Selelekela
2-Cyano-3,5-dichloropyridine ke motsoako oa organic o nang le foromo ea lik'hemik'hale C6H2Cl2N2. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
2-Cyano-3,5-dichloropyridine ke 'mala o mosehla o mosehla kapa o se nang mebala. E na le volatility e tlase mocheso oa kamore. E na le ho qhibiliha ho fokolang metsing le ho qhibiliha ho holimo ho li-solvents tse kang ethanol le dimethylformamide.
Sebelisa:
2-Cyano-3,5-dichloropyridine e na le mefuta e mengata ea likopo ho organic synthesis. E ka sebelisoa e le setsi sa ho kopanya metsoako e fapaneng ea lintho tse phelang (tse kang lithethefatsi, dae le chefo e bolaeang likokoanyana). Ntle le moo, e ka sebelisoa hape e le lisebelisoa lipatlisisong tsa organic light-emitting diode (OLED) le lipontšo tsa kristale ea metsi.
Mokhoa oa ho itokisa:
2-Cyano-3,5-dichloropyridine e ka lokisoa ho sebelisoa mekhoa e fapaneng ea maiketsetso. Mokhoa o tloaelehileng oa maiketsetso ke ho itšoara ka motsoako oa pyridine o nang le cyanide, o lateloa ke chlorination ho fumana sehlahisoa.
Lintlha tsa Tšireletseho:
2-Cyano-3,5-dichloropyridine e ka nkoa e le kotsi tlas'a maemo a tloaelehileng. E ka 'na ea halefisa pampiri ea ho hema, mahlo le letlalo. Ha o sebelisoa, o lokela ho nka mehato e nepahetseng ea ts'ireletso, joalo ka ho roala liatlana le likhalase. Qoba ho kopana le li-oxidizing agents le li-acid tse matla nakong ea ho boloka le ho sebetsana. Haeba o pepesitsoe kapa o hema, batla thuso ea bongaka hang-hang.
