Selelekela
3-bromo-4-methoxypyridine ke motsoako oa manyolo o nang le motsoako oa lik'hemik'hale oa C6H6BrNO le boima ba molek'hule oa 188.03. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
1. Ponahalo: 3-bromo-4-methoxypyridine ke 'mala o mosehla o mosehla ho ea ho o mosehla.
2. ho qhibiliha: ho qhibiliha ka har'a metsoako ea tlhaho e kang ether le hydrocarbons e chlorine, e sa qhibiliheng metsing.
3. sebaka se qhibilihang: hoo e ka bang 50-53 ℃.
4. boima ba 'mele: hoo e ka bang 1.54 g / cm.
Sebelisa:
3-bromo-4-methoxypyridine ke motsoako oa bohlokoa oa organic synthesis, o atisang ho sebelisoa ha ho etsoa chefo e bolaeang likokoanyana, meriana le metsoako e meng ea tlhaho. E na le mefuta e mengata ea likopo lefapheng la lipatlisiso tsa lik'hemik'hale le meriana.
Mokhoa oa ho itokisa:
3-bromo-4-methoxypyridine hangata e entsoe ka mehato e latelang:
1. 2-bromo-5-nitropyridine e sebetsana le methanol ho fumana 2-methoxy-5-nitropyridine.
2. 2-methoxy-5-nitropyridine e sebetsana le cuprous bromide e lokiselitsoeng ka sulfuric acid ho fumana 3-bromo-4-methoxypyridine.
Lintlha tsa Tšireletseho:
1. 3-bromo-4-methoxypyridine e halefisa 'me e lokela ho qoba ho kopana le letlalo, mahlo le pampiri ea ho hema.
2. ha a tšoara le ho sebelisoa, o lokela ho apara thepa e loketseng ea ho itšireletsa, e kang liatlana le likhalase tse sireletsang.
3. Ho boloka ho lokela ho thibela ho kopana le li-oxidants le li-acid tse matla, 'me u boloke setshelo se tiisitsoe.
4. Tlas'a maemo a utloahalang a ho sebelisoa le ho boloka, 3-bromo-4-methoxypyridine ke ntho e batlang e sireletsehile ea lik'hemik'hale, empa e ntse e hloka ho sebelisoa ka hloko.
