Kenyelletso e khutšoanyane
3-Bromo-5-nitro-2-hydroxypyridine ke motsoako oa organic o atisang ho khutsufatsoa joalo ka BNHO.
Thepa: Ponahalo:
- Ponahalo: BNHO ke kristale e 'mala o mosehla o bobebe kapa phofo ea kristale.
- Sollubility: e qhibiliha hanyane ka metsing, e qhibiliha ka joala, ether le lihlapolli tse ling tsa tlhaho.
Lisebelisoa:
- Lintho tse tala tse bolaeang likokoanyana: BNHO e ka sebelisoa e le lisebelisoa tse tala bakeng sa ho kopanya chefo e itseng.
Mokhoa oa ho itokisa:
Ho na le mekhoa e 'meli e tloaelehileng ea ho itokisa: e 'ngoe ke ka alkylation reaction ea bromobenzene le 2-hydroxypyridine ho fumana 3-bromo-2-hydroxypyridine, ebe e arabela ka nitric acid ho fumana 3-bromo-5-nitro-2-hydroxypyridine. E 'ngoe ke ka karabelo ea 2-bromo-3-methylpyridine e nang le nitric acid ho fumana 3-bromo-5-nitro-2-hydroxypyridine.
Lintlha tsa Tšireletseho:
- BNHO ke motsoako oa organohalogen o chefo le o halefisang le mehato ea tšireletso e lokelang ho hlokomeloa.
- Qoba ho kopana le letlalo, mahlo le lera la mucous; ha e ka kopana, e hlatsoe hang-hang ka metsi a mangata.
- Apara lisebelisoa tse loketseng tsa ho itšireletsa, joalo ka liatlana tsa laboratori le likhalase tsa tšireletso, ha u li sebelisa le ho li lokisa.
- Qoba ho hema mouoane kapa lerōle la eona le ho sebetsa sebakeng se nang le moea o motle.
- E lokela ho bolokoa sebakeng se omeletseng, se phodileng le se nang le moea o pholileng hole le mehloli e tukang kapa lintho tse etsang oxidizing.
