Selelekela
2-Chloro-4-methyl-3-nitropyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Thepa: 2-Chloro-4-methyl-3-nitropyridine ha e na 'mala ho isa ho bosehla bo khanyang bo tiileng le monko o monate. Ha e qhibilihe ka metsing 'me e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide. E chefo haholo.
Tšebeliso: 2-chloro-4-methyl-3-nitropyridine e sebelisoa haholo-holo e le lisebelisoa tsa bohlokoa tse mahareng le tsa maiketsetso ho motsoako oa manyolo. E ka boela ea sebelisoa ha ho etsoa li-complexes tsa tšepe le li-catalysts.
Mokhoa oa ho itokisa: Ho lokisoa ha 2-chloro-4-methyl-3-nitropyridine hangata ho qala ka 2-chloro-4-methylpyridine. Ntlha ea pele, 2-chloro-4-methylpyridine e ile ea arabela ka acid e concentrated nitric, 'me joale sehlahisoa se ne se hloekisoa le ho hloekisoa ho fumana 2-chloro-4-methyl-3-nitropyridine.
Tlhahisoleseding ka Polokeho: 2-Chloro-4-methyl-3-nitropyridine ke ntho e chefo e ka bakang kotsi ho bophelo bo botle ha e ka pepesetsoa mouoane oa eona, phofshoana, kapa methapong ea eona. Hoa teneha ebile hoa utloahala 'me ho lokela ho qojoa ho kopana le letlalo, mahlo, le tsela ea ho hema. Mehato e nepahetseng ea tšireletso e lokela ho nkoa ha u tšoara kapa u boloka, joalo ka ho roala thepa e loketseng ea ho itšireletsa (mohlala, liatlana, likhalase le limaske). Ha o sebelisoa, etsa bonnete ba hore ho na le tikoloho e nang le moea o motle 'me u qobe ho kopana le lintho tse tukang. Litšila leha e le life tse amanang le 2-chloro-4-methyl-3-nitropyridine li lokela ho lahloa ho latela melao ea lehae. Ha o sebelisa kapa o sebetsana le motsoako ona, mekhoa e nepahetseng ea ts'ebetso ea ts'ireletso le litataiso li lokela ho lateloa ka thata.
