;
- Qoba ho ama letlalo, molomo le mahlo. Haeba ho na le ho kopana, hlatsoa hang-hang ka metsi a mangata;
- Sebelisa le ho boloka motsoako sebakeng se nang le moea o motle ho qoba ho hema khase kapa lerōle;
-U se ke ua boloka kapa ua sebelisa motsoako ka lintho tse tukang;
- Bala ka hloko, 'me u latele melao e nepahetseng ea ts'ireletso le taolo ea litšila pele e sebelisoa kapa e lahloa.
Ka kopo hlokomela hore lintlha tse fanoeng ka holimo ke tsa ho bua feela, 'me boemo bo itseng bo hloka ho utloisisoa le ho tiisoa ho latela litlhoko tsa sebele.
