Selelekela
2,5-Dichloro-3-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: 2,5-Dichloro-3-nitropyridine ke kristale e se nang 'mala ho ea mosehla o mosehla.
- Sollubility: E qhibiliha ka har'a metsoako ea tlhaho e kang ethanol, dimethyl ether le chloroform, empa ha e qhibilihe ka metsing.
- Botsitso: Motsoako o tsitsitse mocheso oa kamore, empa o phatloha ka mocheso o phahameng kapa o kopana le li-oxidizing tse matla.
Sebelisa:
- Meriana e bolaeang likokoanyana: E ka sebelisoa e le sebolaea-kokoanyana 'me e na le phello e ntle ea taolo ho tse ling tse senyang lijalo.
Mokhoa:
Mokhoa oa ho kopanya oa 2,5-dichloro-3-nitropyridine hangata o kenyelletsa karabelo ea nitrification le karabelo ea chlorination. Har'a tsona, mokhoa o tloaelehileng oa ho kopanya ke ho nitrate 2,5-dichloropyridine e nang le nitric acid ka pel'a sulfuric acid. Mokhoa o mong ke ho itšoara ka 2-nitro-5-chloropyridine ka bromide ea koporo e acidic ho hlahisa 2,5-dichloro-3-nitropyridine.
Lintlha tsa Tšireletseho:
- 2,5-Dichloro-3-nitropyridine ke motsoako oa manyolo o hlokang ho sebetsoa ka hloko ho o thibela ho kopana le letlalo, mahlo le tsamaiso ea ho hema.
- Apara lisebelisoa tse nepahetseng tsa ts'ireletso, ho kenyeletsoa liaparo tse sireletsang mahlo, liatlana le lithebe tsa sefahleho, ha u sebetsa.
- Nakong ea ts'ebetso, qoba ho hema likhase, moholi kapa mouoane 'me u boloke moea o motle.
- Tabeng ea ho kopana le letlalo kapa mahlo, hlatsoa hang-hang ka metsi a mangata 'me u buisane le ngaka.
- Ha e bolokoa, 2,5-dichloro-3-nitropyridine e lokela ho bolokoa sebakeng se omeletseng, se phodileng, se nang le moea o pholileng, hole le ho khantša le li-oxidants.
