Selelekela
3-Acetylpyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela ho tse ling tsa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 3-acetylpyridine:
Boleng:
Ponahalo: 3-acetylpyridine ha e na 'mala ho isa ho likristale tse mosehla tse khanyang kapa lintho tse tiileng.
Solubility: 3-acetylpyridine e qhibiliha ka har'a metsoako ea tlhaho e kang alcohols, ethers le ketones, 'me e qhibiliha hanyenyane metsing.
Lintho tsa Lik'hemik'hale: 3-Acetylpyridine ke motsoako o fokolang oa asiti o nang le asiti ka metsing.
Sebelisa:
Joalo ka k'hemik'hale ea organic synthesis: 3-acetylpyridine e sebelisoa hangata ho organic synthesis reactions e le solvent, acylation reagent, and catalyst.
E sebelisoa ho dae synthesis: 3-acetylpyridine e ka sebelisoa ha ho etsoa dae le li-pigments.
Mokhoa:
Ho na le mekhoa e mengata ea ho lokisa 3-acetylpyridine, 'me e tloaelehileng e fumanoa ka esterification reaction ea stearic anhydride le pyridine. Ka kakaretso, stearic anhydride le pyridine li itšoara ka solvent ka tekanyo ea molar ea 1: 1, 'me motsoako o feteletseng oa acid o eketsoa nakong ea karabelo,' me karabelo ea esterification e laoloang ke thermodynamically e etsoa. Sehlahisoa sa 3-acetylpyridine se ile sa fumanoa ka crystallization, filtration, le ho omisa.
Lintlha tsa Tšireletseho:
3-Acetylpyridine e lokela ho bolokoa le ho tšoaroa ka tsela e qobang ho kopana le li-oxidants ho qoba mollo kapa ho phatloha.
Latela mekhoa ea ts'ireletso ea laboratori 'me u apare lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana, likhalase le mese ha u sebelisa.
Qoba ho hema, ho e noa, kapa ho kopana le letlalo le mahlo, 'me u leke ho sebetsa sebakeng se nang le moea o motle.
Tlhokomelo e lokela ho nkoa ho qoba lerole le likaroloana ha u tšoara 3-acetylpyridine ho fokotsa kotsi ea ho hema.
