Isingeniso
I-2-Methoxy-3-methylpyrazine (eyaziwa nangokuthi i-methoxylate) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-Melafenone iyikristalu ekhanyayo ephuzi noma i-crystalline powder engenambala.
- Ukunyibilika: Ayincibiliki kalula emanzini, kodwa iyancibilika kuzincibilikisi zemvelo njenge-ethanol ne-chloroform.
Sebenzisa:
Indlela:
Kunezindlela eziningana zokulungiselela i-melafenone, futhi ezivamile zihlanganisa lezi ezimbili ezilandelayo:
- Ukwenziwa ngokusabela kwe-oxidation: I-2-methoxy-3-methylpyridine isabela nge-zinc chloride, bese i-asidi nge-asidi ukuthola i-methrafenone.
- I-Synthesis by substitution reaction: I-Methoxy-3-methylpyridine isabela ne-substitute (efana ne-methyl iodide) ngaphansi kwe-alkali catalysis ukuze kutholwe i-methrenone.
Ulwazi Lokuphepha:
- I-Melafenone iyikhemikhali futhi inezingozi ezithile.
- Gwema ukuhogela uthuli, ukuthinta isikhumba namehlo, futhi uvimbele ukudla.
- Gqoka amagilavu okuzivikela kanye nezibuko ukuze uqinisekise umoya omuhle.
- Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo yendawo.
