Selelekela
2,5-Dibromo-4-methylpyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela se qaqileng sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea komporo ena:
Boleng:
2,5-Dibromo-4-methylpyridine ke ntho e tiileng e nang le mefuta ea kristale e se nang mebala ho ea ho mosehla. E na le ho qhibiliha ho matla 'me e qhibiliha ka har'a lihlapolli tse ngata tsa tlhaho. Ke motsoako o sa tsitsang o senyehang habonolo letsatsing.
Sebelisa:
Motsoako ona o atisa ho sebelisoa e le lisebelisoa tse tala le reagent ho organic synthesis.
Mokhoa:
2,5-Dibromo-4-methylpyridine haholo-holo e lokiselitsoeng ke karabelo ea brominated p-toluene le pyridine. P-toluene e sebetsana le cuprous bromide ho etsa 2-bromotoluene, e ntan'o itšoara le pyridine tlas'a catalysis ea asiti ho hlahisa sehlahisoa sa ho qetela.
Lintlha tsa Tšireletseho:
2,5-Dibromo-4-methylpyridine e hloka ho tšoaroa ka hloko kaha ke motsoako o chefo. Tlhokomelo e lokela ho nkoa ho qoba ho kopana le letlalo, mahlo, le tsela ea ho hema nakong ea ts'ebetso. Lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana, liaparo tsa mahlo le limaske tse sireletsang li tlameha ho roaloa ha li sebelisoa ka laboratoring. Ha e bolokoa le ho tšoaroa, e lokela ho bolokoa hole le lisebelisoa tse tukang le li-oxidizing agents. Haeba ntho e metsoa kapa e hema ka phoso, ho lokela ho batloa thuso ea bongaka hang-hang. Ha ho lahla litšila, ho lokela ho lateloe melao ea sebaka seo 'me litšila li lahleloe ka nepo ho qoba tšilafalo ea tikoloho.
