Nhanganyaya
2-Methoxy-3-methylpyrazine (inozivikanwawo semethoxylate) isanganiswa yeorganic. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
- Chitarisiko: Melafenone haina ruvara kune yero yekristaro kana crystalline poda.
- Solubility: Hainyungudika nyore mumvura, asi inonyungudika muorganic solvents senge ethanol uye chloroform.
Shandisa:
Nzira:
Kune nzira dzinoverengeka dzekugadzira melafenone, uye dzakajairika dzinosanganisira mbiri dzinotevera:
- Synthesis by oxidation reaction: 2-methoxy-3-methylpyridine inobatwa ne zinc chloride, uye zvino acidified ne acid kuti iwane methrafenone.
- Synthesis by substitution reaction: Methoxy-3-methylpyridine inobatwa neinotsiva (yakadai semethyl iodide) pasi pe alkali catalysis kuti iwane methrenone.
Zvekuchengetedza
- Melafenone ikemikari uye ine dzimwe njodzi.
- Dzivisa kufema guruva, kubata neganda nemeso, uye kudzivirira kupinza.
- Pfeka magirovhosi ekudzivirira uye magirazi kuti uve nechokwadi chekufema kwakanaka.
- Tsvina inofanira kuraswa maererano nemitemo yezvakatipoteredza.
