3-BROMO-2-CHLORO-5-NITRO-6-PICOLINE (CAS# 856834-95-2) selelekela

3-Bromo-2-chloro-6-methyl-5-nitropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

Boleng:
- Ponahalo: 3-Bromo-2-chloro-6-methyl-5-nitropyridine ke phofo e tiileng e tšoeu ho ea mosehla.
- Sollubility: E na le ho qhibiliha hamonate ho lihlapolli tsa tlhaho tse kang ethanol, dimethylformamide le chloroform, empa e na le metsi a fokolang haholo.

Sebelisa:
- Likokoana-hloko: E ka boela ea sebelisoa e le lisebelisoa tse tala kapa li-intermediate bakeng sa chefo e bolaeang likokoanyana ho lokiseng chefo e bolaeang likokoanyana le fungicides.

Mokhoa:
Tokisetso ea 3-bromo-2-chloro-6-methyl-5-nitropyridine e ka etsoa ka mehato e latelang:
2-methyl-3-nitropyridine e qhibiliha ka har'a ethanol mme acid e feteletseng ea sulfuric e eketsoa ho susumetsa karabelo.
Motsoako oa karabelo o ile oa pholile 'me oa phekoloa ka thionyl chloride le magnesium bromide.
Motsoako oa karabelo o hlapolotsoe, ebe sehlahisoa se hloekisoa ka mouoane le crystallization.
Ka ho hloekisa, ho omisa le ho phunya, sehlahisoa sa ho qetela sa 3-bromo-2-chloro-6-methyl-5-nitropyridine se fumanoa.

Lintlha tsa Tšireletseho:
- 3-Bromo-2-chloro-6-methyl-5-nitropyridine ke ntho e tiileng e tukang 'me e qoba ho kopana le mehloli ea mollo.
- Ho lokela hore ho sebelisoe moea o motle nakong ea ha ho sebetsoa, ​​'me ho sebelisoe lisebelisoa tsa ts'ireletso tse kang liatlana le likhalase.
- Qoba ho hema lerōle kapa ho kopana le letlalo le mahlo, 'me u qobe ho ja ka tšohanyetso.
- Ka kopo boloka ka nepo, hole le mollo le lintho tse tukang, le hole le bana le liphoofolo.
