Intshayelelo
I-2-Methoxy-3-methylpyrazine (eyaziwa nangokuthi i-methoxylate) i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-Melafenone ayinambala ukuya kwikristale ekhanyayo emthubi okanye umgubo wekristale.
- Ukunyibilika: Ayinyibiliki lula emanzini, kodwa iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye neklorofomu.
Sebenzisa:
Indlela:
Kukho iindlela ezininzi zokulungiselela i-melafenone, kwaye eziqhelekileyo ziquka ezi zimbini zilandelayo:
- I-Synthesis nge-oxidation reaction: I-2-methoxy-3-methylpyridine iphendulwa nge-zinc chloride, kwaye emva koko i-acidified nge-asidi ukufumana i-methrafenone.
- I-Synthesis nge-substitution reaction: I-Methoxy-3-methylpyridine iphendulwa kunye ne-substituent (efana ne-methyl iodide) phantsi kwe-alkali catalysis ukufumana i-methrenone.
Ulwazi ngoKhuseleko:
- I-Melafenone yikhemikhali kwaye ineengozi ezithile.
- Kuphephe ukuphefumla uthuli, ukudibana nolusu namehlo, kwaye uthintele ukungeniswa.
-Nxiba iiglavu zokukhusela kunye neeglasi ukuqinisekisa ukungena komoya okulungileyo.
- Inkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo yendalo esingqongileyo.
